JTAG + PXA025 + flashing

Hello,
I have bricked Typhoon MyGuide 5500 XL pocket. Even it is based on ASUS 620, according to the site:http://www.handhelds.org/moin/moin.cgi/MyPal620JTAG I wasn't able to flash it.
Here is snapshot from jtag:

jedec_detect: mid 4, did ea00
Flash not found!
In internet I found another guy who faced the same problem (mid 4, did ea00), so it might be that it is something Typhoon specific, because I checked/fixed five times my cable, trying to make it as short as possible, then changed all the possible LPT modes (SPP, EPP, etc), then tested it with XP/SP2+Cygwin and Linux (Fedora Core release 2 (Tettnang), kernel 2.6.5) separately. The same problems. The flash is not recognized.
Can I pass some commands using jtag to the processor and in such way to manipulate with flash? What kind of commands? Where I could read about them?
Can I change BOOT_SEL[0] value to 0, which is now 1? Will it help?
Or do you know some more hints to make jtag to recognize my flash (M-SYS DiskOnChip G3)?
Thank you

[Q] touch screen not responding only when sd card is present

Hi all,
I have a problem with my defy, whitout fall or update the touch screen stop responding.
After some resets & sbf flashing I've noticed that the touch screen is ok only when there is no sdcard.
I've tried over sdcards with no more success.
The sdcard is readable, I can access with adb.
Clockworkmod access the sdcard too.
With sdcard dmesg :
qtouch_force_reset: Forcing HW reset
Unable to get gpio pin num for touch_pwr_enq
touch_write: Error while trying to write 2 bytes
qtouch_set_addr: Can't send obp addr 0x 0
qtouch_process_info_block: Cannot read info object block
qtouch_ts_probe:Cannot read info block -121, checking for bootloader mode.
Without sdcard :

qtouch_process_info_block: Object 38 @ 0x0101 (8) insts 1 rep_ids 0
(...)
Can it be a HW problem ?
What do you think I can do ?

Questions go in the Q&A section

AFAIK, it is HW related..
Best choice, get it to the SC..

Maybe I'll try to change the digitizer (20€ on ebay).
Warranty period is finish.

I want more log,
The goal is to enable logging debug in qtouch_obp_ts
I put in /system/etc/init.d/77debug
Echo 0xFF > /sys/module/qtouch_obp_ts/parameters/tsdebug
But no change at all...
What I am doing wrong ?

[GUIDE] USB Uart on Galaxy S devices [2012/09/25]

== General Info ==
Hello, and welcome to my usb uart guide - aka, how to totally f' your phone up, if you don't think first!
Really though, read everything before attempting anything!
USB Uart is not new news. There are many great people whom have come before me to make what I am documenting here possible. But I am putting this here because I keep getting PM'd about getting help with USB Uart, and figured it would be good to start a thread that documents what you need and how to get going.
So up front, I need to list some credits.
I gained a lot of knowledge from these people:
TheBeano - Fun with resistors (home/car dock mode + more)
UberPenguin - Galaxy S UART JIG & Debugging Connector
AdamOutler - UART Output / Bootloader Hacking / Kernel Debuging
E:V:A - The Samsung Anyway Jig
I'm sure there is more... let me know if you think you need to be in this list. I'll be happy to update it!
== WARNING ==
I am not responsible for anything you do to your device! If you follow my guide and it results from anything like your phone not working or ending the world, I cannot be held accountable for what you do!
This guide will show you how to use the usb uart on most galaxy s phones (with the FSA9480 USB port accessory detector and switch)
It helps to have Unbrickable Mod. There are some commands you can run from the SBL that will wipe your bootloaders!
You must be VERY CAREFUL!
== Requirements ==
First off, you will need some hardware to connect to your computer. It helps. Below is a list of things I use and they are common and cheap. The links to the items below are what I have. Its what works for me.
mini-usb cable - http://www.sparkfun.com/products/598
bus pirate or arduino (I only cover bus pirate here... for now.) - http://www.seeedstudio.com/depot/bus-pirate-v3-assembled-p-609.html?cPath=174
In my guide i use the bus pirate probe kit - http://www.seeedstudio.com/depot/bus-pirate-probe-kit-p-526.html?cPath=178_180
I used a tape printer to label the test clips.
breadboard (optional, if you rather just solder the resistor to the micro-usb break-out board. more later...) - http://www.sparkfun.com/products/112
USB MicroB Plug Breakout Board - http://www.sparkfun.com/products/10031
some jumper wire - http://www.sparkfun.com/products/124
150k, 523k, 619k resistor (ymmv. AdamOutler and others told me to try 523k or 619k, but I was able to get all the output I need with 150k)
guts - priceless
Also, I use minicom on Linux and Mac OS X (use homebrew to install minicom), but you should be able to use any serial console program you like (i.e. kermit, cu, etc...)
I highly suggest getting to know your bus pirate, but this guide assumes you have read manuals and updated firmware. Any of the other uart modes should also work this way, but I currently don't cover that here... yet.
== Getting Started ==
When we connect to the usb port on the bus pirate(bp), you can find the version info by typing i at the high impedance mode (HiZ>) prompt. Change to this mode when your modifying connections or cable argments.
Code:
HiZ>i
Bus Pirate v3b
Firmware v6.0 r1625 Bootloader v4.4
DEVID:0x0447 REVID:0x3043 (24FJ64GA002 B5)
http://dangerousprototypes.com
Disconnect the bp and lets connect everything from the micro usb port connecting to your phone backwards to the bp. I use a breadboard for things that I might work on later or things I'll re-arrange a lot. You may also decide to solder the resistor directly to the GND/ID pins, but you will need a little lead on the GND. Connect MOSI to D+ and MISO to D-.
Another warning!
You can also fry the ftdi on the bus pirate, if you mess with the connections while the bus pirate is in any mode besides HiZ (Hi Impedance) or unplugged. Usually, I'm in uart bridge mode, so you can't go back to HiZ. You just have to unplug the usb cable.

}
Solder some jumper wire to the micro usb breakout board. I use about an inch.
I usually start at a1 on the breadboard with vcc and a4 and a5 for ID and GND (respectively). In these images, I'm at the opposite end of the board to make it easier to have the phone next to and above my mouse so it is easy for me to work with the phone.
Put the resistor on b4 and b5 - which is where I connect GND on the bp.
Now that you have the bp connected to the circut, lets move forward and plug in the micro usb cable into the bp and then into your computer.
To change into UART mode on the buspirate, type 'm' at the HiZ> prompt:
Code:
HiZ>m
1. HiZ
2. 1-WIRE
3. UART
4. I2C
5. SPI

2. Normal (H=3.3V, L=GND)

UART>(3)
UART bridge
Reset to exit
Are you sure? y
After you get into UART Bridge mode, you will have to unplug the usb port from your computer to reset the bus pirate.
This is where experimenting with different resistors on the GND/ID pins make a difference. Using 619k resistance, I just plug the phone in and it boots up. During boot up, I can see the PBL output like the output you will see in the rest of this document. Using 150k resistance, the phone doesn't automatically turn on.
Also, you may have different usability of the console depending on if you set the output type to Open drain or Normal drain.
With Open drain, I am able to see the uart output, but I am not able to break into the SBL prompt like I am with Normal drain.
Interestingly, with 619k on my SGH-T959V, I don't see all of the kernel console output. I still haven't figured out exactly why yet. With 150k resistance, I don't see the PBL output, but I can still break into the SBL prompt (with normal drain) and get full kernel console output.
When you get to this point, the mode light should now be green. When you plug your phone into the micro usb adapter (again 619k in these examples), you should see everything from the pbl in to the kernel starting:

If we type help, we will get some commands you can run. Some of these commands are affected by what is set in the environment.
Code:
SBL> help
Following commands are supported:
* setenv
* saveenv
* printenv
* help
* reset
* boot
* kernel
* format
* open
* close
* erasepart
* eraseall
* loadkernel
* showpart
* addpart
* delpart
* savepart
* nkernel
* nramdisk
* nandread
* nandwrite
* usb
* mmctest
* keyread
* readadc
* usb_read
* usb_write
* fuelgauge
* pmic_read
* pmic_write
To get commands help, Type "help <command>"
SBL>
You can get some minimal help for each command:
Code:
SBL> help loadkernel
* Help : loadkernel
* Usage : loadkernel
load kernel image
- loadkernel 0x80A00000 from kernel partition
Another set of intersting commands here are the ones that manipulate the environment:
setenv
saveenv
printenv
Code:
SBL> help setenv
* Help : setenv
* Usage : setenv [name] [value] . .
Modify current environment info on ram
SBL> help saveenv
* Help : saveenv
* Usage : saveenv
Save cuurent environment info to flash
SBL> help printenv
* Help : printenv
* Usage : printenv
Print current environment info on ram
printenv is probably the safest of them to run, so lets try this first.
Code:
SBL> printenv

I'm not fully sure what all of these options are, but the ones I know about are SWITCH_SEL and PHONE_DEBUG_ON.
I usually turn SWITCH_SEL to 765431. If I turn 2 on, I don't get anything. It would be worthy to test each number in SWITCH_SEL to figure out what number changes what. That maybe specific to the device I have.
Setting at least 6543 in SWITCH_SEL will give you kernel log output:
Code:
setenv SWITCH_SEL 6543
saveenv
I also set PHONE_DEBUG_ON to 1:
Code:
setenv PHONE_DEBUG_ON 1
saveenv
When I set this, I get some extended battery statistics like:
Code:
[BAT] CHR(0) CAS(0) CHS(3) DCR(0) ACP(2) BAT(81,0,0) TE(31) HE(1) VO(3926) ED(1000) RC(0) CC(0) VF(591) LO(0)
You must remember that after running setenv, you must then run saveenv at least once at the end to save the environment. I believe this environment info is saved to either an offset on the sbl partition or on the param.lfs. It would be useful to find this out, because u-boot has a userspace utility (that you can use from within linux userspace) to modify the u-boot environment. It may be handy to use a tool like that to modify the CMDLINE option during rom flashing time.
Also, instead of powering your phone off then on again to put the new settings in place, just run reset from the sbl prompt to reboot the phone with the new settings.
Anyways, This is what I have so far. I will be adding more to this as time goes on.
Enjoy!

Very nice and clear guide!
Also check out my Anyway thread on more details about JIG resistances etc. Soon I hope there will be more added to that about building your own Samsung Test Jig...

Setenv switch sel 1234567

This gives you some kernel debugging.

Yup. I've got that in there.
It's interesting to note that not all bootloaders are created equal. My results are on SGH-T959V.

Any chance that it will work witch Galaxy Ace too?

I'm not sure. The GT-i9001 and the SGH-i717 (at&t galaxy note) also both have the FSA9480 chip, but use Qualcomm chips. I can only get some bootloader output from the SGH-i717:

E.V.A. said that it might be some debugging setting in the kernel that might have disabled the kernel log output.
It would be helpful to get some MSM developers here to help us out with that!

I looked in the kernel source and it have ./drivers/i2c/chips/fsa9280.c and the driver is included in the build kernel:good:. As far I understand we can using this method recovery the phone from hard brick? That will be really nice, my friend bricked his Ace, maybe he can use this method.

The switches are messages from levels 1-7. Turn on more to get more messages.

That makes sense, but what doesn't is if I set SWITCH_SEL to 1234567 or any combination with 2, I get no output. As long as I don't have 2 in there, it works fine. Must just be this device.

Memory Architecture
Of course each device will have a different Memory Map. Each carrier designs their varient based on what they want and need to function. The MM is sectioned off in the ROM. Any user or modifiable area is stored in RAM so remember we are working in an area that is not supposed to touched (ROM).
Bootloaders are tricky beasts, have never developed a flashing algorithm so I don't know. Usually BLs are not updated after release ( atleast in my field) only sw/fw is.
Either way, excellent ideas, but there is always a way in!

can't get SBL or PBL logs on uart in galaxy-y (GT-S5360)
Hello sir,
Thanks for your great tutorial .
I Tried to get uart on galaxy-y (GT-S5360) . I got a working uart but can't see any PBL or SBL logs during the boot. The only log I see during the booting is

AST_POWERON..
BOOTING COMPLETED
After booting, uart works fine and i can use a shell via serial using command
(on phone)
Code:
busybox sh</dev/ttyS0 >/dev/ttyS0
and on PC
Code:
microcom -s 115200 -p /dev/ttyS0
ttyS0 settings of the phone is
Code:
speed 115200 baud; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

I Tried to get uart on galaxy-y (GT-S5360) . I got a working uart but can't see any PBL or SBL logs during the boot. The only log I see during the booting is
Code:
AST_POWERON..

I get something similar on a Samsung Rugby Smart (SGH-I847). I think they have tweaked the UART stuff on the newer devices that post date the Galaxy S devices. They might share the UART chip, but it seems as if they changed the loader implementation which is causing the newer devices to not see the PBL and SBL information during boot.

Have you tried a 150k or 619k resistor instead of the 523k? I was able to get output with both a 150k and 619k, but the output was very similar to what you have posted. Likely a long shot, but worth a try.

Do you have any control over this? It might be the case that ttyS0 isn't setup during early-boot and you need to use a different tty to get it to output over the FSA chip.

yes I tried I didn't feel any difference b/w 619k & 523k when tried. And with 150k, I couldn't get uart active ()

What you mean by control? You mean, can i change this parameters? yes its possible by reflashing (update.zip methode)
Or
you mean do i have control on ttyS0 device? yes I could change that by
Code:
busybox stty -F /dev/ttyS0 ..........
command
Sorry for my language

This is the method I was referring to. If you tweak the parameters you might be able to get the kernel log over serial.

Can you please describe about the tweaks i have to do...
in my knowledge, kernel param
Code:
console=ttyS0,115200n8
is enough for that....
So please specify the tweaks...

If you can interact with ttyS0 post-boot I'd expect it to work. Is there maybe anther serial device such as ttyHS0 or similar that you can interact with? If so, that might be something to try.

You need to change that ttyS0 to ttySAC2 in the boot parameters. Use the abootimg tool on Ubuntu. Apt-get install abootimg.
