Hi,
would like to check which of the WM5 device has its JTAG points exposed on the PCB?
Thanks

:shock: Is it possible to use the serial cable for he iPAQ for the O2 XDA?
Thank you for any help.

No, not without modifying the cable. Everything is connected to different connector pins on the XDA, relative to the iPaq. The connectors page on this site has all the details.

no, you have to modify it
As always the XDA-developers solution works.
I have changed an IPAQ cable according to information on the prementioned page and it works flawless.
Just make sure you:
- have a fine tipped soldering iron
- a steady hand
- patience

Use an ohmmeter (or just a battery and a light) and two VERY finetipped 'probes' (I used two needles :lol: ) and check every pin on the connector against the two pins on each side to see if they have a connection or not. It's a simple but effective way to prevent damage to your XDA just because you overlooked a connection.

XDA developer You are a clever people, all many thanks, shall probe change the cable from iPAQ.
:lol: With many thanks for help!!!!!!
Fredy.
climber i want to modify an ipaq usb cable to use it for synchronization with my XDA II. Can you provide me with some detalis? I don't understand what conectors i need to change from that link. I prefere something like "pin1 to pin3" or something like that.
Subj. Does anybody research the JTAG way?
I have an information what pins on PXA272 are JTAG interface. But I don't know where it's pins traced out on mainboard. The separation of PXA272 from mainboard is impossible in my case(for a while).
Does anybody know JTAG pins on mainboard for ATOM?
What tools for PC can support JTAG? Can I make a LPT-device for the connection PDA to PC by JTAG?
Did you find jtag pimout yet ? I have the same problem as yours, dead atom !
Basicly, I've seen couple connector in PDA which I believe are JTAG pinout, I've seen it in ETEN and in Atom it seem placed near the simcard holder. You'll see eight gold circle contact on the PCB, I believe six of them are JTAG pinout.
But still can't find the info about those specific pinout.
Still find the soft, mostly run under linux needed in win
I guess JTAG is my only option for waking up my atom, so if you have any info regarding this matter, would you please share with me ??
Thank you
Hi folks,
Does anyone know if the Uni has an accessible UART (hardware serial port) anywhere on the motherboard? I want to physically connect to a device that needs serial access. I'm happy with level-shifting from 3.3V to RS232, which I assume I'll need to do - just need ot know where there is a tx and rx pin that I can get to.
Cheers if you can help,
Johnny_G
Is there any progress after 7 years ? I need uart too, but maybe it`s impossible in universal?
Hi,
i found some pins on my mobile phone that mostlikely will be some jtag pins
(since i found serial already).
Now hard part is to find what pin is jtag and what not.
I am not seem to be able to find information how i can eliminate pins.
Does anyone of you have any tips or howto´s?
ps desoldering mt fpga cpu is not an option
thanks!
No-one?
Common guys (&girls) !
I remember it here as the forum to get such help or information!
I am sure plenty of you guys should have experiences with jtag´ing
mobile devices!
Maybe i did not post enough information;
it has an arm s3c6410 (pins are hidden under the fpga),
so i know it has jtag and serial debug (witch i found).
My device has +-22 pins around the simholder that are reachable and show some reading while testing voltages , a few of them should be jtag since there are no other testpins on the pcb..
So if any of you could point me to a howto or
explains how to find some important pin(s) i think i can manage it.
Hi
I became the owner of unknown Elf. I know only this one was purchased on eBay then bricked by flashing incompatible firmware.
Today the Elf switching on and i can see the welcome screen only. When i connect the pda to my computer Activesync try to recognize, but can't obtain IP address (tried all the found Activesync IP address solutions, but no way). When i try to enter to bootloader (Camera + Reset) or make a hard reset (Red+Green+Reset) , i see the same welcome screen.
When the powersupply connected lights the blue led and Reg and Green buttons. When connected to the switched off, charging accumulator animation appears.
I tried to find JTAG contacts how read on pda2u forum, but no way too. No contacts in the place because the PCB is different (See atachments), but OMAP 850 onboard.
Anybody knows where can be JTAG pins on this board?
What i can do more to debrick?
You sure this was from a genuine HTC? Did you remove the stickers on the board?
Looks odd compared to the HTC Touchs I have....
Thank you for your reply, captainstu72.
I think, is not original, regarding Dopod site shortcuts in the firmware. But i obtained this PDA w/o any stickers, the glue only.
I reanimated this PDA by finding Hard reset combination (Green+Ok+Reset) but can't enter to the bootloader (not shortcuts [Camera+reset; ], nor EnterBootloader.exe does not works for this device)
As thats the case (the HTC shortcuts not working) I would suggest this is a clone.
You can trace the JTAG points yourself, it should just be a case of finding what pin out is what on the omap chip, and finding where it ends up. There should be a fair few bits on the internets about this, however, can take a bit of searching from my history with JTAG.
If you do it successfully, please bear in mind you will need to use the firmware for that phone, and the ELF firmware would not necessarily work.
I do find it odd you were given a phone with no stickers and not working. I'd say its stolen, as you have no way to check the IMEI now....
