Storage question

I really don't understand this. Maybe somebody can explain this to me:
according to the spec the htc herald has 128MB of ROM and 64 MB OF RAM.
But where is this storage ?
In the memory setting it says approx 32 MB Storage (Total) and 44MB program total. (Btw, I use TouchIT 2.0 ROM. The size of the ROM (OS.nb) is about 62MB) .
How comes that others mention values of about 50 MB. Why is there such a difference ? And where is my memory?
Thanks for clarification!

My Legend has less RAM than stated. System info: RAM: 291 MB ROM: 185 MB

Hi all,
I notices something really weird today. I have installed a couple of System Info applications from Market (Android System Info, Quick System Info) on my Legend and these apps are displaying the same thing:
RAM: 291 MB
ROM: 185 MB
Official HTC Specs:
RAM: 384 MB
ROM: 512 MB
WTF??
Did someone else noticed this on Legend too?
I also tried another sys info app called Device Information. It states "Total Usable RAM: 291 MB". WTF?
Please mates, try it on your Legend and let me know if just mine is f*cked up.

Just checked on mine with android system info: I have exactly the same "issue".
Maybe the rest of the ram/rom is allocated to the OS and therefore not "visible".

I assume that these Sys Info applications does not display correct information. I tried some more similar applications and tested on HTC Tattoo also - it seems there are some hardware reserved system resources which are not discoverable by the apps.

Actually the value in /proc/meminfo also shows 291MB. Is there something between Linux kernel and the hardware itself that could take the remaining 96 megs?

I have the same problem.

Do you all have rooted phones or not? I think that if the phone is not rooted, some part of memory is locked.

My phone is rooted and it has 291MB of RAM.

This is because of the limitations of the 2.6.29 linux kernel, used in android 2.1 not the device itself. This should be resolved with the next release.

The memory will be fixed with the 2.2 froyo update?

should do
Android 2.2 users 2.6.32 kernel which supports HIGHMEM support for RAM >256MB

old post I know but I've got 2.2 and apps still report 291mb of ram. I presume the rest is hidden by the system and not anything to do with the kernel not using the memory ?

I'm testing " The NewSense 1.0 alpha 6 " by @ogo2 and it is the same :
ROM : 185.1 MB total
RAM : 291.4 MB total

ahaha:-DDD
did your really think that a problem?)
"i have the same problem"
very funny, thx guys

Do not worry, it should be! memory depends on the ROM

[Q] HD2 Android RAM utilization

I was reading this thread and a question popped on my mind: http://forum.xda-developers.com/showthread.php?t=765578
As the thread suggests that ramsize is set to 0x1e400000 for fullram builds. In decimal, that would be 507510784 bytes or 484MB (1k=1024). As we know, HD2 has 576MB RAM.
Q1: Why didn't we use more than 484MB while we have 576MB?
Q2: In WM6.5, 128MB is reserved for GPU. Does android not need this reservation? When 484MB is used, there is only 92MB left for reserved use.

Well, HD2 Android is based on WinMo IMHO.

I think Android runs independently and has different memory allocation. On WM6.5, the program memory allocated is only 448MB if I'm not wrong. It's quite different from the Android that we use in these HD2.

afaik, android is NOT based on winmo. it actually needs winmo to initialize some hardware. android is not emulated or run under winmo!
winmo and android surely will have different and independent MMUs.
or am i wrong?

Android uses the full 576 assuming a radio that unlocks it. The problem is that as it doesn't run from NAND, it currently loads it's file from the SDCard into memory. The "loss" of memory isn't lost so much as used by the OS itself as running space.

I didn't know radio ROM has something to do with the RAM. This is new to me.
Wrathlon, you're saying that we are using 484MB because the rest of 92MB has to load Android from the SD?

[Q] Windows CE 6.0 Upgrade

Hello guys,
I recently bought a device named "Zune HD", a windows CE based pda/media player made by Microsoft. Looks like a WP7.
The windows CE version is 6.0, and I want to upgrade it to WinCE 6.0 R3 .
Its now that I need help:
-What I have to download first?
-Will it destroy my Zune if I upgrade to R3?
-Am I able to do this or it won't work anyway?
-A little step-by-step tutorial should be nice
Tech specs of the Zune HD (If it helps):
Memory: 128MB Hynix SDRAM
Disk space: 16 GB (12 avaible)
GPU: NVIDIA Tegra APX 2600 (HD)
CPU: NVIDIA Tegra APX 2600 with on ARM11 and one ARM7 general processing cores -> 800MHZ I think
Screen: 480X272 OR 3.3 inches OLED screen
Nice for a media player uh?
IF YOU NEED PICTURES OR ANYTHING ELSE LET ME KNOW.
I think that's all! Thanks all for your time

are you trollin'?

no and you?

very nice, thank you buddy

lol...
But this is not a blabla topic, anybody has a real answer???

First, you'd need the original BSP for this.
Second, you'd need to get CE6R3 full package (although the open one for download might work too, if you'd have the rest of the files).
Third, access to bootloader to flash it.
Simply said, not gonna happen, unless MS does it themselves (which I doubt).

[Q] What is the RAM on hd2???

Yes, this is normal. It has 576 Mb of RAM but it's something to do with Android, I really don't know why exactly this happens. In the past couple of days there have been two threads about this subject, and there were many more before that, so please search before posting and read those for much more in-depth explanations of what happens because frankly I don't know why.

Physically it has 576MB but in system is available only around 400-410MB (depends on kernel), so everything is as it should be. It has been answered many times

128 for graphics chipset taken at boot, so 410/420 + 128 = 550 so only 26 meg missing, , ,

Here is the detail answer from Rick_1995..
Leo has 576mb ram, the kernel and SPL, IPL map some normal and IO memory for special devices like DSP, AMSS etc.. and some is taken by the kernel drivers such as msmfb (framebuffer), kgsl (graphics), wireless etc.. Depending on which kernel you're using and how the driver is mapping stuff, you can have more or less ram than 403MB, if you're speaking of the Dorimanx's thread, I was telling him about his wrong conversion method and NOT about the amount of ram available to dalvik.
eg. Tytung's older kernels have 411MB available to dalkvik, earlier kernels which didn't map the extended bank properly had ~200MB available to dalvik. If you're willing to take out some drivers or optimise some of them you can have more than 411MB too. Windows phone reserves even more memory to kernel space stuff and has only about 375MB available to userspace in tango.
As for 448MB, the EU version had the rest of it's 128MB from the total 576MB (reserved/blocked ?) by the radio which was later unlocked by flashing a .50 TMOUS radio to the EU version.
It is just like seeing 3gb ram on a 32 bit computer with 4gb physical ram (though here instead of actual ram, the address space is reserved for various peripherals)
