128 Mb RAM on Universal

[Fashist]

Hi, All!
I have upgrade Universal to 128 RAM (phisicaly), but WM5 couldn't see them.
I tried all available ROMs.
Could you help me.

Oh nice. So you have finally made an upgrade. But i dont think 128MB is the max? Did you order 64MB from hynix or Infineon?
Did you solder them on? And they are not recognized? Did you remember to flash them after you soldered them. Usually you have to flash the mods after you hook them up into the motherboard. Read the manual that came with the RAM.
The signals are just not reaching the RAM to get it initiated and working. Universal might not detect them in the ROM like it does not detect my 8GB SD cards full memory and keeps saying 2GB.... The RAM might be working but to make sure try running a heavy application and see the time difference, that is if it is faster or slower. Or try playing HD videos, copying files, running multi-processes. Try using task manager if that helps, should show how much RAM the device actually has.

Ошибаешься, при загрузке РОМа идет тест кол-ва памяти, соответственно если ОС не видит 128 - значит память припаяна криво.

Why are you guys posting in Russian? I thought this is an english only forum.

[arc]

Я думаю что тут проблема не кривости припайки памяти а в сигналах Cs и других т.е. фактически запаять память не проблема - а вот проконтролировать прохождение всех остальных сигналов уже будет проблематично ,насколько ты знаеш уже пробывали припаять спецы и пока что неполучается - или я ошибаюсь ?

I believe it is a limitation of the operating system (WM5) and it cannot address memory beyond 64 MB, otherwise why no manufacturer has to date made RAM in excess of 64 MB available to us.

Now you can find quite a few devices which have 128 MB or even more of ROM but RAM is still at 64 MB by all. We do not urgently need a very large ROM becasuse this is something you can always substitute through an SD card but RAM is the real thing and unfortunately WM5 devices to date are marred by shortage of RAM. Try loading one of the very large web pages and before the page loads the device runs out of RAM.

Anyways a good effort and hope you are somehow successful.

You are absolutely wrong. There are at least two WM5 devices with 128Mb - Himalaya and BlueAngel. CE has a memory limitation - it can address 256Mb of RAM for user programs, and 512Mb more are available to kernel (hardware control registers, etc).

I've created a test program that tests the RAM amount available to OS:
http://slil.ru/23593566 (or attached to this post).
Copy it to device, run it, select "Test1" and write here the output.
Then select "Test2".
Test1 - is a test extracted from NK, on 64Mb it would output "ReadData != WriteData", then "Mem = 64M".
Test2 - is my own test. On 64Mb it would output "Exception while reading >64M", then "Mem = 64M".
You should test it on 128M and write here the messages. If they are the same - you've incorrectly soldered chips. If they are different - you are lucky, and there is a bug in NK.

hi! i tried your TESTmen, and the out put data was same as yours '64MB'
i got incorrect chip :(

Hello Buddy,

If RAM upgrades succeded then I would like to do it.
It will be great if someone write a detail how to for the RAM upgrade, i.e. dissemble, chip soldering etc.

Thanks.

Hmm.. If i am able to upgrade my Universal's RAM I will let you all know. Right now i think it is one of the fastest upgrades I can make.

[agisofttm]

hmmm - a realy nice topic - well actually I've tested this last day and I'm absolutely sure that I've soldered my memory perfectly - I've got it from other universal - but here is the same problem - the device just don't see 128MB of memory - after many hours of think and test we are absolutely sure that in Universal WM5 just is not managed to address this memory - may be - some of GURU's here can acomplish that addressing task with some of existing ROM's :) :) :) :)

Well i am going above 128MB and i am also adding flash memory. Also i have the exact symmetrical pins on the RAM and the flash memory. So I will be getting them soon and soldering them on ^^.

Is it not a limitation of the PXA270 processor fitted to the Universal, that it can only address 64mb + 64mb (Rom + Ram)?

Thanks for addressing that Jason. I am awaiting a reply from Hynix regarding your question. I will post it here as soon as i recieve the reply. I had the same question too and I had emailed Hynix. I am waiting for their reply. Hopefully in 1 to 2 business days I will recieve their reply and get some production going.

[JDark]

Hi All,

I upgraded this Universal. I'm sure, chips are installed properly and there is low probability, if there is one faulty.
I upgraded myself more, than a hundred hx4700 and Magician without any problem, so I suppose, I experienced enough.
So the first I did, removed old chips (256), checked - where is E2 pin, it's extra chip select, this pin is not used on 256 chip and present on 512 chip. I found it on a pad between memory chips, unconnected. The nearest pad looks like desighed to mount smd 0204 type between them, this pad have protective diode on the other end, however I did not remove CPU, so, I have no exact pin number, connected to this pad.
I soldered a 30 Ohm resistor between them - same, as in Magician required.
There were no change, however I suppose, if there is a connection on this pin, which is not used on 256 chips, there is a hardware possibility for upgrade. Unfortunately, I'm not a programmer, so, I cannot write any utility to check, if this memory is available for OS anyway (like T2T disk for example).
If you look at the photo, posted by Asukal - you'll see same pins, connected by wire jumper - it's less "proper" but... works ok.

So, is there any smart person, who knows how stuff works and can write utility to check, if extra memory is addressable?

[mamaich]

PXA270 does not have such timy limitation. hx4700 has the same CPU and can address 128Mb RAM.
Universal has 0 (zero) bytes of NOR ROM, so you should not count the first 64Mb (ROM).

[mamaich]

So, is there any smart person, who knows how stuff works and can write utility to check, if extra memory is addressable?

Can you read my previous post? Utility is attached. "test2" button would directly access A4000000h physical address and would write the message if it would succeed. As you may know, RAM on uni is located at A0000000 physical address, and A0000000h+64Mb = A4000000. So if my program can access it -> it is correctly soldered.
I've looked in RAM initialization code in NK, it is nearly identical to hx4700, so this is not a software issue.

[Pyrojester]

Should we just take it as given that everything Nuclear says is BS? some of his "advice" seems to encourage heavy spending with little or no reward. (8gb SDHC, 6400MaH battery with *cover* and so on) Its all not true, and I mean that in the sense that he is just lying outright.

[JDark]

Извиняй Мамаич, не заметил :(

Well... if some of my friends will help, I'll get a board from hx4700 and other one from Universal to check - what CPU pin is (should be) connected to CS2 memory pin. Also (maybe) I'll get 100% tested on another device memory chps and replace existing, to be sure, there is no faulty chip.

Those CPUs... I relly hate to reball them ;).

[JDark]

2 mamaich - yes, exactly. Red line on photo (chips removed) shows internal wire connection. Question mark - pin, that is probably, connected to CPUs extra address line.

I've attached the foto.
points from left to rigth: p.1 - should be short cuted, p.2 - not connected, p.3 - 51K, it would give 2.5v to RAM chips.
As we think this should be enough.
p.2 may be used when you'll solder 4 256Mbit chips.

[Midget_1990]

just a thought here - on the BA (my old device) you could change the amount of memory used by WM5 by editing specific HEX values in the NK.nbf. (that's how we used some as RAMdisk)

Would this be a possible solution? (Ask maimach where to patch, afaik he found it on BA's :) )

As long as the Hardware is functioning and the system detects it and uses it. It doesn't matter what the Memory Panel is showing. Just fix the memory panel in the next ROM release.

[mamaich]

This would be possible only in one case - if my test program attached in previous posts would not output "read error" on test2. I.e. if the RAM would be physically present on the device.
Otherwize - the RAM is incorrectly soldered -> not acccessible.

i believe this was not coz of OS, but a hard ware or assemble,,
thats why no error on mine.just read previouse ram.

lol... you bad at soldering Asukal. Tell me where you order the RAM from? Infineon or Hynix? I need RAM too. Hynix not giving me. I am being ignore by Hynix.

Can you tell me where to order part from?

Can you test the attached program on your device?
You should press 2 buttons (first 2 are useless):
"Test+96" and "Test+128"
If they would output anything different from "Exception while reading >64M" - your RAM is accessible, but it is just located after a 32Mb or 64Mb hole. So you are lucky - and all we need is just a tiny patch.

[mamaich]

these tests are also failed

Anyway, thanks

[georgel]

I am not a pocketpc guru, but to my knowledge from x86 pcs prior to OS booting
all DRAM should be detected and set in SDRAM controller (e.g. chipset in PCs). Thus different types of SDRAM chips are set for refresh and their address space is mapped contiguos (e.g. without holes). Also appropriate timings are set, etc. All this is done by BIOS and then control is transferred to the boot sector of the booting drive. Since there is no BIOS in PDAs this should be accomplished (i guess so) in bootloader. So look for our problems there!

[mamaich]

UP!

I've found a bug in a test program
This was not really a bug - kernel disables the second SDRAM partition after it fails to detect it, so I've changed my program so that it forces partition to be enabled.

Attached an updated version, can someone test it?
Usage: run it on the device, press all the 4 "test" buttons and write here the exact error messages.
If it would write: "Mem = 128M" - we are lucky, all we need is a simple kernel patch.

Edited:
there is still a bug, later I'll upload a fixed program

i am teseing,

Any way
Test1= Read Data!=WriteData---then "Men64MB"
Test2= Men128MB
test+96= 96M
Test+128= Exceptopn while readinf>64M then "Men 64M"

still possibility of extra mem on my device?

I'm asuming you are that mamaich from pgg c++ compiler fame... if so, well then you are good! hope this works!

and, a little bit off topic, wonder if that c++ compiler works on htc universal? couldn't test it on my axim x51v and had forgotten about it.

For actual device with Mem = 128, the result is still 64?
