SIMpad forum / Upgrade Flash Memory

« on: August 05, 2011, 03:04:56 pm »

Thanks for the update
Do you have a simpad with the a flash mod?
I hope I find some time to test the loader (currently uni is eating all my time  )

If you like to further hack at the uboot front - adding some wake up code would be awesome!

Finally, I had some time hacking on this again. Suspend/Resume is functional right now.

Thanks,
Jochen

jochen, it seems that your u-boot image works also with my flash upgrade!  

Great. Except for the "too many flash sectors" error. I'll have a look if this limit can be raised using the config options.

But it would be to easy, so there ist directly the next problem: I think, that one or both of the RAM-Chips are damaged

I think this might be an easy one. The DRAM refresh parameters are set up for a (fixed!) 32MB RAM size. It seems to work for 16MB as well, but definitely not for 64MB.
I guess the read errors are from a non-refreshed DRAM line. So this refresh parameter setting needs improvement (possibly a dynamic setting based on the probed RAM size).

Thanks,
Jochen

My SIMpad is a CL4 with an additional flash chip added to the board.

Currently, I'm running U-Boot and OpenWRT on this device:

SIMpad forum / Upgrade Flash Memory

« on: April 02, 2010, 02:29:59 pm »

hi,

In theory you should only need to replace [1] those lines (simpad.h).

Code: [Select]

#define PHYS_FLASH_SIZE         0x02000000      /* 32 MB */
#define PHYS_FLASH_BANK_SIZE    0x01000000      /* 16 MB Banks */
#define PHYS_FLASH_SECT_SIZE    0x00020000      /* 128 KB sectors */
here [2] is a short description about how I build the loader a year ago

happy hacking
nice

1 http://git.linuxtogo.org/?p=mr_nice/u-boot...db2801abc8#l148

2 http://begu.org/?p=36

I updated the U-Boot loader. This should autodetect FLASH and RAM size. Current GIT is on:

http://git.bocc.de/cgi-bin/gitweb.cgi?p=u-...fs/heads/simpad

A precompiled binary is at http://www.bocc.de/u-boot.bin

Thanks,
Jochen

SIMpad forum / Bootldr Source

« on: November 27, 2005, 09:55:25 am »

Does anyone know where the current source code for the bootldr for Simpad can be found?
http://opensimpad.org/bootldr-simpad/ only seem to have the binaries while the CVS at hh.org doesn't have SIMPAD support.

SIMpad forum / Opensimpad-0.9.0rc1 On T-sinuspad!

Hi Berend,

in the meantime, I gave the gpe-image a try, too with the same results.
I'm not really sure if there is a major problem with the bootldr itself leading to these problems or the images which maybe rely on an existing home partition or whatever.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=104937\"][{POST_SNAPBACK}][/a][/div]

One problem could be the different memory size. While bootloader detects the smaller device with 32MB main memory, the kernel assumes 64MB and behaves strange when trying to use nonexisting memory. I sort of fixed this by adding mem=32M to the kernel parameters on my "pimped" CL4 (added second flash chip to the main board).
