Upgrade Flash Memory

[mr_nice]

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!

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:

nice you did a kernel update
I realy hope to be able to find some time to test it :/

Did you try to sleep/wake up the simpad with uboot?

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

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
