Unable to Boot from NAND on Mini2440

Unable to Boot from NAND on Mini2440

[Vikram Narayanan]

Hello,

I followed the instructions here
<http://barebox.org/documentation/barebox-2011.04.0/mini2440.html>

After writing to NAND, I switched the boot mode to NAND and did a reset. 
Nothing comes up on the prompt. I tried to verify the 'write', by a 
'nand_boot_test'. That works. Please find the log below. I'm on the 
latest master.

Any idea on what goes wrong?

Hmm, never had a Mini2440 with a 1 GiB NAND. Can you see, what kind of SDRAM 
devices are on your Mini2440 board? Maybe they also changed the SDRAMs...

Sorry, I can't help you here. I think Juergen can tell you more once
he is back in the office.

Sorry, I was totally away from mail access.
Here is the name on the chip.
K4S561632N -> 256 Mbit x 2

Vikram

This memory is different from the HY57V561620 and MT48LC16M16 types I know and 
Barebox is adapted to.

Maybe your system doesn't come up due to a wrong SDRAM configuration.

You should compare the SDRAM datasheets and check if the SDRAM controller 
settings in Mini2440 'config.h' match the requirements of your SDRAM type.

Regards,
Juergen
