[ANN][MINI2440] modern u-boot (openmoko) git repository

[buserror]

I've uploaded my git tree based on the openmoko's u-boot branch, with support for the mini2440.

http://repo.or.cz/w/u-boot-openmoko/mini2440.git

U-boot works from nand, and allows loading via ethernet, mcc etc with pretty much all the modern extensions you would expect.

I'm working on doing the same for the kernel, so watch this space.

Hi,

I found that u-boot (openmoko) on real mini2440 does not skip bad blocks.
I load u-boot. Do 'nand scrub'. After do 'nand createbbt'
and after try erase and write area where found bad block and get write error.

Code: Select all

MINI2440 # nand scrub

NAND scrub: device 0 whole chip
Warning: scrub option will erase all factory set bad blocks!
         There is no reliable way to recover them.
         Use this command only for testing purposes if you
         are sure of what you are doing!

Really scrub this NAND flash? <y/N>

Thank you buserror,
This was my fault.
If somone has same problem use 'nand write.e ...' cmd.
I found answer in MiniBringup.
