Dear Madam/Sir,
our company, Microhard s.r.l, produces data acquisition terminals and in
our new design, which is under development, we use an ARM 9 plattform
based on the AT91SAM9263 microcontroller. Right now our system uses a
NAND Flash chip from Micron MT29F2G08AACWP and out Memory is mapped as
follows
0x0 AT91Booststrap
0x20000 *U-Boot (2009.06)*
0x60000 *U-Boot Env.*
0x A0000 Linux Kernel
0x400000 Rooot FS (jffs2)
We are trying to update the U-booot environment from U-boot with the
/"savenev"/ command. We encounter the following problem. When updating
the u-boot environment part of the u-boot code is overwritten with the
environment parameters. This happens only when our NAND flash has bad
blocks in the u-boot zone. (Block 1 and 2), We receive the information
about the bad blocks from Sam-ba. If we use a NAND with no bad blocks
everything works fine.
Could you kindly give any advise about this topic?
We looking foreword for your answer thank you for your time,
best regards
Jan Misfatto
