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 -- */Jan Misfatto/* */Microhard/**/ S.r.l./* *Tel: +39.0331.514420* *Fax: +39.0331.514707* *e-mail:* *<jan.misfa...@microhard.biz>* --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- /Questo messaggio ed i suoi allegati viene spedito solo alle persone indicate come destinatarie.
