Hi, I'm using MVL 3.0 (kernel 2.4.18) on a PPC 405GPr custom board. Flash memory on the board is located in 2 AMD641DH flash chips, which are concatenated on the mtd layer to one large flash memory area. The flash is divided into 5 partitions (bootloader u-boot, 2 bootloader environment partitions, kernel, rootfs).
When using the fw_setenv tool that comes with u-boot on the linux console, I can write the bootloader environment sectors without problems. When calling fw_setenv from an expect script, which also does some write accesses on the rootfs partition, I get the following error message when trying to write the bootloader environmen afterwards: [root at SERVICE update]# Set the bootloader to flash mode ... /mnt/install/fw_setenv "rootfs flash" "kernel flash" "serverip 192.10.11.95" "ipaddr 10.0.3.14" "netmask 255.255.255.0" "gatewayip 10.0.3.25" Unlocking flash ... Done Erasing old environment ... Done CRC write error on /dev/mtd1: Input/output error Error: can't write fw_env to flash Writing environment to /dev/mtd1 ... [root at SERVICE update]# ... Timeout. (child process exited abnormally) The respective environment sector has been erased, but writing the new environment didn't work. If I insert a 'sync' command between writing on the rootfs partition and the fw_setenv call, writing of the environment sector works, but this is not really a solution??? When trying the same procedure on another custom board with PPC405GP but only one flash device and same partition scheme (no concatenation necessary), everything works without a problem. Any ideas, comments?
