Would someone help me solve this problem?
The TS-7250 board worked correctly before uploading the new TS-Linux
into it.
Here are the steps that were taken.
1) Downloaded the "vmlinux-ts7250-ts9.bin" from ftp server:
ftp://ftp.embeddedarm.com/pc104-peripherals/ts-7kv/ts-72xx-linux24/
2) "fis init -f" to format the flash on the TS7250 from the redboot.
3) "load -v -r -b 0x00218000 vmlinux-ts7250-ts9.bin"
This command loads the kernel from the defaut tftp server
4) fis delete vmlinux
5) fis create vmlinux
Here is output of the "fist list" command:
----------------------------------------------------------------
RedBoot> fis list
Name FLASH addr Mem addr Length Entry point
(reserved) 0x60000000 0x60000000 0x07D20000 0x00000000
RedBoot 0x67D20000 0x67D20000 0x00060000 0x00000000
vmlinux 0x67D80000 0x00218000 0x000C0000 0x00218000
FIS directory 0x67FE0000 0x67FE0000 0x0001F000 0x00000000
RedBoot config 0x67FFF000 0x67FFF000 0x00001000 0x00000000
-----------------------------------------------------------------
6) Modified the fconfig script as follow:
fis load vmlinux
exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"
7) Restart TS-7250 Board
Here is the output:

-------------------------------------------------------------------
What is causing this error?
Why can't the bootloader recognize the "mtdblock1"?
What do I need to do to get the new kernel installed on the TS-7250
board?
If you need more info, please let me know.
Thanks.
