Topic: Flash Kernel/Rootfs on CC w/o screen
I have pulled off the touchscreen on an old Chumby Classic and I'm wondering if there's a way I can boot from the "alternate" root filesystem and flash a custom kernel/rootfs.
If that's not a possibility, is there a way to "dd" them to one of the mtd partitions safely from the running linux distro and simply reboot into them? What about getting back? Any gotchas?
Is there any sort of alternate bootloader so I can use the entire flash space for 1 larger rootfs instead of 2 smaller (normal and "update") filesystems?
I have serial console access, but there doesn't appear to be any break point to change the boot.
The only interesting bit I see at the bootloader portion is "MSP is cleared; flagging normal mode." I'm guessing there's a bit I can set to signal an alternate boot?
