With the comm port set to 38400-8-N-1, we get the following output:

If you hold down any key as you power on the device, the sequence stops after "This version of fips..." and the MG35 is waiting for a pasword to be entered. The correct password is:
Note the capitalization and the period at the end.
Commands
On the serial console we have commands to download kernel and cramfs filesystem, and even flash them.
pbarette: The bootloader saves the config settings, but I can't get it to save a new default serial baudrate. I usually connect at 38400 then issue "config serial 115200" and disconnect, change the baud on my comm port and reconnect. Since the serial interface is a 3-wire deal, the MG35 doesn't notice the dis/re-connect at all.
Todo: add here the commands.
gadgetmind:
What "boot image" expects is a full rom image at 0x1400000
So -
boot> memcpy 0x1400000 0 0x400000 (4MBytes of rom to 0x1400000)
boot> boot image
Results in a successful inflate of the kernel and the box booting. However, it's currently hard to tell if it's using the new kernel and/or cramFS.
I guess I'd also need -
mem wl 0x1440000 0x014e2809
to tell it to use the new cramFS
pbarette:
The command "flash romfs" erases the flash region from "0x40000" to "0x3FFFFF" then it writes the contents of "0x1400000" into that flash region. So I didn't try to use memcpy to do that.
Also note that there's an unlisted "config save" command, but that doesn't seem to change the default baudrate either.
