Does anyone know how to manually Read/Write ROM from the Yeti Boot ROM ?

Does anyone know interesting commands that can be used on the ROM Boot Loader ?

I did manage to figure out a way to start the ROM Boot Loader but i'm not sure how to play with it :)

Trying the BOOT commands at random doesn't sound like a good idea :)

BR sounds like it might be safe to play with. I expect that it would set the baud rate divisor for the UART.

Try "BR" or "BR ?" or "?BR" or "BR 0" (zero).

The last one should produce an error and hopefully a list of permissible baud rates.

DS asks for a file name, so it must be related to data transfer (XMODEM / YMODEM / ZMODEM ???)

RD reads memory addresses.

GO probably begins executing at the specified address.

TE might execute a particular test number ???

you must have special code for writing ROM, code must be loaded into RAM and executed
