Linux 2.6-10.rc3 8xx: debugging (over-writing) content of b d_in fo structure in the kernel booting code

[Povolotsky, Alexander]

Sorry - no hardware instruments, support (and skills ;-) ) here ...
anything else to try software-wise (no JTAG debugging is available either) ?

If you can get your hands on an oscilloscope and look at the TxD from your
board, you can get an exact measurement of your baudrate and make sure
you are on the right track. (Baudrate = 1/shortest-high-or-low-time)
