RE: [microblaze-uclinux] No boot log in hyperterm

I would try dropping the baud to 19,200 and make sure you have your pin
mappings going to the right pin in the UCF file. Sometimes RXD and TXD
get "mis-labeled" @ xilinx

Folks,

  Sorry again to be such a pain. I changed the UART clk frequency in the
MHS 
file and I still dont see anything in minicom or hyperterminal. I
haven't 
brought out the O-scope yet, but I will very soon for a meager sanity
check 
that at least something is coming out of the serial port. If someone has
the 
time, please browse my MHS file and see if anything is starkly
incorrect. 
Keep in mind this should be exactly like the MHS from Wu's getting
started 
tutorial.

Thanks,
Andy
