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

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

I noticed this same thing in a BSB-produced MHS file the other day (for
an old Insight board, I'm assuming it's the XBD file at fault).  The
system is clocking at 66.666667 MHz (100/1.5) but the uartlite
clock_freq was set to 66000000.

You should correct this in your MHS file - as a recent discussion here
revealed, some PC serial ports are more sensitive than others, when it
comes to RS232 timing.

Regards,

John
