u-boot on the DB64360
Hi,
I've built u-boot for DB64360 config for the IBM eval board. I loaded it onto the flash via BDI, but see no output on the serial console. I haven't yet stepped into the code; I just wanted to know about the status of u-boot on this configuration.
Thanks,
Amit.

I ported this board over to our in house designed board based on this system controller and it works just fine. What problems are you having...

I put the u-boot binary in the Flash area and reset the board. I didn't see any console (serial) output, rather I saw some junk characters. The baud rates were set correctly.
I didn't have to modify anything in the config, since everything was set correctly (baud, processor type, etc).
BTW, this is a board with two 750FX processors.

Are you sure the baudrate is set corectly. What you described sounds like a classic clock divider/baudrate not set correctly...

Right, so I double-triple checked. Both, minicom and the include/config/db64360.h are at 115200.

Please read again what Frank wrote: "...clock divider/baudrate not set correctly...", i. e. check your clocks, clock dividers, BRGs etc.

Yes, the divisor, clock rate, etc, all too are correct.
By the way, my BDI isn't working right now. Is there any way of knowing if something's happening over PCI? Can I get to know the value of the Instruction Pointer?

Use the "info" command at the BDI telnet prompt.

hmm, don't have one here, will have to go to some hardware lab.

I'll report back when I get the BDI up and with my hacks on what made serial output work :-)
