2009-12-15 04:51:29     uboot won't start ...

hi,

 

i am using a custom selfmade board with the bf536, rev0.3, 400MHz.

 

the board is running for many hours at 393.213MHz (16.384MHz) and the bfin gets a bit warm(i guess 30-35°C). when pressing the reset-button the bfin should start the uboot but nothing happens ...  after i cooled down the bfin with some ice-spray, press the reset again the uboot starts as expected!

 

 

 

has anybody also noticed this problem?

 

br,

andy

Try seeing if U-Boot is starting, or if the problem is in the BootROM. Try this, and see if you get any output on a warm re-boot.
