If 'go 0' and 'reset' correctly starts u-boot (they'er basically the same) ... then a POR with the reset address set to 0 will behave identically. Better double-check your config in SOPC builder ... or better, your ptf file reset_slave/reset_offset. You might want to try flashing the app at 0 and u-boot 0x40_0000 as well. > I should at least get to main_loop() and see some u-boot prompt before > this happens anyway. Agreed ... that's why I don't think the u-boot entry point is being called at all for POR. BTW: Did you move to Quartus 4.2? Or are you still at 4.1? I haven't installed the upgrade yet ... too close to finishing a job ;-) Regards, --Scott
