+1 on using starter-ware as a reference for low-level configuration, but with any luck you won't have to dig that deep into the guts of things. The U-Boot code is already doing low-level hardware configuration, you just need to tweak things a bit. There are already functions available to setup the various UARTs and I2C. I think you should be able to modify the SPL code (which is trying to read the EEPROM and properly setup the SDRAM, among other things) to provide some externally visible output. NOTE: Since your board is based on the Octavio part, at least you don't have to worry about the DRAM bus timings or trace routes being messed up. I think if you can get your code running (double-check all boot mode pins) and hard-code the EEPROM auto-detect, you should be able to get running. #FingersCrossed -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Hey said he wasn't sure which parts were used he had no input on hardware which is bad news.All my comments are based on if the HW guy rolled his own board trying to keep things cheap that's the worst case.If he used standard parts he could fake out the boot code. The problem is it sounded like there is no eeprom if that's true the HW guy is cutting corners. I've yet to see a HW guy worry about software porting issues after all they say SW is free. I've also never saw a manager who was behind schedule Not minimize the board support and bring up he's gonna say what's the problem. Hopefully I'm wrong. I always ask these questions in an interview. If I'm right he's gonna be the scape goat for the schedule and that's O.K. if your 80 hours a week is paid😊 -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
