Hello, After having trouble with my iBOBs becoming unresponsive to everything other than the PROG button, I am considering using a digital IO device to remotely toggle the PROG signal. I notice there is a header labeled J1 on the board near the PROG button. Is this indeed connected to PROG? I looked in the iBOB schematics, but the actual part numbers on the silkscreen do not seem to show up in the schematics, but it does look like such a PROG header exists. Just want to make sure. Has anyone used this header before? Any advice about doing so? I am thinking of using either an open collector driver or an opto isolator to ensure no high voltages are unintentionally connected to the iBOB.
I am still having trouble coming to grips with the fact that when the iBOB becomes unresponsive, it is still possible to program it using iMPACT and read back the status register showing that there was no CRC error and programming completed successfully, yet the PowerPC is completely unaccessible via Ethernet or RS232. After reading through the datasheets, it does not seem like this should be possible. I would suspect some hardware problem, except both iBOBs behave the same and both run fine once they are reset. Is there some sort of race condition between the PowerPC clock and the ADC clock that could cause this? Glenn
