Other Parts Discussed in Thread: TPS65930
I'm have having trouble bringing up a new batch of boards. At power up the sys_nreswarm signal is driven out of reset by the OMAP but then in about 7ms it toggles low again for a short time. This repeats continuously. The sys_nreswarm is only connected between the omap and the tps65930 and there is a pushbutton for manual reset. There is a 4.7K pullup on this signal. The voltages all look correct and stable and the fact that it comes out of reset says the omap has checked the voltages, clock, and efuse. I"m not sure what would cause it to drive warmres low again.
I brought up a previous batch of boards (20) without this problem.
Thanks
Steve
