Well, I'm trying to communicate with the chip thru the I2C switch(TCA9548a) on the PS side. From the schematic for the N310, I'm missing how the FPGA could be involved here since I'm trying to accomplish this on the PS side. Maybe I'm missing something here.

Is there anyway possible that mpm is still being started at bootup? On What does ps |grep usrp Yield? OK, so it isn't usrp-hwd that is "holding" it. That chip on the DB controls signals like "PWRGOOD", it's possible that the FPGA itself is logically "holding" that interface, but that's just total speculation on my part. If the "lsof" utility were installed, it would be easy to see if some app-layer process had it open. But this system image doesn't include "lsof".
