I made a tx1 carrier board myself.and When I use my self-made board with tx1 core boad, the jetson tx1 can not boot.
I measured the voltage, included Vin 19V, 5v_sys, 3v3_sys, 3v3_slip and the 12v_sip, and all those voltage are correct. Also I measured the boot pin voltage at initial time, and those are correct.
But I found that the power monitor I2C bus is about 2.2v, not 3.3v.-- when use the nv carrier board, the monitor I2C bus is 2.2v for a while and later change to 3.3v, this is a diffierent.
Below is the uart log, the tx1 stopped at the final and never change latter.
