I had some trouble getting the power up completed, this turned out to be an error in the JetsonTX1_OEM_Product_DesignGuide_20170912.pdf
The guide says:
CARRIER_PWR_ON - External 10kΩ pull-up to 3.3V
Doing this will cause that line to never reach logical 1 because the pull up is a pull down until this signal has become 1.
After removing this resistor I have power, I have verified that RESET_OUT# is going high 60ms after 1.8V is stable.
I have also verified that the signal from my terminal on the debug-uart (UART0_RXD) G12 actually comes through.
I have verified that UART0_TXD (H12) and UART0_RTS (G11) stay low during the whole power on sequence, so the strapping should be ok.
Plugging a PC into the micro-USB connector enumerates the TX1, so some code is actually running inside the module.
I don’t see any action from the TX1 module on the UART0_TXD (H12)
What am I missing here.
