I keep getting this error every time I reset or do a flash.sh load and boot to the TX2 :
bootconsole [uart0] disabled.
I have a serial connection from the host (Ubuntu 14.04) using J21 GPIO header pins 8, 10, 9, 10, 11, & 36. These are, respectively, UART0_TX, GND, UART0_RX, UART0_RTS, and UART0_CTS (according to the pinout chart). I’m confused about whether this is really UART0 or one of the other 6 UARTs (I’m not really sure how you select a specific UART.)
If it is UART0, that would seem to explain the hang error above because I’m using the same port (UART0) for concurrent serial comm and booting (bootconsole?) operations. Is there any way to specify which UART you want to use for booting?
Can I use the 8-pin serial connector (I think I read this is considered UART1) for either booting or serial comm? This would avoid whatever arbitration might have to occur in the above scenario. And, if so, how do I enable this?
