I’ve spent several days on this with various levels of success, but nothing satisfactory.
I can compile u-boot and I can install u-boot on my Jetson-TK1
I have a device plugged into the serial port, it is constantly sending update information the moment it comes on, this traffic on the serial port causes U-Boot to pause. I’ve tried many of the u-boot arguments in the various ‘configuration’ files - I’ve even tried disabling console completely, but nothing is working so far. Even with CONFIG_BOOT_DELAY=0, anything connected to the serial port halts booting.
I am either missing the magic configuration parameter or I need to configure U-Boot to use the second serial port on the Jetson, however I don’t know how to configure U-Boot to access the second serial port.
Again - I’m not asking for silent mode - I can achieve that, I need it to boot even when data is coming over the console port.
Thanks for your time,
