I have a GPS connected to uart0, and the input stream is interrupting the syslinux boot process when I get to the prompt regarding the kernel choice.
switch to partitions #0, OK mmc1 is current device Scanning mmc 1:1... switch to partitions #0, OK mmc0(part 0) is current device Scanning mmc 0:1... Found /boot/extlinux/extlinux.conf Retrieving file: /boot/extlinux/extlinux.conf 221 bytes read in 160 ms (1000 Bytes/s) p2771-0000 eMMC boot options 1: primary kernel Enter choice: 1
I need to get rid of the prompt which asks which kernel I want. The data from the GPS is streaming over that rx pin, and the boot sequence thinks I’m asking it to interrupt things. I’ve tried a number of options in /boot/extlinux/extlinux.conf, but nothing has worked so far.
I would really appreciate it if anyone had a suggestion. Thank you!
