Hi Experts, Are UARTs available on Apollo Lake different than traditional 8250 UART? Or any specific settings (jumper etc) required to use them?
Problem Statement: I am using UART available (through micro USB port) on Leafhill CRB. I am able to get coreboot logs but grub fails to detect these uart. I have following in my grub2.cfg serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1 Grub output an error serial port COM0 not found If I change --unit=0 to 1 or 2 grub2 reports similar error serial port COM1 not found serial port COM2 not found
