Dear sir
Ibm using bbb rev.c with the lastest image with debian 9.5
Before i was using the version 9.3
With the same /boot/uEnv.txt the serial port uart1,2,4,5 are not working.
Do you have any idea or suggest?
Thanks, Nicola

Hello,
Are you setting your config-pin utility to state out the necessary pins in their respective modes? For example: sudo config-pin P9.21 uart && config-pin P9.22 uart.

P.S. This might help w/ your default config. if you have already updated your bootloader on the eMMC.
