FIXED, I think.
The problem was on my end with the typos, but anyways, here is what I did to fix it.
I enabled BB-UART2 in my uEnv.txt file using commands given by qxn.c.
nano /boot/uEnv.txt
Add in the following:
#for v4.1.x
cape_enable=bone_capemgr.enable_partno=BB-UART2
#for v3.8.x
cape_enable=capemgr.enable_partno=BB-UART2
Next, check to see if it has been added by using the following:
(THIS IS THE LETTER ‘O’ NOT THE NUMBER ‘0’ WHICH WAS MY MISTAKE)
ls -l /dev/ttyO*
Output should show:
/dev/ttyO0
/dev/ttyO2
Then just went back to following the main instruction of flashing the firmware by going to the directory and using:
make flash_firmware.
Hope this helps others having the similar problem. Thanks for the help other forum users.
