Hi，
Did your BBB boot with the latest system image from BeagleBone forum?
If so, you have to enable the Serial port 2. It was not enabled by default.
To enable serial port 2, add a line with “cape_enable=bone_capemgr.enable_partno=BB-UART2” to /boot/uEnv.txt and reboot your device. Change the port back to dev/ttyO2 in flasher file.

Hope this can solve your problem, Let me know if further detail/explanation would be helpful.

Hello,

Thanks for the reply. I have tried adding it into the uEnv.txt file as you said, but still no luck in using “make flash_firmware”. I have added my output errors if they will help you understand my current situation. My Linux info is as follows: Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:56 UTC 2015 armv7l GNU/Linux

EDIT (May 4th, 2016): I noticed a typo in enabling the Serial Port 2 with BB_UART2 and have now changed it to BB-UART2, but still can’t get it to work. I have tried both formats for 3.8 and 4.1 for enabling the Serial Port 2.

Thanks again in advance,
Alvin
