Hi, I've been working on a Beaglebone Green Wireless for a few weeks and have been using USB FTDI for serial communication. I now need to use the onboard UART1, UART2 and UART4.
I have been googling and reading through all the topics on the Forum and ended up wrecking my image twice so I really need help. I'm using the latest *bone-debian-9.5-iot-armhf-2018-10-07-4gb.img * When I try using *config-pin 911 uart* I get a message that P9_11 pinmux file not found. Pin has no cape: P9_11 I have also tried updating the uEnv file with the following cape_enable=bone_capemgr.enable_partno=BB-UART1 This caused my BBG to throw errors on boot and I wasn't able to access the device After a rebuild I made the above change to uEnv.txt and then added the overlays but on boot I got errors that they could not be loaded. ###Overide capes with eeprom uboot_overlay_addr0=/lib/firmware/BB-UART1-00A0.dtbo uboot_overlay_addr1=/lib/firmware/BB-UART2-00A0.dtbo uboot_overlay_addr2=/lib/firmware/BB-UART4-00A0.dtbo What is the current recommended method to configure UART on a beaglebone from scratch and one that will persist between restarts? Thanks in advance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
