Hello, I have a problem with UART on BeagleBone Black. I succeeded to enable UART1 but UART2 asked me a problem and I can do anything on this port. I'm on : Linux beaglebone 4.4.91-ti-r133 I activated firmware with this : (on /boot/uEnv.txt) ###Overide capes with eeprom uboot_overlay_addr0=/lib/firmware/BB-UART1-00A0.dtbo uboot_overlay_addr1=/lib/firmware/BB-UART2-00A0.dtbo ...
and activated everything I needed (all uart and 1 I2C) a little lower in the same file : ##Example v4.1.x cape_disable=bone_capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN cape_enable=bone_capemgr.enable_partno=BB-I2C1,BB-UART4,BB-UART2,BB-UART5,BB-UART3,BB-UART1 Others UART have the same problem... I have also this : debian@beaglebone:/boot$ ls -l /dev/ttyS* crw--w---- 1 root tty 4, 64 Dec 12 15:23 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 Dec 12 15:36 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 Dec 12 15:34 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 Dec 12 15:23 /dev/ttyS3 crw-rw---- 1 root dialout 4, 68 Dec 12 15:23 /dev/ttyS4 crw-rw---- 1 root dialout 4, 69 Dec 12 15:23 /dev/ttyS5 Then all the UART are activated right? But I can't communicate with my device.... and it's work with UART1... Do you have a solution?
