To resolve the issue, I have added the proper pinctrl signals for the uart,
I did this for uart0 & uart1
uart1_pins: pinmux_uart1_pins {
pinctrl-single,pins = <
0x170 0x30 /* (E15) uart0_rxd.uart0_rxd, PIN_INPUT |
MUX_MODE0 */
0x174 0x00 /* (E16)
Robert,
Yes, it is correctly passed to the kernel:
ubuntu@ubuntu-armhf:~$ cat /proc/cmdline
console=ttyO0,115200n8 fixrtc
capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN root=/dev/mmcblk0p2
ro rootfstype=ext4 rootwait
Best regards,
Phil

Hi again,
I decided to look through the /proc/iomem pseudo-file to see if the mapping
looked reasonable. I believe the kernel may be corrupted since there is
garbage in the map for the usb:
ubuntu@arm-hf:~$ cat /proc/iomem
44e07000-44e07fff : /ocp/gpio@44e07000
44e07000-44e07fff :

Hi,
On my BBB I have a Serial RS-232 BeagleBone Cape (BB_BONE_SERL-03 Rev A1)
that I have jumpered for UART4. It works under Angstrom and was recently
working under Ubuntu 12.04 LTS. Now it is not working under Ubuntu.
ubuntu@ubuntu-armhf:~$ cat /boot/uboot/uEnv.txt
optargs=fixrtc capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
