Can somebody please advise me working CONFIG_DEBUG_UART _* values for the board? I think I need to obtain some output from the board to debug it further.
Reading arch/arm/dts/am33xx-l4.dtsi isn't as easy to read as I would personally like but 0x44e09000 is UART0 and so forth. Updating doc/board/ti/am335x_evm.rst once you're done with a note about using DEBUG_UART would be appreciated, thanks.
Some notes I have from a previous life which may be useful, but I'm afraid I've no way of checking these days:
- CONFIG_DEBUG_UART=y
- CONFIG_DEBUG_UART_BASE=0x44e09000
- CONFIG_DEBUG_UART_CLOCK=48000000
- CONFIG_DEBUG_UART_OMAP=y
- CONFIG_DEBUG_UART_SHIFT=2
- CONFIG_DEBUG_UART_BOARD_INIT=y
- CONFIG_DEBUG_UART_ANNOUNCE=y
Thanks. Unfortunately, these don't work.
Ok. The settings were working before 0dba4586 ("arm: Init the debug UART")
