BBB - error: ‘RTC_OSC’ undeclared (first use in this function)

[bbros-dev]

I'm following:
https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black

I've patched successfuly (a git library command peculiarity meant git was checking out master instead of 2019.04 when I reported issue #11).

However, I now encounter the following error:

$ make ARCH=arm CROSS_COMPILE=${CC}

<snip>

  sys_rtc_osc = readl(RTC_OSC);

The following patch appears to workaround this issue.

I have no idea if this is the most appropriate place to move this definition.

HTH?

Odd as it's defined here:

https://github.com/eewiki/u-boot-patches/blob/master/v2019.04/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch#L23-L34

Yes, I left that there, and copied it to ./include/configs/am335x_evm.h. After that I've been able to build.
