This patch should only give the basis for its use.
I use it in one of my Netstal boards MCU25. Patch will come soon, as I am
cleaning
them up at the moment. But the relevant snippet is here:
board/netstal/mcu25/mcu25.c
void vxworks_preboot(void) {
if (sys_install_requested())
mtdcr(CPC0_CR1, CPCO_CR1_USE_EXTERNAL);
}
Is this okay for you? Or do you have more questions?
