As far as I can see the actually set mode is not stored anywhere. One could print it after it was successfully set, but that would be in nand base, not in the atmel driver. > Also I recommend to print the master clock in MHz, and to print the master > clock name/label from ccf driver: > https://github.com/u-boot/u-boot/blob/master/drivers/clk/at91/sama7g5.c#L410 Should be possible. I could do this and send a v2? Greets Alex > > Tested-by: Mihai Sain <mihai.s...@microchip.com> > > Best regards, > Mihai Sain
