I am still seeing the problem (even on the next branch). This definitely seems to be caused by the processor boot ROM. > Has anyone found a smoking gun inside U-Boot or will we have to wait for Calao to make boards with the RTC on a different chip select? I believe a hardware change is the only way to fix this problem. Regards, Stephen
