Has there been any resolution on this? From what I can see (with scope and logic analyzer) the RTC seems to be corrupted by the DataFlash boot code built into the chip. [The Calao board doesn't have the DataFlash memory and used the chip select for its RTC instead...] 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?
