Hi All,After I boot from an epcs device the chip select remains asserted (control register = 0x0000_0400). Has anyone else observed this? --Scott BTW: This causes the u-boot epcs command to fail the first time it is invoked.

Thanks Jesse ...... in general, it's probably good practice from a software point-of-view to assume that the chip select was left in an inappropriate initial state ... ... so it's time for me to use good practice ;-) Thanks again, --Scott

Just an FYI for anyone following this thread:A jump to the reset address (soft reset) when booting from the epcs_controller will cause the epcs boot loader to hang. Prior to doing something like this, you must make sure the
epcs chip select is negated. Regards, --Scott
