Hello!
Recently I found out that GPMCWrAccessAndWrDataOnADMUXBusTimingConfig function in GPMC driver does not work. Function applies timing values by simple OR-ing and this is wrong due to non-zero reset value of register GPMC_CONFIG6_i.
I use StarterWare 2.00.01.01. Please fix this issue in next release. Patch is attached.
