If I do a SetMux for I2C1 SDA off of GPIO_SD_B1_05 the XPRESSO/JLINK debug locks up. If I use AD_B1_01, there is no problem. If I single step, it then seems to jump over instructions and loop back over itself, so the debugger seems to be corrupted at that point.

I also tried just to add a SetPinMux for SD_B1_05 to the flexspi_nor test software that was working and it now fails also. Moving to AD_B1_01 seems to work fine for the SDA signal but I will have to juggle board wiring as I am short GPIOs if I cannot use that one for some reason. Setting SD_B1_05 to SDA or plain GPI use does not matter, it causes problems anyway. Is there something special about this pin??
