My work device use a Sandisk/M-System MDOC H3 chip with PXA270. The device has a mulit layer bootloader to support both Windows CE and Windows Mobile. Due to Windows Mobile need to implement Device UUID feature and MDOC has a hardware UUID funciton. you use “flGetUniqueID()" getting the MDOC UUID, the function in MDOC BDK library.The function on H3 device need more to more time.
if running flGetUniqueID(), can’t use GPIO reset signal to reboot the device.
workaround : Before call flGetUniqueID() to mask GPIO reset function register. after to re-enable the GPIO reset.
