I followed the hardware manual "TWR-LS1021A Reference Manual" section 5.3 "CMSIS-DAP debug support", however I cannot download the firmware described in that section,
1 Download the CMSIS-DAP firmware and documentation from http://compass.freescale.net/livelink/livelink?func=ll&objId=232410365&objAction=browse&viewType=1
So I want to switching back the mode, that is switching the usb port back to serial-to-usb mode. However, the board has no response even if I plug it to PC.The D2 LED is turned off after pluging. I cannot find answer form manual, so I have to ask for help from Freescale.
Thanks and Merry Christmas!
