I am trying to program my LPC51U68 via USB MSC. I have followed the instructions here: https://community.nxp.com/t5/LPCXpresso-IDE-FAQs/Creating-an-LPC-valid-image-checksum-directly-in-th... and I have verified that the first 8 words of the binary file sum to zero (ignoring carry out of the high order). I am able to delete the previous image and move the new binary image to the drive window, however when I reboot the new program does not run and the microcontroller appears to re-enter ISP mode.
I am able to program the same image (as a hex file) using FlashMagic and a serial port, so I know the program works.
I am using VS Code, GNU compiler tools.
I must be missing something here. Can you help me? What do you need to see?
