Using LM Flash Programmer Utility to download code into an LM4F232 devices.. via USB

sherwin tiongson

Hi Guys,

Good day!!

It would really help me a lot if someone can point me to the right direction/documents/procedure regarding downloading my code(.bin) into an LM4F232 devices via USB. Though I already successfull in downloading my code using ROM Boot Loader and LM Flash Programmer Utility via UART interface. In my set-up right now my problem is the LM Flash Programmer Utility cannot detect the LM4F device if I USB DFU.

I would really appreciate all help.

Thanks,

Sherwin

ROM Bootloader for LM4f232 got a bug as per errata.

If you still have problems after using a flash-based version of the USB boot loader (boot_usb), let us know.

Thanks Dave for your reply.. sometime in the future I might need to write a flash based USB bootloader especially that uart is pretty slow .. but for now we might stick into using ROM bootloader and load our code via UART0. Is their a plan to support USB DFU in ROM Boot loader in the future?
