Other Parts Discussed in Thread: UNIFLASH, EK-TM4C1294XL, DK-TM4C129X
I have searched a lot lately but I found always the same answer that TI does not have a demo project or example for an USB Bootloader with TI-RTOS.
I have a TM4C1290NCZAD on a custom board and I would like to update it`s Firmware during runtime. I am using the TI-RTOS on it.
I tried the built in bootloader with the DFUProg provided by TI. If I erease the Flash with Uniflash first then I can update the Firmware of the empty microcontroller.
But I would also like to be able to update it when the Firmware is already running on it. I used the "boot_demo_usb" project from TI. That one is also working fine
and it does the update during runtime but it does not have the TI-RTOS. I tried to eliminate all the code parts regarding the touch screen and mouse and everything
which I dont have anyways and put the remaining code in to a TI-RTOS project but sofar I had no success. Is there anyone who already tried something similar,
or could anyone give me an example maybe? Or is there a reason why TI does not have an example like this?
If you could give me any tipps or ideas how to try it I would be really greatful for that.
Thank you very much in advance!
