Question

Error while firmware loading

Hello all

I am working on STM32F4 Discovery board. I loaded a firmware on my board and it worked fine. Now I want to load new firmware which must be overwritten on previous one. When I load it says

''Loading Section .isr_vector, size 0x2724 lma 0x8000000

Load failed''.

Do I need to reset board configuration in some way.? or do I need to erase previous firmware first? or is there any other action which must be applied before this operation?

Thanks

Tarun

Not sure what tools you're using, or what settings the ST-LINK has.

Try ''Connect Under Reset'', SWD mode, or pull BOOT0 High to defeat issues were user code is breaking SWD/JTAG connectivity. Erase the user code and start over.

Only SWD mode is supported. You can break the SWD interface in several ways in your code, low-power modes, reconfiguring the GPIO pins, etc. Try to avoid those.
