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 0x8000000Load 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?ThanksTarun #stm32f4 #eeprom #discovery #flash #stm32f #rewrite #tags-are-pointless2014-12-09 04:05 AM
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.2014-12-11 03:27 AM
Thanks for replying. I erased flash with STM32 ST-LINK Utility software and then tried to load and It works...!!
