I am trying to make a custom bootloader, and for that i need to change the flash memory address of the user code (the code which i will upload through the bootloader). So , i made a GPIO Toggle code with no delay, and in the target dialogue box i am changing the IROM1 address to 0x8009000 and also in the linker dialogue i am changing the R/O address to 0x8009000. But after changing the address my code is not working/executing, and i don't know why!
Hello Ronan,
I am changing the storage address of the code(the normal GPIO one) i.e. the address of flash memory from 0x08000000 to 0x08009000 in the project settings. But the code does not execute after the change in address and if i change back the address to 0x08000000 , it starts working.
Sorry for slow reply, I have been on vacation.Again, without knowing more about your setup, it is hard to explain directly. Does the device remap 0x08000000 to 0x0 upon reset?
Regards,
Ronan
