I want to start writing my own code for the STM32H750 discovery board. I have installed STM32Cube IDE, MX and PROG.
I have downloaded the examples for the board and I'm trying to build and run the GPIO example because its the simplest. I've chosen the BootROM_ExternalSDRAM_InternalSRAM build target and I appear to have built it successfully, although the FLASH memory segment appears to be located at 0xd0000000 which I think is external SDRAM. Is this because I am building a 'debug' configuration? I didn't see any other configurations.
When I try to debug it I get the following:
......
Info : Device: STM32H7xx 2M
Info : flash size probed value 128
Info : STM32H flash size is 128kb, base address is 0x8000000
Error: can't add breakpoint: unknown reason
I don't have any breakpoints set, unless there are automatic ones like entry to main. Is the memory mapping wrong? Is there a set of set-up macros that need to run to configure the clocks, external memory, etc?
When I power cycle the board the original demo application still runs so the internal FLASH has not been changed.
Can anyone recommend a good / better starting point for evaluating the STM32H750 on the STM32H750B-DK? In my target application I have no need for external memory or graphics, I just need internal RAM, and some timers / serial comms / GPIOs.
Thanks in anticipation...
Ian.
