Hardware used:
STM32H747I-DISC0 Discovery kit (MB1248-H747I-D02 / A191001982)
Tools used:
STM32CubeProgrammer v2.4.0.
STM32CubeIDE v1.3.1 for code generation
(gnu-tools-for-stm32.7-2018-q2-update_1.0.0.201904181610)
STM32CubeProgrammer gives me an error when I try to program M4 using embedded bootloader. I have no problem programming M7 similarly.
Error:
13:35:23 : Error: Data mismatch found at address 0x08100040 (byte = 0xFF instead of 0xAD)
13:35:23 : Error: Download verification failed
I follow the steps below to access embedded bootloader:
1- Program option bytes on application code(M7) - ( I’m just update BOOT_CM7_ADD0 = 0x1FF0 )
2- Power Off -> Power On
3- Connect the embbeded bootlaoder (After push the Reset Push-Button(B1) Why?? )
