Hi,I am using an STM32F746IE controller and in some of them i don't see proper ST programmed values in address locations of BOOT_ADD0 (0x1FFF 0010) and BOOT_ADD1 (0x1FFF 0018). As per the reference manual i understand the ST programmed values in thes...

So here is what I am doing, I am using IAR Systems to build my code and generate .s19 file and using an in-house tool to load the .s19 to device (STM32F469IG), after the download is complete the tool sends Jump command or “Go command” (0x21 0xDE) to ...

Hi @FBL ,I was able to change the BOOT_ADD option bytes with my code, but i wanted to understand why the ST programmed values are not correct in this case? As i have not tampered with the values they should have been in Default values itself. I check...

Hi @FBL ,You mentioned "to access CM4 bootloader", does that mean we have separate internal bootloaders for M7 and M4 cores which will run when we turn on the boot switch and select boot base address? Also I see there are default values mentioned in ...

Hello,I haven't attached any code examples because the same .s19 file when loaded using ST Flash Loader or J-Flash worked, Only when i use a UART communication with our in-house tool to download the code it is unable to jump to the vector table locat...
