Hi,I try to jump from Bootloader to my main program using this function:void jumpToMainProgram(){ uint32_t topOfStack = (*(uint32_t *)0x8008200ul); HAL_RCC_DeInit(); // deinit clocks // reset all periphals __HAL_RCC_AHB_FORCE_RESET(); __HA...

Hi,I flash a project for debugging and set some breakpoints. Then I compile for release and run the code using the green arrow symbol. The code is flashed, but does not run, as it is stuck in a breakpoint from earlier debug sessions.Is there a way to...

Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...

Hi,I have an stm32l43 connected as a USB device. Using the BOOT0 pin, I can start the built-in Bootloader and use DFU. Now I wish to jump to the BL without this Pin by a software jump.But with this jump, I only seem to reset the device (my code start...

Hi,I my compiler always fails compilation on the first line of stm32l073xx.h, which is totally correct code. stm32l073xx.h:70:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'typedef'I assume there is a syntax error in the file whic...

Hi,I really appreciate your effort. Still as you say... before using this I must understand it fully. I think I am not able to understand this code without learning much more about the internal core structure of the ARM. My problem is, that I don't h...

okay. thanks guys. I thought there would be a simple solution to this. Now I set up a region in RAM for communication between bootloader and main program. for jumping into any part of the program I now just set the command where to jump to and then r...

thanks very much, looks good but much more complicated than I had hoped :D I have to admit I never used ASM so far, so I don't know the meanings of POP and PUSH nor how the core Registers work.where in your example code can I enter the adress where I...

I don't fully understand, how would you do this?

Schmid.M. · 2021-03-22

this is exactly how i do it so far. problem is: if the device is frozen somewhere in the main() due to a software error, the device can not jump anywhere anymore. It would be nice if the jump would still be possible from the interrupt directly.
