Hi everyone,
I’m currently facing an issue related to bootloaders and FreeRTOS on STM32 microcontrollers, specifically the STM32H735 and STM32H730.
Here’s the background:
STM32H735 Development Board: I have successfully implemented a bootloader that jumps to an application stored in external flash memory. This setup works perfectly with FreeRTOS. In order to ensure that the jump worked correctly, I had to explicitly disable FreeRTOS-related interrupts before performing the jump:
// Disable FreeRTOS interrupts
taskENTER_CRITICAL();
portDISABLE_INTERRUPTS();
After adding these lines, the jump to the external application works without any issues on the STM32H735.
STM32H730 Custom Board: Here's where the problem arises. I'm working on a separate project using an STM32H730 microcontroller. The bootloader can successfully jump to the external flash application when FreeRTOS is not involved. However, when I introduce FreeRTOS, the system fails to jump correctly, even if I use the same approach as I did on the STM32H735.
My question is: Has anyone experienced this kind of discrepancy between different STM32H7 microcontrollers when using FreeRTOS and attempting to perform a jump to external flash? Is there something specific to the STM32H730 that might be causing this issue?
I’d appreciate any advice, suggestions, or insights you might have. Thanks in advance!
