RM0091 interrupt priority > 4

in RM0091 I found Table36 which defines priorities > 4 (I believe that for CortexM0 maximum interrupt priority = 3). Does anyone know what these numbers are?

enable can interrupt missing in STM32CUBEIDE

In every guide I see (e.g. https://www.dailyduino.com/index.php/2020/06/01/stm32-can-bus/) it states that I need to enable can interrupts by going (on the ioc) to pinout and configuration-> connectivity -> CAN -> NVIC Settings -> enable can…

STM32F030x sends ST20033000022056000063227OV every 5 seconds and cannot be programmed

I built 2 baremetal development boards, both using the STM32F030K6T6. The MCU on one board can be programmed as indicated in the datasheet using the boot pin selection and via USART pins PA14 and PA15. The second does not respond to flashing command…

STM32F0. How do I assign values from variables in RAM to a separate variable?

I am doing a project on a bootloader for an STM32F051, which jumps to an application in a different memory location. This part works fine. The issue I'm having is that I've defined a location in FLASH to place variables for the Application. These…

Consumption of SRAM for cortex-M3 and cortex-M7

I migrate from M3 to M7. M3 used STM32F103VE and has 64 KB of SRAM. The M7 is STM32F746ZG and it has 240KB of SRAM. I moved most of the M3 code to M7. Additional LWIP is being used for the Ethernet function in M7. But I found that heap memory was…

Place bootloader after the Application in Flash Memory

I wrote a Bootloader for my STM32F042k6 board that functions pretty well. On System Reset the Bootloader is launched and can later jump to the Application. That was great:). Now I wish to do the opposite in my Flash. I wish Launch my Bootloader at a…
