Resolved! Custom Bootloader Testing & Debug
I am trying to write a custom bootloader. I have compiled both bootloader and application binaries and concatenated them in the makefile. When I flash the device with the binary (via ST-Link) my application is not booting up.1) I suspect the issue is...
STM32F0 bxCan Interrupts (new documentation?)
Hi,I'm going around Can communication using interrupt and HAL drivers. I have successfully configured CAN of my STM32F0 device using CubeMX. I can handle Transmit and Reception. Now I'd rather to have reception handled by interrupts, but it seems to...
SD Card sector read delay
I am making an stm32 driven music player that reads from a text file containing binary PCM data. (not the right way to do it i know but it gets the job done) I did a test by doing an f_read 1 byte at a time at the sample frequency (44100) to see if t...

Hi,I'm trying to get PTP timestamp on STM32H743 Nucleo board. There is no proble with LwIP and ethernet driver so far except for PTP. I followed the instruction( 58.9.7 Programming guidelines for IEEE 1588 timestamping) on reference manual (RM0433) a...
External interrupt not working when ran by secondary bootloader
Custom board based on STM32F030C8, application compiled with Keil. Using the HAL for initialization and runtime.When compiled to run directly out of the flash, the EXTI for PB0 works. It is configured to generate interrupts for both edges and when th...
software start of boot loader in the dual core processors STM32H7x[5,7]?
Hi!How can we correctly start the internal bootloader from running code, as shown herehttps://community.st.com/s/article/STM32H7-bootloader-jump-from-applicationbut in the DUAL CORE controllers (STM32H7x[5,7])?I have used the code and STM32Prg can "c...
