HiI created a project from STM32CubeMX for the STM32F767ZI MCU:FreeRTOS 10.2.1 CMSIS v26 tasks (1 main + 5 bus: CAN, 2 x I2C, QuadSPI, USART)1 message queue per task.1 timer to pace the systemuse of DMA and global interrupt active for every bus (CAN ...

HiThe command to download our firmware is as follow (with the option bytes display to show that protection is disabled):STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -ob displ -e all -d C:\Temp\cu.hex -d C:\Temp\data.hex -v -rstThe result always ...

Hi,I attempt to locate information about the firmware in flash. To do so, the data are stored in a dedicated section (called CONTROL_UNIT_SECTION):/** @brief Definition of the firmware info. */ typedef struct firmware_info_t { uint8_t id; ...

I updated the software package for the STM32F1 MCU from the 1.6.0 version to 1.8.0 and I then felt in trouble with the ADC acquisition with the DMA in continuous mode : the data sound to be shifting in the buffer.I read 3 signals (actually RGB LED). ...

In the frame of testing the STM32F7xx MCU, we test the file management capabilities of the STM32F769 Discovery kit. The configuration of the platform to access the SD card has been built with STM32CubeMX (FreeRTOS + FATFS).The code for the test is th...

Found the error : in the xPortPendSVHandler() call, I could observe that the LR register was set to a spurious value (0x00000001) while popping the core registers for the Idle task. From there, it was easy to identify a stack overflow issue.Thanks to...

Forget this. Apologizes

Actually, where is the the "PendSV_Handler" defined ?

I temporarily avoid the hard fault by creating an additional task that is always active (endless loop). This plays the role of the Idle task.What could prevent to use the default Idle task ?

The 2 first points have been checked.Every buffer for DMA is statically allocated.The buffer alignment with 32-bytes boundaries is well observed for large buffer, but not for short ones (e.g. register operation on I2C bus). Is this alignment rule abs...
