STM32MP1 support available in SW4STM32

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4; you can download a short video showcasing this on the ac6-tools website (registration required).

STM32F4 HAL Driver Callbacks

France

Hi Matt,

Yes, the HAL CAN Callback is called in an ISR context and should

  1. be kept short
  2. only call fromISR FreeRTOS functions

Generating various events from the ISR (using xQueueSendFromISR) is fine but calling back the HAL CAN driver to send data is probably too much (and may even be a source of race conditions...) so this should be defered to some (possibly high priority) task.
