About STM32H7 Ethernet again
After re-reading the STM32H7 Ethernet related threads in this forum it seems that most complaints and bug reports are about DMA descriptors and buffers (cache management, allocation etc). At the same time, operations on the descriptors and buffers is...
Hi, is it still possible to use freeRTOS? Regards, Kai
Since ST announced to go with Azure RTOS, does this mean freeRTOS is not longer supported and won't run on ST MCUs anymore? Or does it mean the effort to implement freeRTOS is quite high compared to Azure RTOS, because there won't be any support for ...
Resolved! stm32l431 SWD only connects at 5 kHz
I have a board with an stm32l431rc. I have some sample code generated by CubeMX, and it boots up just fine.I'm trying to work with zephyr v2.5.0. Zephyr has hal and pinctrl dtsi files for this MCU, so adding a new board was pretty straightforward.I s...
