Hey there!I've been playing around with the Ethernet HAL driver on the NUCLEO-H563ZI and I was able to make it work. I'm currently using the latest STM32CubeH5 package release. Here's the issue: whenever I receive an ethernet packet, the interrupt at...

Hello there!I'm reading the STM32H5 documentation on how to setup the ETH descriptors correctly. At the same time I'm following the HAL for the same H5 series.When the RX descriptors are initialized, I can see the HAL assumes there are 4 descriptors....

Hello there!I've been setting up the UART peripheral on my STM32H5 and everything works great! However, there is one thing I can't completely understand:Using an RTOS to call HAL_UART_Transmit or HAL_UART_Transmit_IT, what's the advantage of one over...

Hello there!I've been tinkering around with the STM32H5 and recently I've managed to setup the STM32H563 with SPI and DMA.I'm now trying to understand what is the limit of the burst (either source or destination). I'm using the DMA channel 4 (with a...

After a brief discussion with one of my colleagues, we reached the conclusion this might have been caused by the second buffer of the descriptor. Since every description (read format) has two buffer addresses but the HAL only populates one, the DMA m...

After further investigation I noticed the error happens even before HAL_ETH_ReadData is called.1. HAL_ETH_Start_IT is called2. Interrupt happens and triggers HAL_ETH_RxCpltCallback and then HAL_ETH_ErrorCallback with the error 0x4480 or 0x4080 (on th...

I'm having a similar issue on the STM32H5. The application works but I get a RBU all the time

Thanks for the quick reply!Would that advantage also apply when the HAL function is called from an RTOS?

Blocking vs non-blocking UART using an RTOS

STM32H5 DMA Source burst length vs HAL_SPI_Receive_DMA `Size` argument.
