Resolved! Maximum TRACECLK frequency of STM32H725

Hello,I have not found the maximum TRACECLK frequency of the STM32H725 in the documentation. It looks like it is generated by PLL1 with flexible division ratios and thus can attain values that are not realistic for I/Os (100 to 220 MHz for Speed 11 a...

Data transfer from SAI to DTCM using HPDMA not working

I am using a Nucleo-N657X0-Q board to prototype a data collection system that collects samples from an ADC connected to the SAI peripheral and places the results in RAM. If I use CPU AXI RAM0 as the destination this works correctly, but if I change t...
