Resolved! 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...

STM32N6 power supply simplification

I am working on an STM32N6 hardware design, and have reviewed both development kit reference designs (MB1939/MB1940). Both designs use the same power supply scheme, when using internal SMPS it has 2x 3V3 regulators and 3x 1V8 regulators.I am interest...

Resolved! RCC_CR.HSEBYP not reset by Software Reset

Experimenting with STM32F427 and STM32F446 I found out, that the RCC_CR.HSEBYP bit is *not* reset by Software reset. It is reset only by NRST and Power-On reset.While applications where this could lead to problems (i.e. where HSE clock source is chan...
