I'm working on both custom board and P-NUCLEO-WB55. Trying to reach the lowest power consumption as possible I just detected that the measured current in STOP2 is around 50uA (BLE off and RTC ON) instead ~2uA. The result is comparable between boards,...

Hi!I'm trying to enable the PDM interface on a STM32WB55RGV with one microphone. Basically i followed the AN5027 application note, but I'm not able to start the clock on the proper GPIO. The configuration from CUBE-MX seems ok, and I checked the reg...

Thanks @Community member. Yes, if I select the PLLSAI1P as the input clock source for the SAI1 Module the peripheral doesn't work, with the PLLP it does. Of course I configured both PLLs to provide the same freq.

Thanks waclawek.jan The issue comes from the RCC, selecting the PLLP clock source instead of PLLSAI1 the PDM peripheral works. It seems an CUBEMX bug generating the RCC config function.

Thank you su much. Here the SAI registers:The RCC :and lastly the GPIOs configuration:PA10 is the SAI_D1 and PA8_SAI1_CK2
