Resolved! STM32H573V ETH_DMAMR.SWR stuck

I have designed a board with a STM32H573 and a KSZ8081RNACA PHY. As soon as I enable ETH clocks the ETH_DMAMR:SWR bit gets set.Verified:1. The 50 MHz clock from the PHY is present and stable (oscilloscope) at PA12. GPIO PA1 is configured for AF11, NO...

STM32C011D6Y ADC input pin power consumption

Hi all,I'm working on a very low power custom board powered by a STM32C011D6Y micro controller. I must read an ADC input routed to F1 ball (PA3, PA4, PA5 or PA6) but I'm measuring some strange power consumption related to the input voltage on the pin...

Resolved! USART receiver timeout after a (LIN) BREAK?

Hi there,I am using the full featured USART in LIN mode. The start of a LIN packet is signaled by a BREAK condition. The next byte is the SYNC (0x55). After the BREAK is detected, I enable the receiver timeout so that if the SYNC (0x55) is not receiv...
