I'm working on an application that requires Ethernet on an STM32F765 chip and there are two options to attach an Ethernet PHY to the MCU: RMII and MII. Deciding on which interface to use has led me to a post that mentioned RMII having issues on STM32...

I'm using a timer as a 1ms timebase, which is configured right after hitting main, so very early. I use this timebase to implement timeout functionality in my drivers as I prefer to not just use while loops when waiting for something to complete.What...

STM32G4 devices are split into 2 flash categories per the datasheet: Category 2 devices (STM32G43x/G44x) which have only single-bank capable flash with a capacity up to 128kB and Category 3 devices which are dual-bank capable and have up to 512kB of ...

Thanks for the reply. I figured that the issue was not related to hardware, but unless one aspires to write their own Ethernet driver, you're stuck with the HAL. In that case, would it be advisable to use MII?Or have the bugs been fixed? The post I r...

Well, I posted this prematurely... Did some more googling and found a similar post that had the solution:https://community.st.com/s/question/0D50X00009Xki8ySAB/stm32f051-tim2-counting-way-too-fastA timer's prescaler is taken into account after an upd...

Could you elaborate on this a bit more?With "size of the flash array tested" do you mean this is a "test report"? How can this help in finding the page size? I thought I looked through the datasheet pretty carefully, but I couldn't find anything rela...

Ha, you hit the jackpot! The DBGMCU_IDCODE register is exactly what I was looking for. In fact, for the G4 series, there are only 2 values (IDs) mentioned. One for each category. I totally forgot that about the IDCODE reg, so thank you for the remind...
