UM1974 Rev 10, Table 1. Ordering information:For the NUCLEO-F303ZE board the column "Differentiating features" lists an "Ethernet", which is false.Of course a deceptive photo and description just adds to the confusion...https://www.st.com/en/evaluati...

Every day some alternatively gifted user creates a duplicate topics, people often comment on more than one of those and in the end the information is scattered in around and is a mess. For an example:https://community.st.com/t5/stm32-mcus-embedded-so...

The FLASH I-cache on G4 is 1 KB, while the CPU I-cache on H5 is 8 KB and works also for SRAM and external memories. The FLASH prefetch is clearly explained in the RM0481 section 7.3.4. It's impact on performance is not so significant as from the I-ca...

What I said was based on the observation how the old ST code with a broken ethernetif_input() function worked. The Rx packets were piling up in the DMA queue, because the code was not processing those. But it could also be anything from the million i...

Your network input processing code assumes that one Rx interrupt means one Rx frame to process, but that is not true.And also read this:https://community.st.com/t5/stm32-mcus-embedded-software/how-to-make-ethernet-and-lwip-working-on-stm32/m-p/261456

If a 10-20k pot is fine as a voltage divider, then obviously MCU output doesn't need additional buffering.

So by far the most liked topic in 2023 is about the bull excrement (the "enjoyable cohesive experience"), which ST forced on users... Congratulations!But, hey, let's look at what other significant achievements the Cube/HAL team did in 2023:Released t...
