STM32N657 RMII Ethernet — RX sampling phase latched wrong at MAC reset (reproducible in PHY loopback)

Hi, We're hitting intermittent Ethernet RX corruption on the STM32N657 in RMII mode with a LAN8742 PHY. On some cold boots the receive path is broken for the whole session: the MAC flags incoming frames with the dribble bit (RDES3.DE) and error su

Need ability to cancel debug session on connection failure.

When the connection fails “unexpectedly”, CubeIDE keeps re-trying for a long time: Although “unexpected” to the IDE, the reason may be obvious to the user - so it would be useful to be able to cancel these retries, exit the Debug Session, and return

Please prioritize Code in the editor pane's menu

In the editor pane’s menu row, the icon to enter Code is hidden under “...”. As it’s one of the most used things here, please change it with something else, e.g. the smileys (which are entirely unneeded in a technical forum), or the 3 line alighment

N6 VENC causes I2C slave issues

Hi all, Experiencing yet another hurdle using the STM32N6: I am running into the issue where if I run the VENC as the JPEG encoder, where I previously found out how to properly run it in the first place, I get issues in the I2C slave communication…!
