In thread started by me, can't mark post as "Answer" - maybe because it's from before the migration?

I’ve started a thread before the migration. Now as it received the best answer, I would like to close it by marking that answer, but I can’t as the appropriate item is missing from the posts’ menu.To exclude some potential issue with this incarnation

I got error when I'm using the STM32CubeProgrammer with MCU of STM32N657

hi guys I need to put a F/W program on my board that my coworker made but there’s a problem with CN6 so I have to use TAGand I can’t use USE port for power so I can use only VIN when I was using the STM32CubeProgrammer then I got this error I chang

The Cortex-M7 debug and trace/debug subsystem registers do not appear in the SFRs.

I need to view all Cortex-M7 debug and trace/debug subsystem registers during debugging—similar to how peripherals like DAV, RCC, and GPIO are displayed—but they do not appear in the SFRs list; specifically, I need to view the ITM, ETM, WDT, and SWO

STM32L4, voltage breakdown on high-impedance ADC input after MX_ADCx_Init

Hello everyone,I measure a voltage on a STM32L496 using the internal ADC and found the following issue:Setup:The voltage is scaled down via a high-impedance voltage divider (2 x 470kOhm). To avoid distortion by sampling, the voltage divider has a 100

Can ST please quantify waitstates imposed by accessing ETH registers

ETH is obviously a dual-clock peripheral, and some of the registers are most probably behind a synchronizer, in the MII clock domain. It’s not unlikely that reading some of those registers imposes waitstates. Writing may not, but then those are subje

STUSB4500QTR: does powering VSYS disable VBUS monitoring?

Hi, I'm designing the STUSB4500QTR into a board that can run from USB-C, PoE or a DC jack. VDD is on VBUS as usual, and I'd like to run VSYS (pin 22) from our 3.3 V supply instead of grounding it, so the part can't hold the shared I2C bus low when th

STM32U5G9 – 90° rotated display without a second framebuffer (LTDC / GFXMMU / GPU2D)

Hi,We’re using an STM32U5G9 with a MIPI DSI panel (driven by the LTDC through the DSI host). The panel is 800×600 and scans in landscape, but it’s mounted rotated, so the user sees a 600×800 portrait image. The panel controller can’t swap its scan di
