Resolved! STM32U575 programming flash from ST-Link/V2
Hello,I have not been able to program the MCU from ST-Link/V2 (Serial 2-wire) - I suppose this is possible??Bonus info: Debugging with J-link and same (serial 2-wire) works fine.Thanks in advance - Michael
Resolved! How to get back stlink v2-b version? 32F429IDISCOVERY board
After switching to cubeIDE, i was prompted to upgrade the stlink firmware, after doing so the version changed from stlink v2-b to stlink v2 (without the uart functionality)Now i have the v2j40s0 St-link/V2This is on the 32F429IDISCOVERY board.Is it p...
Resolved! ST-Link connect ok for Nucleo_G474RE, but NOT for Nucleo_G491RE
Hi, I really have much exprience with many STM32 products (STM32H7, STM32F4, STM32L, STM32G0, STM32G4).Typically for first board check of new PCB I use ST-Link.I have a weird problem, that my ST-LINK refuses to connect to STM32G491 devices (neither o...
Resolved! STM32H757I-Eval Board w/ External IO Connectors
Hey Guys,So I have this Board and I have a couple of questions:1 - Last week I wanted to connect a sensor to the board, to learn some communication protocol stuff. I noticed that the board PINs (in green) are too close to each other, so, the usual RP...
STM32L151c8t6 PCB design problems
hi we haveseveral boards in need of the stm32L151C8t6 and we have some stock of the mcu in question the problem is that all the pcbs 'from JLCPCB' have this weird issue were the mcu is stuck and i have to manually poke thenrst pin multiple time for i...
Nucleo decoupling for VDDA and VDD
I'm new to STM32 and designing my first STM32F446RE-64 pin PCB. For reference and education, I'm using the Nucleo-64 STM32F446 board, the STMF4 datasheet and the STMF4 getting started with MCU hardware development guide. I have the following questi...
SM32F4 PCR_ON connected to GND
Hi,we have an STM32F27ZI with VDD at 3.6V.We connected by mistake PDR_ON to GND while we drive the NRST with an external voltage monitor as in the picture.reset circuit to NRSTPower upPower downYellow -> 3.6, Purple -> Reset, Green-> PDR_ON In additi...
