Hi Community,Prelude: I soldered my first PCB, added STM32H743ZIT6, decoupling capacitors, BOOT0 switch, NRST with resistor to ground, 5V->3.3V LDO, powered up by USB and 4-pins SWD for debug (PA13/DEBUG_JTMS-SWDIO and PA14/DEBUG_JTCK-SWCLK pins). Ch...

Dear Community,I'm working on STM32H743ZIT6 based project.Here I want to set up 4 ADCs which have SPI interface.On developer's forum is said "If all ADCs will be sampled at the same point in time with the same settings, then the SCLK, CS, and SDI can...

Hi,I'm looking for SRAM memory for STM32H757xI and found thishttps://eu.mouser.com/ProductDetail/ISSI/IS66WVS4M8BLL-104NLI?qs=doiCPypUmgHfByEUFkOsAw%3D%3DDoes such kind or SRAM memory work with this MCU model?Thanks.

After reading documentation carefully, it became obvious, that SCL and IO0 pins on cn9 port of ST-LINK V3 are not used to connect via SWD.Connected grounds of ST-LINK with MCU board and connected T_VCC pins to check voltage.Solved issue with 2.6V vol...

I decreased capacitance and it did not help.

I also followed by experienced engeneer advice, who offered to change 100n to 1u. AI approves that this is not critical and not the cause of failure. I think the reason not in capacitance value.

I will check the article.> Can you connect successfully with CubeProgrammer?I did not try, will try and see.> Is it a genuine ST-Link ?Yes.> Have you tried with NRST connected to the ST-LinkIt is not available with current design (maybe with some tri...
