Hi,as I see it here in my test PCB, the pin PB4 (JNRST for JTAG interface) seems to have an internal weak pullup during reset (I assume 40kOhm as NRST - an external 10kOhm will pull this pin down, but 100kOhm pull down does NOT work...).It is luckily...
Hello.I am building an application and planning on using the STLINK-V3SET to program and debug, but I can not find any reference which describes what pins to connect for the VCP_TX and RX pins from the programming header to the MCU. I believe that I...
Hi everyone,I purchased several boards from Olimex (STM32-E407, STM32-P405, STM32-P407) and I am using the ST toolchain (STM32CubeMX, STM32CubeIDE, ST-LINK/V2, STM32 ST-LINK Utility). The purpose is just to blink a LED.For the boards STM32-E407 and S...
Dear all!!I have a STM32 DISCOVERY DISC-1 and I have a problem. I created .hex file by KeilC and I programed this board by STM32 ST-LINK Utility and everthing seem be OK. But, when I turned off power and after that I turned on, board was not run. I c...
Hi,I have a custom board and am trying to debug live code on the target MCU with STM32CubeIDE but constantly getting the below error. I should note that I'm running Ubuntu 18.04 and have so far been successful in loading my built code with STM32CubeP...
Indeed, I've just bought a brand new Nucleo-F411RE, connect it to my computer and sent a simple program that is doing a printf, so I can see it in the serial monitor ( I'm using MBed studio ).Then I've launched ST-LinkUpgrade.exe clicked on "Connect ...
Hello,i created a custom board which foundamental schematic is like the images:I'm using the classic ST-LINK USB Debugger but i can't debut nor upload my code inside my STM32F767IGT MCU, both with STM32CubeIDE and STM32 ST-Link UTILITY.In the utility...
Hello,e.g. the BOM for the NUCLEO-G474RE does not list CN4, what the manuals call "STDC14/MIPI". It is obvious that is is a 14-pin, 1.27 mm pitch connector with polarization. However having exact specification would help to buy fitting mates.Some s...
Hi,Should NC pins on STM32H753XI TFBGA240+25 be connected to ground, or can they be left floating?Thanks,Thomas
