Hi There,I have an extremely weird problem. I have a custom PCB with an STM32F091 chip on it. I am using the SWD interface to connect. I had another board that is the exact same working and connecting perfectly. I now am trying to get this second boa...
Getting stable V-sync and H-sync pulses is critical for clean VGA output. Getting these completely stable on the H743 was difficult and required multiple iterations of different PLL settings. but was possible.On the Nucleo-H7A3ZIQ it has proved compl...
HiThis is the first time I`m using STM32 tools and probably made a mistake hence I can`t connect to Nucleo 68 board.When I try to connect using STLink Utility I receive22:31:40 : Can not connect to target! Please select "Connect Under Reset" ...
Dear STM CommunityI am facing a problem with flashing/erasing STM32H745 microcontroller using STM32-ST Link Utility. Everytime I try to perform any operation I receive popular "Can not connect to target! If you're trying to connect to a low frequency...
Any boot flash is required for this IC, Any standard JTAG pin out and connector part numbers are available.Decoupling capacitor and crystal values are need to verify.
If my board is not powered and the power is provided by the ST-Link, then I can program/erase all the time without issue. However for debugging it is not useful. As soon as I connect the power to the target I loose the connection.Few thingsSWDCLK and...
Hello, I have recently purchased stm32 nucleo-stm32F767ZI board but I am not able to get it to work - I cant debug/program any code for it because internal st link is not detected. Picture of my board:Debug settings:Target settings:ST link schematicI...
Inventek systems ef-wifi module got detached from the board. Hope this is the wifi module. But How can I attach it back to the board. If thats not possible can I get a new replacement the board and how long would that take ? Since its a brand new boa...
I am using an STLINK V3SET and the STLink Utility v4.5.0.0. I have opened up the V3SET and I am measuring at the pins of the connector to the target the correct 3.3V between pins 3 and 5 as indicated in the user manual. This voltage is coming from th...
