Hello all, I'm designing a num pad using the STMF103 MCUs you can find on the Blue Pill board. However, I am having issues uploading the code to my board via SWD. I get this classic error: Error in initializing ST-LINK device.Reason: (4) No device fo...
Hi Team I have purchased the STM32H7B3I-DK I find that there is no power cable provided,Its just the board that is provided I see that we need to purchse the STLINK V3 , But i see that on the Board it is USBTYPE-B connection for STLINK USB - CN14 ,...
Hello ST community,I think I have damaged the on-board st-link part of the STM32F3Discovery I bought last week. I think I might have slipped and shorted two nearby pins while probing with my multimeter.When connecting to the 'ST-LINK' usb port, the P...
I can program my STM32F746G-DISCO with CubeWorkspace without problem but if I use ST-LINK the same .bin file give this error07:37:27 : Device ID:0x449 07:37:27 : Device flash Size : 1MBytes07:37:27 : Device family :STM32F74x/F75x07:37:38 : File size ...
Good afternoonBefore doing a final PCB design I wanted to test external ST-Link connectivity to the F070 on my Nucleo-F070RB board..So therefore I:Removed SB12 and SB15 (disconnect nRST and SWO)Removed jumpers on CN2Attached external ST-LinkST-Link P...
Board: STM32F746NG Discovery BoardI misinterpreted the Power Supply Jumper JP1 on the STM32F746NG Board. :\ I connected two jumpers on JP1. One that connects 5V_USB_ST_LINK to 5V and another on 5V_USB_HS and 5V.USB-HS-OTG Functions stopped working af...
Is my jumpers in right position. Pls do help. Thanks
Hi, there! :) I've just downloaded the STM32H747I-DISCO MB1248 board design files(https://www.st.com/resource/en/board_manufacturing_specification/mb1248_bdp.zip) I found that the schematics is an Altium Designer Project, but layout is an Allegro brd...
Hello, at the beginning I had STM32G070 (brand new), from the beginning I had a problem with it, ST-LINK utility was connecting with uC, but after a while disconnects it. I was looking in the settings unfortunately I found nothing. Oddly enough, once...
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...
