Cannot import variables in STM Studio. Error opening ST-Link connection.
Hello All,I am hoping to reach out to the community for help with an error that I am experiencing with STM Studio. I recently installed STM Studio, part #: STM-STUDIO-STM32, version: 3.6.0.When I try to import a variable to view I get an error messag...
Resolved! ST-Link/V2 cannot detect STM32 target
I have bought a new ST-Link/V2 from Digikey a while back and have only recently gotten the chance to use it. But every time I try uploading code to my geniune WeAct F411CEU6 board using SWD I get the error code "Error: No STM32 target found!". I don...
Resolved! Extremely high current draw in L031K6T7
I'm running into an issue while designing a relatively simple custom board with an L031K6T7, where after programming it the current draw exceeds 200mA and eventually breaks to the current limit of the power supply at 800mA.When I assemble the board t...

Resolved! USB-UART stability issues over STLINK when "Mass Storage" type enabled on MACOS
I've found that Nucleo-L4R5ZI and Nucleo-L476RG sometimes stop receiving UART data through the STLINK USB interface is Mass Storage type is enabled.I created a program that echos random data sizes (send to board, board echos back). This will crash af...
