STM32CubeProgrammer cannot connect with STLINK-V3SET.

[kiichi]

Hello

I detect (regular) ST-LINK v32 with STM2CubeProgrammer, but it remains not connectrd.

Please tell me what is the problem and how to fix this problem. ?

Hello @kiichi ,

Try Connect mode: Under reset.

from my experience this happens if

a. connection is bad (bad contact or long wires)

b. spikes from mains coming in ; if you supply target not from USB (where stlink is also) your connection is prone to catch inductive or capacitive coupled spikes from mains;

i had exactly this behavior here at my PC . "connection lost" every some minutes or an hour.

then plugged in mains -> target supply at the PCs (filtered) master-slave socket strip and cable routed near usb-cable to target; target has mains filter and mains earth also; now debug can run many hours without any problem.(and still 2,5m away from PC , stlinkV3 -target cable about 20cm long, at full speed 24MHz + 16Mhz SWO)

try this.

Hello @kiichi,

Thanks for your feedback,

STM32CubeProgrammer does not support SWD/J-TAG with MPUs. However, with STM32CubeIDE, you can connect and debug your MPU.

For MPUs, only USB and UART interfaces are supported in STM32CubeProgrammer.

Thank you for the advice.
I will check the connection with STM32CubeIDE. thank you.

I have a question.
When using STM32CubeProgrammer, it was possible to connect STM32MP157F-EV1 with USB-OTG and write to eMMC of STM32MP157F-EV1.
However, STM32CubeProgrammer could not connect with SWD/J-TAG.
Is it possible to connect with SWD/J-TAG with STM32CubeIDE and write to eMMC?
Kiichi.
