HI
I was using ST32 Cube Programmer, ST-Link v3, and target board well.
However, the following error suddenly occurred.
(The target board also continues to operate normally)
Symptom-1) The settings are the same, but the DEV_Target_Held_Under_Reset error suddenly occurred.
The configuration was operating normally, and even after changing all the things that could be changed, such as the target board, cable, and PC, the error below continued to occur.
Symptom-2) When I changed the mode to Hot Plug, the connection was made, but a data read failed error occurred.
Since the data read failed error occurred, I could not perform any functions such as download and erase.
Others
- ST-Link v3 update works fine in cube programmer.
- I tried downloading with ST-Link v2, which has a spare target board with the above problem, and it worked fine.
I wonder if ST-Link v3 is broken?
At first, I thought so, but ST-Link v3 was updated and the mode was changed, so it was connected, so I wonder if it is really broken.
