STM32CubeIDE can't connect (No device found on target)

Hcorw.1 · ‎2021-12-02

Have been using STM32CubeIDE with several processors and different Nucleo boards with success

Acquired a Nucleo-U575ZI and when I try to download code I get:

STMicroelectronics ST-LINK GDB server. Version 6.0.0

Starting server with the following options:

Persistent Mode : Disabled

Logging Level : 1

Listen Port Number : 61234

Status Refresh Delay : 15s

Verbose Mode : Disabled

SWD Debug : Enabled

InitWhile : Enabled

Target no device found

Error in initializing ST-LINK device.

Reason: No device found on target.

Checked the obvious

Updated ST-Link

Checked all the jumpers

Tried different machines (that also work well with other boards/processors)

I can erase the device with STM32CubeProgrammer and it appears I can upload to just the first sector with that tool

Corrections - it's not the first sector that can be written to just the first 16bytes

I can do a Full chip erase with the STM32CubeProgrammer:

14:09:16 : MASS ERASE ...

14:09:16 : Mass erase successfully achieved

14:09:16 : UPLOADING ...

14:09:16 : Size : 1024 Bytes

14:09:16 : Address : 0x8000000

14:09:16 : Read progress:

14:09:16 : Data read successfully

14:09:16 : Time elapsed during the read operation is: 00:00:00.006

And the memory shows all 0xff

Created a small executable (tmp.bin) and when attempt to load it with STM32CubeProgrammer:

14:11:14 : Memory Programming ...

14:11:14 : Opening and parsing file: tmp.bin

14:11:14 : File : tmp.bin

14:11:14 : Size : 32445 Bytes

14:11:14 : Address : 0x08000000

14:11:14 : Erasing memory corresponding to segment 0:

14:11:14 : Erasing internal memory sectors [0 3]

14:11:14 : Download in Progress:

14:11:14 : Error: Fail to write buffer in flash

14:11:14 : Error: failed to erase memory

14:11:14 : Error: failed to download Segment[0]

14:11:14 : Error: failed to download the File

When I read the flash only the first 16bytes are written the rest are all 0xff

Following that I can no longer do a Full chip erase with the STM32CubeProgrammer

14:12:39 : MASS ERASE ...

14:12:40 : Error: failed to erase memory

14:12:40 : Error: Mass erase operation failed.Please verify flash protection

until I do a reset and then I can erase again

Brand new board, seeing as we have a serious lack of enthusiasm for support here it looks like we should try and return it

I had the same problem. I had the Nucleo board on a breadboard at the time. After taking the Nucleo board off the breadboard, debugging it was no problem anymore.

Maybe connecting it to a breadboard is short circuiting some pins.... I'm not entirely sure why it was like that.
