Make bootload on WIO-5 mini (STM32WLE5JC) [SOLVED]

[markpow]

I have a WIO-5 mini from Seeed. I bought STM-LINK V2 to program it. But I can't attach it to STM32 Cube Programmer; I read this page Wio-E5 mini - Seeed Wiki (seeedstudio.com), but I found it completely unusable. I tried to connect STM8 wires to that chip, but the cables on the photo are entirely different from those in my ST-LINK device. They have different colors, and the authors of this page don't explain which pin should be attached to WIO-5 pins. I tried to do it in many ways, but STM32 Cube Programmer doesn't;t react to Connect button (without success or fail message)

So I have a question, how to program a WIO-5 device using ST-LINK?

Use the 20-pin Header of the ST-LINK/V2

Get some dupont wires of your own

You want the SWDIO, SWCLK and GROUND at a minimum, on the official ST-LINK/V2 you need to power the buffers, so VCC also. You could also connect NRST

Pin 1 VCC

Pin 7 SWDIO

Pin 9 SWCLK

Pin 15 NRST

Pin 20 GROUND

I attached wires as you mentioned.

I pressed on Rest button on the WIO-5 Mini. Having this button pressed, I clicked on Connect button (having ST-LINK selected from the list).

Nothing changed. I ST-LNIK didn't recognize WIO-5. What am I missing?

The serial number suggests it is a bootleg ST-LINK/V2

The power should only be 3.0 to 3.3V, yours looks to be reporting pushing 5V

Sorry, can't see the WIO-5 side connectivity, not in focus.

Choose Hardware Reset, and connect under reset..

So I will show you a little bit closer.

First view of ST-LINK connections

As you can see:

1. red -VCC
2. blue - SWDIO
3. yellow -SWCLK
4. white -NRST
5. gray - GND.

Next view of connections to WIO-5 Mini board:

 

1. red - 3.3V
2. blue - DIO
3. yellow - CLK
4. white - RST
5. grey - GND.

Having these connections, I press the Reset button on the WIO-5 mini board and hold it. Next, I click on the button Connect on the STM32 Cube Programmer window. It still doesn't recognize my WIO-5 Mini board.

Maybe these pieces of information will be helpful. WIO-5 mini is a brand new one. It was never programmed using STM-LINK or any other bootloader tool.

I expected it to be elementary, as for programming with Arduino IDE. But still have strange problems with the WIO-5 MIni board and ST-LINK.

PS. I can send AT commands to this board using Termite, in my case. It responds properly. So it works and is alive.

Maybe it will be helpful. I read the documentation of STM-LINK and found that I can check if my installation is proper. I run such a command:

STM32_Programmer_CLI -l usb

I got an unexpected result:

But I see ST-LINK in the device manager

I see it under the option Universal Serial Bus Devices and DM says that it works properly.

I checked Windows Update and USB 3.0 drivers. They are up to date.

What is wrong?

STM32_Programmer_CLI.exe -c port=swd

Something is wrong. ST-LINK doesn't see the WIO-5 mini-board.

I link the WIO-5 board to the STM32 by wires as is in the above pictures. I don't see any mistakes in the connections.

I applied a note from Drew from this thread How to fix STM32 Stuck with error ST-LINK error (DEV_TARGET_NOT_HALTED) - Electrical Engineering Stack Exchange and I got an answer:

And it is exactly my STM chip discovered.

But I still have this:
