How to program WIO-5E mini (Seeed) using ST-LINK/V2 mini (Vaweshare)

[markpow]

I bought ST-LINK/V2 from a certified reseller, and I have WIO-5E mini with STM32WL5JC from [Seeed.com](https://Seeed.com) on the board. This WIO-5E was already programmed by another ST-LINK/V2. I connected WIO-5E to ST-LINK as required. I want to reprogam WIO-5MINI using this programator. But STM32Programmer answered:

What should I do so STM32Programmer will see STM32WL5CJ from the WIO-5E mini board?

so - what you did ? already killed the firmware ?

Yes, the firmware was cleared, and the protecion level was set up to AA. After that, I might upload code (.hex) to WIO-5 min. In the beginning, I would ask the chip using AT commands. After clearing the firmware, it's obvious that I can't ask with AT command. But I might program this chip. I saw that WIO-5 contacts to Chirpstack gateway.

so...i hope, you know, what you are doing. :)

• in CubeProgrammer, set software reset
• connect (under reset - press reset button, then 'connect') . works ? can load program ?
• or try bootloader: press reset, press boot, release reset , then release boot. now should connect in bootloader, select in Cubeprogrammer not STlink, but rs232 or usb - whatever your chip can do (read manual!) and for rs232 need ie rs232 - ttl adapter to connect to rs232 rx-tx on chip pins.

maybe, you have to set option bytes , or set swd on start of your program, to have it always available (to connect by STlink -> SWD ) and debug or load program.

For everyone who will search for a solution.

Steps to attach WIO-5E mini to ST-LINK.

Wire connections:

ST-LINK

1 => VCC

7 => SWDIO

9 => SWCLK

15 => NRST

20 => GND

 

WIO-5E pins mini should be connected to pins with the same names as for ST-LINK.

Open the STM32Programmer, press the button Connect (look at settings before)

You should see the following response (without another serial number for the ST-LINK).

So next, run STM32CubeIDE, go to option Run => Debug configuration, switch to de Debugger tab.

Do the following steps:

1. Click on the Shared ST-LINK checkbox.
2. Press the ST-LINK SN checkbox and press the Scan button. The textbox should be fulfilled with the serial number of the ST-LINK programmer.
3. Press on the Show command line button. Copy that command into the command prompt and run it.
4. Press on the Connect to remote GDB server radio button
5. Press the Apply button.
6. Press the Debug button.

And finally:

 

The end of the story.

PS. Next time, when you will try to debug, don't forget about point 3 from the above list.
