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?

Get a current version of STM32 Cube Programmer, v2.6.0 is a bit old​

I upgraded to the latest version.

Then I tried to connect with normal mode and I get the message

When I changed to HotPlug mode and pressed the Restet button on the WIO-5E mini, the programmer responded with several messages:

08:53:48 : ST-LINK SN : 38FF6E0630354E3953271743

But, when I depress this button, it responds with messages:

08:55:38 : Error: Unable to get core ID
 08:55:38 : Error: Unable to get core ID
 08:55:38 : Error: Unable to get core ID
 08:55:38 : Warning: Connection to device 0x497 is lost
 08:55:39 : Disconnected from device.

I still can't program my WIO-5E mini device.

I saw this message above:

Debug in Low Power mode is not supported for this device.

So I have a question. Should I switch to 5V VCC? @Community member​

We have already discussed the issue of ST-LINK/V2 and "certified resellers" several times. Please check your ST-LINK/V2 carefully to make sure it is not another counterfeit.

You can find discussions about fakes e.g. here, there or there.

Good luck!

I bought it from a certified reseller, Waveshare. I wrote this above.

[Peter BENSCH]

Well, Waveshare also sells counterfeit ST-LINK/V2, e.g. this or that one - so much for being a Certified Reseller.

The 2nd URL (chinese version with the woman and the yellow background) is remarkably often a clone. So if you want to be sure, you should check the ST-LINK/V2: often trying to update the firmware to the latest version does not show a meaningful serial number, or you open the ST-LINK and look at the STM32F103 in use, as the previously linked threads show.

Good luck!

NO , no , never ! would kill the chip ! only 3v3 is ok.

and now you can load program to flash also; (dont press reset now, it will stop connection ).

now click download symbol and select xx.bin file, you want to flash:

"and now you can load program to flash also; (dont press reset now, it will stop connection )."

The problem is that when I release the reset button, ST-LINK disconnects from the WIO-5E min. I can't connect to WIO-5 min when I only press the button once and depress it. And, of course, I can't download any program to it in both case. That is my problem.

[Tesla DeLorean]

How is this connected? Like before?

VCC 3.3V

GND

SWDIO

SWCLK

NRST

If NRST is connected then "connect under reset" will work without you needing to press a button.

[markpow]

I have only four wires: VCC 3,3V, SWDIO, SWCLK, and GND on ST-LINK/V2. They all are connected as required to the WIO-5E mini. I don't have NRST wire.

>I upgraded the firmware with a stupid trick

No. thats what you should do, to "start in update mode " .

> Previously downloaded code into WIO-5E sill running,

AAA, new info. It was working before ??

so just look, what you set in option bytes. there is something , that disables SWD , i suppose.

or in your program -> using the SWD+SWC pins for something, change their mode;

+ you set in Cube : SWD ?

@AScha.3​ ​ Here is my view:

It looks completely different from your's view.

But I can't understand the relation between the configuration of an application and trying to connect ST-LINK to WIO-5E mini (with STM32WL5JC chip on the board)

[AScha.3]

ok, (pic was from F072 cpu) , on your WL5x cpu the relevant pins can be set to different functions, if you want SWD debug connect, you must set PA13 + PA14 to SWD+SWC function. otherwise they will do, whatever is set to them.

if you just want flash/load program, maybe you should try bootloader mode and flash this way.
