STEVAL-ISB044V1 cannot communicate with ST-Link V2

Dilemma
Associate II

Hi all,

I'm using theᅠSTEVAL-ISB044V1 evaluation board for the wireless charging test. The evaluation board is based on STWBC-EP and can be programmed with ST-LINK V2. STM8AF6166 is the core of it, so I post here. I tried to program the board, and there's always a connection problem. It looks like the following:

I've tried a USB 2.0 port and USB 3.0port, and I can make sure I've installed all the required tools. Would you please tell me why there's a communicate error? And how to force the NRST Reset pin to"low"?

Besides, since it's the first time I use an ST product, I do not quite understand what's the meaning of programming. What can I achieve by programming the STWBC-EP? What's the meaning of programming? Do you have a tutorial for programming on ST evaluation boards? Because there's no related description on the User Mannel for STEVAL-ISB044V1. And would you please tell me how to get the power requested by the receiver from the evaluation board? Much appreciated.

Besides, is there any commercial products for wireless charging using STWBC-EP?

I'm new to ST products, and if there's anything inappropriate please let me know. Thanks you all!

Somehow the figure didn't appear. It's looked like this

Are you sure you connected the SWIM connector correctly? On that board the connector is not keyed, so it is possible to connect it the wrong way. The error message looks as if the connection between the host and the ST-LINK V2 is ok, but the connection between the board and the ST-LINK V2 is not.

The meaning of programming is to put a custom program on the device, to customize its functionality to your needs. Unfortunately, I do not have a STEVAL-ISB044V1 yet, but for lots of other STM8 boards I wrote short tutorials on getting started (i.e. writing a small sample program onto the device using a version of ST-LINK):

Thanks for your reply. But I do not quite understand what does the sentence "the connecter is not keyed" mean. On the user manual of the board, the connection looks like this:0690X000009k8BAQAY.png

and here's my connection:0690X000009k8BtQAI.jpgAlthough there's a communicate error, the light on the ST-LINK V2 is green. If I change the connection way, it will turn to orange or red.

Would you please tell me the correct way to connect the ST-LINK V2? Thanks.

The connection on the picture looks ok, so its probably some other issue.

Have you tried with alternative software (e.g. if you are using STVD, you might try stm8flash), so we can rule out a problem with your software installation?

Have you tried using a different ST-Link (e.g. one of those cheap Chinese clones), so we can rule out a problem with your ST-Link?
