I am using the ST-Link V2 chip to program the update. For this, I downloaded "NET_IAP_DIMMER8_0909.hex" and then tried to update my KC868-D8 device with the STM32F103VCT6 chip. The config in the ST Visual Programmer is set as described in your Youtube video https://www.youtube.com/watch?v=MI2_qAIEt2U 
which means:
CONFIGURATION:
Hardware: ST-LINK
Programming mode: SWD
Device name: STM32F103x8
Port: USB

The version of the ST Visual Programmer is 3.3.2 and it seems not to support the new dongle.

Because the ST Visual Programmer gives me the error below:

Code:

> Programming  OPTION BYTE area...
Error : Wrong device selected ! Check the configuration or the device !
Error : < OPTION BYTE programming failed.

So I downloaded the newest version of the  STM32 Programmer (STM32CubeProgrammer software for all STM32) https://www.st.com/en/development-tools/...s-software
The ST-Link configuration is set to:

In case the image does not work:
Port: SWD
Frequency (kHz): 4000
Mode: Normal
Access port: 0
Reset mode: Software reset
Speed: Reliable
Shared: Disabled

Unfortunately, the new programmer is not able t am not able to connect to the chip. The programmer is supported according to the vendor. See https://www.st.com/en/microcontrollers-m...l#overview
Does anyone know how I could perform the update?

you can download this ST-link software that we have used in our video tour:

this is what I tried and I am getting the error:

Code:

Hardware configuration set to <ST-LINK on USB with STM32F103x8 plugged in and SWD protocol>.
Blank check before programming (when available) is OFF
Verify after programming is ON.
Clear memory before loading a file is ON.
Erase device memory before programming (when available) is ON.
Display a popup window when an error occurs is ON.
Log activity is OFF
> Loading file C:\usr\Local_Work\NET_IAP_DIMMER8_0909.hex in PROGRAM MEMORY area  ...
< File successfully loaded. File Checksum 0x1909E8
> Reading  OPTION BYTE area...
Error : Wrong device selected ! Check the configuration or the device !
Error : < OPTION BYTE reading failed.

any other suggestions?

take a photo of your PCB, i want to see your CPU chip model. it showed: "Wrong device selected ".

It is this one:

you can download this ST-link software that we have used in our video tour:
https://www.kincony.com/download/sttoolset.zip

just use this tool , do as our video, not use the newest tool.

I am using the old tool. See gif:

I guess, my programmer is not compatible. I just ordered another one with the STM32F103C8T6. Let's see if this will work. I will know more by end of March when the dongle arrived.

I had to set the project on hold for a while, but now I am on track again. I have the same dongle as you suggested and also the same software, but I still get the error:

Code:

Hardware configuration set to <ST-LINK on USB with STM32F103x8 plugged in and SWD protocol>.
Blank check before programming (when available) is OFF
Verify after programming is ON.
Clear memory before loading a file is ON.
Erase device memory before programming (when available) is ON.
Display a popup window when an error occurs is ON.
Log activity is OFF

< File successfully loaded. File Checksum 0x1909E8

Error : < OPTION BYTE programming failed.

What am I doing wrong? I hope I did not brick my device.
