"About the online programming problem on the STM32G030 chip board

Hello, regarding the online burning of STM32G030 on the PCBA board, I would like to know what software is to download for burning? Is it possible to use ST-Link V2? And if the chip program is encrypted and protected, how can I unlock it to burn with ST-Link V2?

Or you can recommend another USB online burning tool that can meet the requirements, thank you.

"

To unlock your board via ST-Link Utility, you can download and install STM32 ST-LINK utility (but it's replaced by STM32CubeProgrammer), then open the app, connect the board and reset the Option Bytes.

Although It's recommended to use STM32CubeProgrammer (STM32CubeProg), a programming tool available in graphical and command-line versions for programming STM32 products. You can "connect under reset" and erase the flash.

I try to connect PCBA board with programer tool STlink-V2, but show can't connect target STM32G030XXX from STM32CubeProgrammer software interface. see below image.But I try STM32F030XXX can connect the target, please let me know what is the problem for STM32G030XXX?

Check if STlink-V3 can meet this requirement?

Have you upgraded the ST-link firmware? go to ST-LINK > firmware update or through this Link STSW-LINK009.

Maybe you should check if the MCU is correctly powered and connected in the right pins !

Yes, I already upgraded the latest FW successfully, see below image.

I can make sure the pin contact is very good and powerd on by 3.3V from STlink-V2 tool. Since this tool has been using STM32F030XXX progrmaming, only changed to new MCU type STM32G030XXX, other no change. programming point is same as STM32F030XXX.

I checked PCBA TopBand supplier, was told if the STM32G030XXX was encrypted protection after programming by them, STLink-V2 tool can't be used, if no encrypted protection STLink-V2 tool can do programming. But you mentioned even encrypted also can be used for unlock and programming, please help, thank you!

[Ayang.1]

I used STLink Utility also happened same error, can't connect the target. I am curious that why STM32F030XXX encrypted protection can connect the target with Stlink-V2 tool, while STM32G3030XXX can't connect the target? What is the difference?

[S.Ma]

G0 is designed for very low pincount packages, compared with F0.

Check boot0, swdio, swdclk and nrst pin configuration and usage in flashed application.

Sorry, I selected under reset mode can connect the device but show "data read" failed, see below image. This was casued by third party chip was encrypted protection?

[Ayang.1]

But I can't find the unlock item from STMCubeprogrammer menu. Do you know how to unlock encrypted protection STM32G030XXX?

[Imen.D]

Hi @Ayang.1​ ,

Is the read protection byte checked? maybe try uncheck it.
