"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?

[Imen.D]

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.

[Ayang.1]

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

[Ayang.1]

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?

[Imen.D]

Hi @Ayang.1​ ,

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

Imen

[Ayang.1]

Hi @Imen DAHMEN​  your STMCubeprogrammer msut first click "Connect" it will read the chip type and merory automactially if connected sucessfully. You can tyr it your programming software if can do "uncheck" function.

[Houda GHABRI]

Hi @Ayang.1​ ,

This error message is "normal" we cannot read Data when read out protection is equal to 1 (0xBB).

So you need just to click OK to the message then go to Option bytes Tab and modify the RDP value.

Can you please test and tell me if it is Ok?
