STM32CubeProgrammer v2.21.0

Hello @Phumphathai and welcome to the community;

 

Could you please give more detail about the issue, which STM32 are you using? Are you using STM32 board?

Could you please check the STM32CubeProgrammer version? The latest STM32CubeProgrammer version is 2.19.0.

 

Could you please try to update your toolchain and to use STM32CubeProgrammer 2.19.0 version 

Please let me know if the issue is solved or not?

Thank you.

Hello

 

I use STM32L476VG with custom board. But without any board connect to USB to UART this still happen.

I use STM32CubeProgrammer v2.21.0 I think this is latest version

 

As @Pavel A. show. Delay Pulse text box is read only and cannot fill any value

Thank you

So, presumably, this must be coming from some configuration that you should supply?

And that value is missing or invalid.

The first message just tells you that it's using a default instead.

 

The rest of the video shows that there is no response from your target.

Of course it would - with no board connected, there will certainly be no reply!

So please give details - schematic?

Are you using the System Bootloader, or a custom bootloader?

Hello

 

I update to this version 2 day ago. Now I uninstall and reinstall with v2.19.0

I haven't found any new updates.

Maybe I update to Test on Production Version.

 

Thank you.
