Can't write option bytes with stm32cubeprogrammer

[VPurb.1]

Is there any option to write option bytes to control the boot option for STM32G070 from uart after the first upload or any solution to change the option bytes from stm32cubeprogrammer?

I can't change the boot config from option bytes using the stm32cubeprogrammer, I've used multiple virgin mcu, STM32G031, STM32L071, STM32G070, but none of it can change the option bytes.

Possibly the closest problem is like in troubleshooting section of https://www.beningo.com/configuring-the-stm32-option-bytes-using-segger-j-flash/

Hi,

I have Nucleo-32 with a STM32G031. I just did a quick test and I confirm that I can change option bytes with STM32cubeprogrammer v2.8.0 connected via UART.

The console in your screen shot shows lots of general comms issues. Are programming issues isolated to option bytes?

I've included a screen shot of what I see for the same operation.

Cheers.

Hey @RetroInTheShade, 

 

do you know how to open the settings for nBoot0 and nBoot1. I only have these settings under "User Configuration":

 

Thank you!
