Hello @NHarr.2​,

Which board are you using? or using your own custom board?

Do you use the CubeProgrammer tool in GUI mode or via the command line interface (CLI mode)?

which version of CubeProgrammer ?

[NHarr.2]

it also show current value as E7.

Try connecting under reset, checking NRST.

Did you try BOOT0 strapped to VDD?

check this ST video: STM32 Security tips - 3 RDP without POR

STM32F405RGT6 running on a vesc board. i am using the gui cube programmer v2.12

Does STM32 Cube Programmer correctly identify the chip? Perhaps show the whole window to provide some context.

You're using an ST-LINK/V2 or V3? Authentic?

Direct USB connection, or via a hub or docking station?

Your board connects/functions otherwise?

What's voltage measured on VCAP pins?

What version of Windows?

If you're going to nudge a thread, add more detail / context.

Hi All,

I am also facing Option Bytes programming problem

In my case STM32G031F8 with RESET pin (Pin6) needs to be programmed as I/O .

Which the parameter is option bytes needs to be NRST_MODE= 2 (Default state 3).

I am not able to set this level via "STM32CubeProgrammer API v2.12.0 | Windows-64Bits "

Sequentally gives and messages "nSWAP_BYE does not exist", "DUAL_BANK does not exist" warnings and "DUAL_BANK is not programmable". I can able to program it via ST-LINK Utilty. As far as I remember that I was able to program with Cube Programmer before with old versions.

If it possible to fix that error?

Also the revision of v2.12.0 gives many pop-up "OK" messages while programming. So, everytime I need to click "OK" 2-3 times.

Regards

Murat
