Error: Uploading Option bytes bank: 0 failed

[Anvit]

Hi all,

I'm trying to flash a fresh STM32G0x1 MCU (Device ID: 0x466, Revision ID: Rev 1.1) using ST-LINK V2 (FW: V2J48S7) in Hot Plug connect mode with Hardware reset mode, SWD frequency 100 KHz, target voltage reading 3.26V.

ST-LINK connects and correctly reads the Device ID and Revision ID, but then fails with:

Error: Unable to get core ID
Error: Unable to get core ID
UPLOADING OPTION BYTES DATA...
Bank: 0x00
Address: 0x40022020
Size: 108 Bytes
Error: Uploading Option bytes bank: 0 failed
Error: Initializing the Option Bytes failed
Disconnected from device. 

Things I've tried: 1. SWD wiring (SWDIO, SWCLK, GND, NRST, 3.3V) checked 

2. Target voltage reads 3.26V, stable

3. Tried Hot Plug + Hardware reset mode

Any guidance on the issue would be appreciated.

Thanks!

Hi ​@Anvit ,

Is the issue faced using STM32CubeProgrammer tool?
