Unable to flash STM32G031 (8 pins) with STM32CubeProgrammer & ST-LINK/V2.

[fancyrat]

I've have a custom board with a STM32G031,from the board we have access to the following MCU pins:

• +3V3_BT
• NRSTBT
• SWDIO
• SWCLK_USARTTX

I've connected this 4 pins to a ST-LINK/V2. Like this (left) mcu, (right) st-link.

• +3V3_BT --> VCC
• NRSTBT --> NRST
• SWDIO --> SWDIO
• SWCLK_USARTTX --> SWCLK

The current delivered by PSU goes to almost 0 after trying to flash (around 0.004A from the correct 0.041A). When trying to flash the uC these are the errors/log I get:

Isolating the errors:

Error: Database: There's no active configuration for this device. All the 6 configurations are disabled!
Error: Uploading Option Bytes bank: 0 failed
Error: Initializing the Option Bytes failed

Any ideas on how to solve this?

Thanks!

• which specific STM32G031 is?

Im using stm32g030j6Mx without selecting SW pins and i dont have this issue

•  Which cubeProgr version are you using?

• Did you do the STlink configuration Mode raindance?

Check all posibilities.

Hi Javier,

I'm using STM32G031J6M6 & CubeProgrammer v2.11.0.

I've tried right now other modes. Normal is the one of my post, hotplug has the same errors but the current doesn't change, under reset same errors & also current drop to almost 0, finally power down doesn't react at all "No STM32 target found!" at all times.

This is the ST-LINK configuration I've been using until now:

[MM..1]

Disconect power from your board

connect stlink start in power down mode

click connect

plug power to board

[fancyrat]

Can you please expand on that? If I tri to connect with the board disconnected from power and then I try to "connect" with ST-LINK in power down mode I just get the message "No STM32 target found!"

[MM..1]

Your pin list omit GND i hope connected

and read How to unlock STM32G031J6M6 (STM32G0316-DISCO)?

looks like your ST-LINK may need a firmware update?

I updated the ST-LINK but same problem:

have a different firmware version, why?

Device..ID are same, so what *is* the difference?

Different voltages?

Try lowering the SWD Speed significantly.

still: "Error: Database" makes me nervous.

I'm getting a very similar problem, new board design with STM32G031G4. Any suggestions welcome!

Using STM32CubeProgrammer and STLink, when I connect I get

Error: Database: There's no active configuration for this device. All the 6 configurations are disabled!

and when I program flash I get

File segment @0x08000000 is not 255-bytes aligned. It will be aligned to @0x07FFFFF8

If I connect to a NUCLEO-G031K8 instead, it connects and programs just fine, so I'm assuming these errors are due to a problem on the target board, not anything at the PC end. I also tried STM32CubeIDE, same errors. But if I use the old STM32 ST-Link Utility it can program the target just fine. And STM32CubeProgrammer can then verify the target (compare with file), but still cannot program it. So I guess the STM32Cube* apps are doing things differently to the old stlink utility.

Had a good look at signals with a scope, all looks clean, ground and 3V3 clean. Very simple board, standard SWD connections, I've done lots of similar designs with no problems. Tried running ST-Link at minimum speed, same. What seems strange is it connects, and reads Device ID  : 0x466 Revision ID : Rev Y, so SWD basics are working.

Here's the log from an attempted connect and program

Seems your elf linking script error or buggy stmprogrammer sw. Try flash bin file...

[BenMack99]

I've tried a bin file, same error (File segment @0x08000000 is not 255-bytes aligned. It will be aligned to @0x07FFFFF8). And it works fine if I connect to nucleo board instead of target. And that wouldn't explain the "Error: Database: There's no active configuration for this device" error when I connect.

So I'm thinking something else is going wrong and the PC apps are throwing spurious errors.

[MM..1]

K8 and G4 is different id , but yes maybe other trouble on your board, check vcap power usw...

Somtimes reported errors from prog is long way from real...

STM32G031 programming with ST-Link and CubeIDE failed

[BenMack99]

I've been looking at the Revision ID, STM32Prog reports Rev Y for my board (and Rev 1.1 for NUCLEO). Looking at the reference manual (RM0444 Rev 5) page 1374 Table 254. REV_ID field values, it only lists A (1.0) and Z (1.1). So I'm guessing STM32Prog isn't recognising these Rev Y chips and so is doing silly things. Would explain the "Error: Database: There's no active configuration for this device"

Also, looking at Option Bytes in STM32Prog, it lists lots of duplicates, e.g. BOR_EN, BORF_LEV, BOR_LEV & NRST_MODE each repeated 4 times. Again I guess this could be a symptom of the above.

Why have I got Rev Y chips? And why are they not supported/listed? I guess this a question for ST

[BenMack99]

Just spotted, in Errata ES0487 Rev 5, they added silicon revision Y in May 2022.

Why is it not supported? I'm running latest STM32CubeProgrammer V2.12.0
