Hi, am using the STM32WB55 Nucleo board. My problem is, currently I

seem not to have a CPU2 wireless stack loaded and I fail to load file

stm32wb5x_BLE_Stack_full_fw.bin loaded into the Flash. I am using the

STM32CubeProgrammer V2.12.0. When selecting on the Firmware Upgrade

Service Button and clicking on "Read FUS infos", I get:

FUS State: FUS_IDLE

FUS Status: FUS_NO_ERROR

FUS Version: v0.0.0.0

FUS Operator: v3.1.0

When I click on "Start Wireless Stack", this happens:

So it seems, there is no Wireless Stack present. And if I try to load

it, this also fails: I want to use stm32wb5x_BLE_Stack_full_fw.bin

(V1.15). From the release note, I learn that the correct start address

is 0x080CE000. I have the

"First install" checkbox deselected, and the "Verify download"

selected. The Start Address field is set to 0x080CE000. On clicking

"Firmware Upgrade", I get this log:

I have found some similar questions:

Issue: Attempting to flash firmware onto coprocessor on STM32WB55RGV6

results in Error: FUS_STATE_ERR_UNKNOWN

[STM32WB55 Nucleo] Unable to update FUS or the wireless stack

(FUS_STATE_ERR_UNKNOWN)

but both threads do not seem to have a solution.

I also read the AN5185 as well as the STM32WB_FUS wiki I am not allowed to post a link here, so I will split it:

"stm32mcu/wiki/Connectivity:STM32WB_FUS"

on

wiki.st.com/

but to no avail.

I tried to identify the FUS version. IPCCDBA option byte is 0, but the whole

memory starting at 02x0030000 contains only 0x000000, so I don't find

the Device info table.

The SBRV option bytes contain 0x3d800, so this seems to indicate I

have FUS V0.5.3 loaded.

These seem to be the relevant option bytes on my board:

RDP: 0xAA (nor read protection)

nBOOT0: 1

nBOOT1: 1

ESE: unchecked

SFSA: 0xd4

FSD, DDS, C2OPT, NBRSD: checked

SNBRSA: 0x13

BRSD: checked

SBRSA: 0x0a

SBRV: 0x3d800

Any help would by nice!

Regards

Dirk

On left side release html info is step by step howto update. Primary first need update FUS.

The problem is, that step 4 of that instruction does not work, i.e. I have no reliable information about the current FUS version (0.0.0.0 is not mentioned as possible value). I only assume it is 0.5.3 from the SBRV value, but I am not sure. And I don't want to brick my board.

Use GUI Programmer not cli

Just the same problem, see above: "FUS Version: v0.0.0.0"

And reading from 0x2003000 on gives ony 0x000000 for the whole range.

If you dont sucess maybe this help Unable to start FUS

zabelAuthor

Had no success, could not update the FUS (ended up with "FUS_STATE_ERR_UNKNOWN). But your reference looks promising, at least the symptoms look very similar to the observed ones. Once again thank you for your help!

I have same issue, but with STM32WB15. Today I was updating it to 1.16 and got the same symptoms, option bytes are slightly different:

SBRV: 0x8400

SFSA: 0x31

When I click on read FUS infos, sometimes it shows FUS Version v23.ffffffa8.7d.ffffffef, but 99% of the time it shows 0.0.0.0. Start FUS always gives an error.

Try slow down stlink speed from 4M to 400kHz or less

zabelAuthor

Still no success, latest try was reducing the stlink speed to 100kHz.

Refer this wiki for such issues: STM32WB Firmware Upgrade Service - stm32mcu (stmicroelectronics.cn)

See section FAQ.

Most of the time, safeboot is triggered due to corruption in option bytes or voltage fluctuations. See specifically

Accidentally, I got SFSA = 0x00 and SBRV= 0x3FC00 what's happened?

This is due to option byte corruption, or to supply voltage or level stability. This configuration of the SFSA/SBRV option bytes means that the STM32WB hardware forces the boot to Safeboot whatever the firmware being run. To activate Safeboot and perform a factory reset the user must activate the Cortex-M0+ by writing the value 0x00008000 to address 0x5800040C using the SWD interface.
If a FUS version lower than V1.1.0 is running, then no recovery is possible at this point.
