"Error: -- Reserved --" message when trying FUS upgrade via SWD

Hi everyone,

Up until now I've been doing FUS upgrades and BLE stack flashing on my WB55 Nucleo through the USB bootloader interface, but given that my final PCB won't have a USB port on it (space restrictions), I've had to start learning how to flash through the SWD instead. Following the instructions in the release notes for the wireless copro binaries, I can run -fwdelete just fine, and I can also successfully upload the BLE stack and run my application after that. My only concern is that when I try doing an FUS upgrade with:

STM32_Programmer_CLI.exe -c port=swd mode=UR -ob nSWboot0=0 nboot1=1 nboot0=1 -fwupgrade stm32wb5x_FUS_fw_1_0_2.bin 0x080EC000 firstinstall=0

I get the following output:

I don't know if I should be concerned about that "Error: -- Reserved --" message or not. The FUS itself seems to be active given that -fwdelete and BLE stack flashing works. Also, the FUS on the board is up-to-date from when I was still flashing through the USB bootloader interface. So is this just CubeProgrammer's way of saying there is nothing new to update, or a deeper problem that'll prevent me from updating the FUS on my actual PCB?

Could you try with the most recent FUS version 1.1.0 available in the CubeWB FW package V1.5.0 available on st.com since last week? the V1.0.2 is old now.

Could you also check that you are using Cube Programmer version 2.3.0? This would ensure you are using the latest FUS_operator version.

What might have happened with this stm32wb5x_FUS_fw_1_0_2.bin is due to the fact that this FUS version was already the one available on your board.

But there are also errors when trying to reconnect after the FUS_operator download.

What is strange is the expected size of the FUS_operator (only 3 sectors)? With the Cube programmer version I have, 4 sectors are erased (not 3 as I can see in you log file).

I recently updated CubeProgrammer to 2.4.0 and downloaded CubeWB 1.5.0, so I think everything should be up to date.

This is the output I get when trying to upgrade the FUS to 1.1.0. It's similar to when I tried to "upgrade" to 1.0.2, which I again suspect because the board was already running 1.1.0 to begin with.

I may have answered my own question; I'm leaning heavily towards this being a false alarm that Programmer throws when the FUS is already up to date. I managed to get another Nucleo from a friend that was running the outdated FUS from CubeWB 1.4.0, and I tried to upgrade the FUS to 1.0.2 like before, followed by upgrading to 1.1.0 from the latest CubeWB. This time, the 1.0.2 failed with a FUS_STATE_IMG_NOT_AUTHENTIC, which I remember previous posts saying was an indication that the FUS was already at this version. Following this, the 1.1.0 upgrade went through successfully.

Furthermore, after the 1.1.0 upgrade, repeating these commands after this yields the same behaviour as before with Error: -- Reserved --.

So I guess it's nothing to worry about?
