How do you install WB RF stack?

[DOCon.1]

Hi. I've read several bits of info on the RF stack installation, but can't figure it out. Here's a previous thread on the topic:https://community.st.com/s/question/0D53W00000DKLKkSAP/how-do-i-flashburn-the-ble-stack-coprocessor-binary-for-my-stm32wb55ce-custom-board

I have STM32Cube programmer open, with the `Erasing and Progamming` tab selected. I have 3 binaries, downloaded from here: https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x. `FUS_fw.bin`, `FUS_fw_for_fus_0_5_3.bin`, and `BLE_Stack_full_fw.bin`. Presumably I install FUS for 0_5_3, then FUS, then BLE stack. How do I know what Start Address to use in Cube Programmer? The link above suggests it's in the Release Notes doc, but I don't see it there. There's also a reference to Table 5 in ANSI5185, but I don't see it there; that document is a changelog.

Question #1: Is my procedure correct, of flashing those 3 binaries in sequence from `Erasing and Progamming` in STM32Cube Programmer?

Question #2: Where do I find the Start Address?

Question #3: When I go to the `Memory and File edition` in CubeProgammer, and enter `0x20030030` in the `Address` field at the top left to check FUS version, it shows 0s. According to ANSI5185's FAQ, this may mean CPU2 is off. Isn't it by nature off when I load up Cube Programmer vice a program where I set C2BOOT in PWR_CR4? Related: By using Full Chip Erase in CubeProgammer (Which is normally a safe operation on other STM32s), could I have bricked the RF CPU? Or does that only erase normal program memory?

Alternatively: Is there a self-contained guide on how to set up CPU2? The guides I've mentioned and some others all contain references to dead-ends, or leave out key information.

Hi @DOCon.1​ ,

In STM32CubeWB Github repository, the same question is asked in the file how_to_program_wireless_stacks.txt. And the provided answer is:

To program a wireless stack inside STM32WBxx devices, you need to refer to the following release notes: - For STM32WB5x devices:

• Projects\STM32WB_Copro_Wireless_Binaries\STM32WB5x\Release_Notes.html. - For STM32WB3x devices:
• Projects\STM32WB_Copro_Wireless_Binaries\STM32WB3x\Release_Notes.html.- For STM32WB1x devices:
• Projects\STM32WB_Copro_Wireless_Binaries\STM32WB1x\Release_Notes.html.

The Start Address is provided in these Release_Notes as well.

Hi. Thank you for the information. That's the changelog I referred to. I don't see any instructions or addresses.

What part of that document should I look in?

To make sure we're talking about the same thing:

Nvm, found it! Turns out I did something wrong when saving that HTML file to Desktop (?) and the tables got mangled. Thank you.

edit: I was looking at the main repo `Release Notes` instead of the one you linked in the folder.
