Get Version bootloader command ignored on STM32WB09KE

Question

Hello,

I'm encountering the same issue, and i started debugging the embedded bootloader protocol manually.
Or i'm starting getting crazy, but what specified in AN3155 is not respecting what i'm having on the serial port.
I'm using NUCLEO-WB09KE(MB2032B) mounted on MB1801D.

When moving JP1[MB2032B] to BOOT mode, SWD is not available.I'm only be able to get on bootloader mode (not with CubeProg) but as below.

Problem 1 - GetVersionComand (documentation mismatch)

I sucessfully entered in BL (Ack = 0x79), however GetVersion command is totally ignored.
I then tested with another command to see if the communication with embedded BL works.
Something worked but not as expected.

Command 0x02+0xFD should reply with ACK(0x79) + N=NumberOfByte + PID. I did not see 0x79 as ACK nor the number of bytes i should get: i just got 0xD0 and 0x94.
I can't find what is the DEV_ID of STM32WB09KEx, so i can't verify if what'i'm having is really the DEV_ID or something else. Anyway the ACK is still missing.

What's happening there? I get into this because seems the SWD port is disabled due to low-power firmware pre-loaded on the board, so i tried to erase the firmware by accessing the rommed BL. As i was not able to get trough STM32PROG i decided to go "manual way".

Unfortunately after a mass erase i can't access anyway.
As i found mismatch command & replies referred to Uart BL specs, i have doubt i really erased the flash.

Anyone have some direction to point me out?

Thanks

Davide

Hello @Davide Dalfra

I've tested using the STM32CubeProgrammer V2.19.0 and the NUCLEO-WB09KE. I've set the JP1 of the MB2032 to bootloader mode, connected the board throw the STM32CubeProgrammer, set the connection parameters as follow (with no parity):

Finally, click on connect and on the HW reset button of the board. Everything works fine for me:

I think the problem on your side is to use the even parity.

Best Regards.

Ahh, it's right there in AN2606. Had no idea some chip bootloaders used no parity instead of even.

Looks like this is limited to STM32WB0x products, all others use even parity.

@STTwo-32 Thanks for chasing that down.
