CubeProgrammer 2.11.0 Bootloader revision reading bug

[Kraal]

Hello,

I have updated CubeProgrammer to its latest revision (2.11.0) and it finally displays the bootloader version in the target information box (with a Nucleo-G070RB).

However it keeps reading the bootloader revision every 1 second, as shown by the log below:

Is it on purpose ?

Also the bootloader revision does not appear with a Nucleo-L053R8. Both boards ST-link have been updated to the latest revision V2J39M27.

Why can't we have the bootloader displayed for all devices ?

Update on this matter:

I tried with a Nucleo-G0B1RE, also with its latest ST-link update.

The bootloader version is not displayed either, despite being a new board release (MB1360-G0B1RE-C02).

I hope this will improve in the next release...

The constant probing is also annoying. Especially when testing/logging work on external loaders.

Surely presence detection would be better done, more transparently, on the ST-LINK side of things, ie in the driver, or in it's firmware. Perhaps sensing if SWDIO, SWCLK, or NRST tri-state at a basic level so it's less intrusive?

Hi @Kraal​ ,

You are right , no need to read BL version continually when connecting using STLink.

I submit an internal ticket to fix this behavior.

Also, for L0 family reading BL is not yet supported by CubeProgrammer, ticket inserted to add it in future release.

Internal ticket number: 133017  (PS: This is an internal tracking number and is not accessible or usable by customers).

Hi @Houda GHABRI​ ,

Thank you for the follow-up.

Regarding the L0 ticket, be aware that for L010K4 and L011K4 the address of BL revision in system memory does not match AN2606.

Reading 1 byte at 0x1FF00FFE return 0xC0 for L053 (as expected), but returns 0x00 for L011. If the address is changed to 0x1FF00FFF, then it returns 0xC2 for L011 (better, but I was expecting C3 according to AN2606).

Interestingly enough, reading 0x1FF00FFD return 0x31 (as in USART V3.1) and reading 0x1FF00FFB returns 0x11 (as in SPI V1.1) on the L011K4.

Best regards,

Kraal

Hi @Kraal​ ,

Thanks for all your interesting feedbacks, I will raise it to BootLoader team.
