Upload fails with STLink2 firmware >= 2.28.18

[FlYnN91]

Hi,

I have found that the qstlink2 (v1.2.3) fails to upload binaries if the STLink2-1 version is 2.28.16. I've noticed that there is a closed ticket already and I did use the ppa to install the 1.2.3 but I believe the issue is still there. qstlink2 works fine (with the same binary file) if STLink2-1 version is 2.23.9.
Also the STM32-Utility uploads the binary file with no problem if the STLink2-1 version is 2.28.16.

I was able to mitigate the issue by downgrading STLink2-1 to 2.23.9.

For future sake, I've attached my binary (blinky) for STM32F429ZI-Nucleo.

I'll run some tests, they probably changed the protocol somehow.

I come to say the same, for version 2.28.18.
An I made used the same 'solution' but with the version 2.27.15, and I saved a copy of this firmware on my github: https://github.com/jano2358/STM32Workout

Hi,
After flashing an stm32f401-nucleo and stm32f469-disco (resp STLinkv2 and STLink v2-1) with qstlink2 (1.30) the mbed virtual drive functionality appears to be broken, in fact when a file is dragged to the drive, it is not flashed to the board.

The only way I found to restore arm mbed functionality is to flash a binary of choice with the stm32 utility for windows, that while flashing reports a read-protection activated.

1.3.0 is not released yet.
Retry with 1.2.3

I moved 1.3.x code to the dev branch since people were assuming it's stable.

Was able to test 2.28.18, seems like the main loader loop does no run.

I can confirm that version 1.2.3 works with both stm32f401-nucleo(2.27.15) and stm32f469-disco(2.27.15). Thanks for moving the unstable code to a new branch, this way the AUR package in Arch Linux installs a working version.
Also I found that STLINK firmware upgrade inside stm32 Utility says 2.27.15 is the latest version, while the standalone firmware update written in java says that 2.28.x is the latest.

Still working on it, they might have deprecated some functions from the V1 API.

@fpoussin I confirmed issue with ST-LINK/V2-1 version 2.28.17 on Nucleo64-F091RC. This issues was also found on the Mastering STM32 Forum (link) and provides a link to a downgraded version 2.24.11 of the the ST-LINK/V2-1 firmware (dropbox link).

Downgrading to ST-LINK/V2-1 2.24.11 on Nucleo64-F091RC fixed issue and allowed .bin uploads to Nucleo64-F091RC. It would be nice for others to share links to more recent versions of ST-LINK/V2-1 firmware that are proven to work, until a fix for the most recent firmware is completed, as ST doesn't provide links to older version of ST-LINK/V2-1 firmware on their website.
