ST-LINK V2 Update error Unexpected flash size

[Andreas_Engineer]

Used this ST-Link V2 with W10 some years ago. Now on Linux I want to use it with openocd and got error:

ST-Link version does not support DAP direct transport

Most likely the cable adapter needs update.

But the STLinkUpgrade.jar reported  Unexpected flash size after opening the cable in update mode.

What can I do to use the cable?

1, Which st-link v2 - the "usb-stick" ?

2. Version of st-link firmware on it ?

3. Use with ..IDE or CubeProgrammer (on Linux, i use it also) ?

4. Check with CubeProgrammer - connect - what it telling ?

There are low cost CMSIS-DAP dongles if you need such things.

There is also a tool to convert ST-LINK/V2-1 to Segger J-LINK OB

What "ST-Link V2"? Did you mean to add a photo or link?

Beware that any so-called "ST-Link V2" looking like this:

is not a genuine ST product - so you get what you pay for!

I am getting the same error on a genuine ST Link v2. My StLink looks like https://uk.farnell.com/stmicroelectronics/st-link-v2/icd-programmer-for-stm8-stm32/dp/1892523

I have exact the same white st-link v2. The cube programmer v2.16.0 with stlinkupgrade v3.13.4 successfully upgraded my debugger to V2J43S7. This firmware version is at least works with cubeIDE v1.15 although it still triggers the upgrade prompt and the unexpected flash error. However, my NUCLEO F446 has no problem at all. It can be perfectly upgraded inside the cubeIDE v1.15.

It seems like the cubeIDE v1.15 is a major and painful upgrade and it already cost me hours to fix a lot of things. It is obviously not a smooth upgrade. Be careful about the ioc migration and make backup. I have experienced a failure after the IDE upgrade. Without changing any code and just migrate the ioc, recompile and flash, totally not working. However, when I reloaded my backup and migrated again, everything worked.

Considering almost everything are free, I would not complain about ST or cubeIDE team.

I have been using CubeIde 1.10.0. But as part of project migration had to upgrade to 1.15.0. But the ide wont download the application image till I upgrade the firmware of StLink. Unfortunately, stuck with the STLink firmware upgrade!

again:

4. Check with CubeProgrammer - connect - what it telling ?

Please see below.

I tried to upgrade the firmware using CubeProgrammer too. Unfortunately it reports STLinkUpgrade.jar not found.

Encountered Same Issue

Same here.

the same issue "unexpected flash size for st-link micro"

[volmyr]

I was able to upgrade, I've downloaded https://www.st.com/en/development-tools/stsw-link007.html a previous version - 3.13.4.

[imahgin]

As I stated, STMCubeProgrammer version -2.16.0- includes the Firmware Upgrade utility and the STLinkUpgrade launched is version 3.13.4 which works as expected.

I am seeing this issue also. Using CubeProgrammer still causes the popup too.

Same problem with STM32CubeIDE 1.15.0, launching STLinkUprade 3.14.5, while I play with an STM32F429I_DISCO board. Will try the stand-alone programmer.
