The interface firmware FAILED to reset/halt the target MCU (NUCLEO-F446RE)

[FAger.1]

Hi, I'm new to this, so bare with me :)

I'm following the UM2421 - getting startet guide for the P-NUCLEO-IOM01M1, and everytime I connect the USB to my PC, I get the FAIL.txt where it says: The interface firmware FAILED to reset/halt the target MCU. I believe that, this problem prevents me for connecting to my IO-link device?

I have tried to reinstall the ST-LINK, update the firmware on the NUCLEO-F446RE, rebooting my PC, but everytime i get the FAIL.txt saying the same thing.

I have no idea what to do, so please if someone have a solution for this problem.

The NUCLEO boards come with an integrated debug interface called ST-LINK/V2-1, on newer devices also the ST-LINK/V3. Beside other cool things these ST-LINKs provide a mass storage to the operating system, e.g. under Windows the next free drive letter. While reinstalling the ST-LINK means updating/reinstalling the device driver of the operating system, updating the firmware means the software running on the target (here STM32F446RE) - but it looks like you didn't update the firmware of the built-in ST-LINK/V2-1.

But don't worry, you can do this easily. Depending on your software setup this can be performed using:

• ST-Link Utility (Windows only) --> ST-Link > Firmware Update
• STM32CubeProgrammer (all platforms) --> Firmware Upgrade
• STM32CubeIDE (all platforms) --> Help > ST-Link Upgrade

...then just Open in update mode (usually you shouldn't check the option Change type, except you know, what your are doing).

Hi Peter

Your purposed method doesn't work either :( The same message (FAIL.txt) pop-up again after I have updated the firmware through the ST-Link Utility. And it also seems that the F446RE already have the newest installed firmware?

I Also get this error-message when i try to connect to the device through ST-Link Utility:

 

[Peter BENSCH]

Please don't be confused by firmware versions:

• the ST-Link Upgrade upgrades the firmware in the ST-Link only, i.e. the debug interface, which in your case contains an STM32F103CB
• the target microcontroller, in your case the STM32F446RE, does not require upgrades, as it already is either preprogrammed with an example software, or you are program it using your own software - let it call firmware

On your 2nd image I can see the ST-Link Utility is still set to mode Normal.

Please change the Mode via Target > Settings to Connect under Reset and try to connect again.

Could it be that I accidentally have upgraded the STM32F446RE, and that's why I get the FAIL.txt?

I also changed the settings to connect under reset , but I still can't connect to the board, and the FAIL.txt still pops up.

 

The LD1, turns green, when i connect through the ST-Link utility, but I still receive the Warning-message as seen on the figure. Based on the UM1724, the LD1 tells that: communication finished and successful. But there must be something wrong, since I still recieve the FAIL.txt?

Sorry for the  inconveniences :(

[Peter BENSCH]

Even that sounds strange indeed, maybe it's for a completely different reason and I'm sorry I missed that: the IO-Link stack is provided by our partner TEConcept, the binary of the firmware is only available there, so TEConcept is very likely protecting the firmware to avoid copying and/or modifying which would explain the message "Disable Read Out Protection and retry".

Please have a look into the UM2421, page 12, where you will find some additional information to upgrade firmware, which requires the IO-Link Control Tool from TEConcept.

I tried their suggestion first, (UM2421, page 12), but that did not work either, I am still receiving the FAIL.txt and the communication between my IO-link device (TA2212 from Ifm) and the STEVAL-IOM001V1 does not work.

This cant be a isolated case, surely someone else must have had the same issue?

I am i touch with TEConcept and if I get a solution I will post it here.

Try connecting BOOT0 to VDD to make sure it is not an issue with user firmware on F4 blocking

To program a secondary target you'd need to disconnect jumpering to the internal target.

Try also removing secondary boards if they are interfering with connectivity.

it's an old thread, but since i just encountered the same issue and found a solution that worked in my case, i thought it would be worth sharing:

please check if you have set USB mode to usb_fs. In this case, an external power source is required. If the boards only power source is the usb st-link port, the  "The interface firmware FAILED to reset/halt the target MCU" shows up in my case and st-link connection could not be established. When i set the jumper back to 5V link or added an external power source, the issue was resolved.

Which board/chip ?

[ADiet.2]

STM32F746G-DISCO Discovery kit with STM32F746NG MCU

I also had the same problem. I solved it by changing the Power-related jumper (just below the rest button). Make sure the jumper is at pin 1 and 2 (using U5V), please check page 21 UM1724 User manual for more information.

I found this guy helped me. Basicly you just holding your hand on the reset of your stm  at the same time you connected to pc and open  stm utility. After then u take back your hand chip will be still there.  Erase the chip. Its all about wrong program downlaod. Nothing more. And don't forget to change your program. Try to understand what is wrong.
