Hello everybody,

i have a strange problem, hope that someone has a great idea what i can do...

We have custom board's with the stm32f7 and f4. Normaly we flash the device via bat (or open ocd(which is working)).

The bat looks like this:

..\st-link\ST-LINK_CLI.exe -c SWD UR -Rst

..\st-link\ST-LINK_CLI.exe -c SWD UR -P firmware.hex..\st-link\ST-LINK_CLI.exe -c SWD UR -P bootloader.hex..\st-link\ST-LINK_CLI.exe -c SWD UR -Rst

pause

Since someday's i get the follow error message while flashing:

The elf loader file is not accessible.

This is the complete output from the console:

ST-LINK SN : 33FF68064D4E353545150843

ST-LINK Firmware version : V2J24S4Connected via SWD.SWD Frequency = 4000K.Target voltage = 3.2 V.Connection mode : Connect Under Reset.Device ID:0x449Device flash Size : 512 KbytesDevice family :STM32F74x/F75x

Loading file...

Flash Programming: File : firmware.hex Address : 0x00200000Memory programming...?????????????????????????????????????????????????? 0%The elf loader file is not accessible.

We have this problem on two PC's and one PC is working.

I already tried:

Flashing via St-Utility -> Working without a problem

Flashing via openocd -> 

Working without a problem

SWD Frequenz to 1800K -> Same problem

Updated St-Utility 

-> Same problem

Firmware Update the St-Link 

-> Same problem

Take a Brandnew ST-Link 

-> Same problem

Updated Win driver 

-> Same problem

Taking the st-link from the pc which is working 

-> Same problem

What can i do or try?

If you know something i would be very happy

Thank you and have a nice day!

Are you sure you are not having spaces in the path name of your ELF file ?

And if so, is the path surrounded by ' - characters ?

Yes i'm hundert percent sure.

But you have give me a idea. 

I copyd the bat and hex file directly to the st link folder. There It's working. So for me it looks like i have a not acessable file or something like this.

Path names in Windows are often not what it seems.

And for certain system paths special restrictions apply, and strange this happen if you try 'normal business' there.

I would switch the batch echo output on, to see the actual path. Perhaps another invalid character.
