I wirk with the nucleo board stm32l053R8 and want to program it through the st-link utility

When i use the stm32 st-link utility to progam ( lobard connected and detected by the tool) , it detects the board ( flask size and core), but i have always this error

''No elf loader found for this operation''

so whan i want to download the . hex file, it doenst work.

So do you have an idea of the problem, what can be worng ?

Thanks

What address are you building your code at? 0x08000000 ?

Building it at zero probably isn't going to work. Make sure you have current ST-LINK Utilities, and firmware.

I built at adress 0x08000000 , i have got the last version of the st-link utility and driver.

I can upload binary file when i compile with mbed ( the board is recognized).

i still have the problem

The steps :

i launch he st-link utility,  => ok

i do ( traget -> connect) => the board and stm32L053 recognized

and i have already the window with the error 

''No elf loader found for this operation''

Here is a copy of the screen i got

10:29:18 : ST-LINK Firmware version : V2J28M16

10:29:18 : Connected via SWD.

10:29:18 : SWD Frequency = 4,0 MHz.

10:29:18 : Connection mode : Normal.

10:29:18 : Device family :STM32L0xx 64k

10:29:18 : No elf loader found for this operation.

Thanks
