Hi,

I got a problem while using STEVAL-IDB002V1 eval. kit.

It is not entering into DFU mode if i follow the procedure as per the documentation (because led is not blinking).

Thanks in advance.

Regards ,

Dear Customer,

The STM32L is preprogrammed with a DFU firmware that allows the downloading of a firmware image without the use of a programmer. If an user accidentally erases DFU firmware, he can reprogram it through STLink using the hex image DFU_Bootloader.hex available on DK SW package, firmware folder.

Regards,

GM

Hi Marchese.Graziella,

I tried that by using STlink but it is also not working. I have attached the log window which shows some warning

Hi,

Thank you... Problem Solved

First i tried IAR compiler and ST link debugger for flashing DFU image file (not solved, that was my 2nd post)

After that i tried ST link utility exe (downloader) and ST link debugger to flash DFU image it solved my issue .

i.e now it can enter into DFU mode
