however lsusb shows:

Code: [Select]

Bus 001 Device 013: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

which seems to indicate dfu mode is working on the preenfm side. the other preenfm updates the firmware without a problem on the exact same linux installation, same usb port and cable...

any hints on this?

i solved it by removing the usb-stick (pain in the a**) because you have to open the case. i then uploaded the new firmware directly to the stick (usb-stick mode in bootloader was also not working)

after reinserting the stick i got a "bootloader ok, but no firmware installed" screen and i was able to boot to bootloader and flash the new firmware. now i am again able to flash via dfu mode...

this seems odd and weird.
