 But with this image the STAT LED goes red in 20 seconds

I've tried to copy the image on an SD card and on a USB, using Win32DiskImager and trying the following commands too, formatting them first with diskpart

$ sudo dd if=build/tmp/deploy/images/iot2050/iot2050-image-example-iot2050-debian-iot2050.wic.img of=/dev/sdb bs=4M oflag=sync
