I'm using the i.MX 8M nano evk with the SD Card for booting the board. I built the 5.4.70-2.3.1 release image and loaded the sd card image onto a card using the
sudo dd if=<image>.wic of=/dev/sdb bs=1M conv=fsync
command from the IMX_YOCTO_PROJECT_USERS_GUIDE.pdf.
The first time I execute the dd command on a new SD Card, the image boots into Linux just fine. But if I run the command a second time, the boot process results in a u=boot> prompt and I can never get into Linux again.
I've tried to dd if=/dev/null of=/dev/sdb to wipe out the card and start again, but still unsuccessful. Is there a way to recover the card after rewriting the image to the card?
