Hi Albrecht, Thank you for your response. Sorry I'm new to QNX. It might work for me. Could you explain a little bit
more? Right now I start like this:
# Starting QSPI flash driver
on -R 0xD devf-qspi-xzynq-zcu102
flashctl -p /dev/fs0p0 -o 0xee00000 -l 0x400000 -e -f -v -U
flashctl -p /dev/fs0p1 -U
flashctl -p /dev/fs0p1 -v -m -n /mnt/flash-partition
How can I create a devb-loopback and encrypt it? Thank you!
