|
|
$ sudo scp -r <user name>@<host address>:<your workspace>/acrn-kernel/arch/x86/boot/bzImage /mnt/
|
|
$ sudo scp -r <user name>@<host address>:<your workspace>/acrn-kernel/out/lib/modules/* /lib/modules/
|
|
$ conf_file=`sed -n '$ s/default //p' /mnt/loader/loader.conf`.conf
|
|
$ kernel_img=`sed -n 2p /mnt/loader/entries/$conf_file | cut -d'/' -f4`
|
|
$ sed -i "s/$kernel_img/bzImage/g" /mnt/loader/entries/$conf_file
