i.MX 8M Mini EVK linux - can I increase root_fs size or mount unused SD card space after build?

[rwhitehead]

Hello,

I've built the imx-desktop-xwayland distro and booted it from a 64GB SD card. I've spent some time configuring the OS now.

Unfortunately I forgot to add IMAGE_ROOTFS_SIZE to the local.conf file before the build, so it has built the default 8GB image which is not going to be big enough.

Is there any way I can now increase the size?

Failing that, can I mount the rest of the SD card as another disk? 

I don't really want to redo the 9 hour build and then reconfigure the OS again!

Thanks

Hi @rwhitehead 

Is there any way I can now increase the size?

--->No, the rootfs size has been defined in Yocto.

can I mount the rest of the SD card as another disk?
