How to format the TF/mmc?

[buershan]

Hi, I am trying to enlarge the "overlay" with a partition of the TF card, but failed to format it into ext4.

the TF card, 128G with 2 partitions, is recognized in the "block info",
but mkfs.ext4 does not work.

Any suggestions are appreciated!!

/dev/mtdblock6: MOUNT="/overlay" TYPE="jffs2"
/dev/mmcblk0p1: UUID="D615-CCD0" LABEL="U_8G" TYPE="exfat"
/dev/mmcblk0p2: UUID="AABD-6737" LABEL="U_111G" TYPE="exfat"

The file dev/mmcblk0p1 does not exist and no size was specified.

I'd start by installing an official build of OpenWrt. You appear to be using the GL-Inet firmware which probably operates differently. So, with OpenWrt installed, you can follow this guide and you'll be able to do what you want:

Using storage devices

(USB and SD cards are essentially the same from the perspective of the operating system).

Or, alternatively, you could ask these questions on the GL-Inet support pages if you want to continue using the firmware they provided.

@buershan

mkfs.ext4 dev/mmcblk0p1

mkfs.ext4 /dev/mmcblk0p1

See the difference.

Yes, that works
My fault. Thank you very much!

Thanks a lot!

I missed the slash beore "dev/". Now the format is performed.
