Hi

I would like to change the partition table and add a new ‘data’ partition. I used the chapter ‘Change the default NAND partition table (build-time)’ as a blueprint and adjusted the following parts:

- MKUBIFS\_ARGS
- mtdparts “40m(data),”
- bootargs “ubi.mtd=…”

After booting linux I can see the partition:

# cat /proc/mtd

…  
mtd6: 02800000 00020000 “data”  
…

The last step is to mount the partition in fstab. But how do I ubiformat/ubiattach/ubimkvol using yocto? Is there a default recipe available? My guess is to write my own multiubi\_mkfs routine but as this looks like a standard problem I’m hesitating…

Thanks  
Mario

you should be able to create an empty ubifs volume on host and flash it via u-boot. it should be enough.
