Writing UBI image directly to flash from barebox

Writing UBI image directly to flash from barebox

[Guillermo Rodriguez Garcia]

Hi all,

I need to write an UBI image (generated by ubinize) directly to flash
from barebox. Does barebox provide any equivalent to U-boot's
write.trimffs command for this?

(I know that it is possible to write a ubifs image to flash using the
procedure described in the documentation [1]. What I am looking for is
a way to work with the UBI image directly)

 [1]: http://barebox.org/doc/latest/user/ubi.html

Thank you,

Guillermo Rodriguez Garcia

If you have a mounted ubi volume, you can use "cp" for this.

ubiformat /dev/<your-partition> -y -f /mnt/tftp/<your-ubi-image>

You can use ubiformat MTDEVICE -f FILE to format and flash the ubi image.

I did not realize that ubiformat could also flash an image. This works perfect.

This may fail if the used tftp sever don't support the reporting of the file
size. The file size then defaults to -1 and ubiformat complains.

ls -l /mnt/tftp/barebox.bin
-rwxrwxrwx 18446744073709551615 /mnt/tftp/barebox.bin
