Delete partition with "intnvram" command

Hi everybody

Does anybody know how to delete partitions with uboot command “intnvram”? I cannot use “flpart” because it’s not supported in “uboot scripting”.

Thanks in advance,

Try “intnvram help” in uboot console…
you will get all the info

Unfortunately “intnvram help” doesn’t help much…

I tried:

intnvram set partition del select=2

and get the error message:

*** Error: NVE_WRONG_VALUE: (no partition selected)

For creating the partition I use:

intnvram set partition add select=2 name=Kernel start=0x50000 size=0x140000 type=Linux-Kernel

This works perfectly if partition #2 doesn’t exist. If partition #2 exists the command creates partition #3 and adjusts starting address.

In my script I would like to check if partition #2 exists and if so delete it before creating it.

Anybody tried to delete a partition with “intnvram” and can show me which parameters I have to use?

Thanks,

I found the solution myself:

intnvram set partition select=2 del

The order of parameters is evident. Maybe there should be a note in the docs.

Have a nice day,
