Subject: ubiupdatevol read input from stdin or similar
Date: Thu, 2 Nov 2017 17:09:29 +0000 [thread overview]
Message-ID: <f46ce07819e74170a974bb7b0b5cddf1@itk-engineering.de> (raw)
Hello MTD Tools community,
I am searching for help on the usage of ubiupdatevol.
I am using ubiupdatevol version 1.5.2 and would like to pass input data from stdin or similar sources.
I hope to achieve something like the following line, where dd can be replaced by various other tools:
dd if=/dev/urandom | ubiupdatevol /dev/ubi10_1
However the above example always fails with the following error:
ubiupdatevol: error!: specify UBI device name and image file name as first 2 parameters (use -h for help)
However the commit ab8c6fb93ce9db0f09401c4b819b0b277dc00340 gives me the impression, that it could be done.
http://git.infradead.org/mtd-utils.git/commit/ab8c6fb93ce9db0f09401c4b819b0b277dc00340
However I cannot figure out how to make this work. If anyone has a code example I would be very grateful for your support!
Thanks and regards,
Martin Hollingsworth
