Subject: Re: [PATCH] images: ignore i.MX signed (USB) images and outputs of imx-csf tool

Message-ID: <0dfe3495603bae2becd0ed6223b6e048c6a43c76.camel@pengutronix.de> (raw)

Hi,

Yes and no. CSF (Command Sequence File) is the input format for the
cst, however the cst outputs a csf binary blob containing the
certificates, signatures and the required sequence of commands for the
bootrom.
.csfbin is the correct name either way because barebox uses these
filenames as an intermediate step before appending the csf binary blob
to the image:

$ ls images/*csfbin
images/start_nxp_imx8mq_evk.pblb.simximg.csfbin
$

I think changing the filename would not make much sense, since the
csfbin still contains the same sequence of commands, albeit in a binary
form with additional data attached.

Hope this helps,
Rouven Czerwinski
