Subject: nvmem: imx-ocotp: fusing write tools
Date: Wed, 18 Dec 2019 11:10:59 +0100 [thread overview]
Message-ID: <2d527ebfde26459b7fa57e519610a8a5@agner.ch> (raw)
Hi,
We are looking to replace the NXP downstream OTP driver (CONFIG_FSL_OTP)
with the new upstream nvmem based driver. I was wondering if there is
user-space tooling around which can be used to write fuses. The NXP
driver had the fuse map as part of the API, so fusing was rather simple
and only required an echo into the right file. The new driver requires a
seek to the right offset.
I found this tool which provides fuse maps as yaml files and makes
fusing rather simple:
https://github.com/inversepath/crucible
At this point it seems to miss i.MX 8 series fuse maps. Also we so far
have no go runtime on our production system, we consider writing a
(probably simpler) C implementation thereof.
What is generally used to write fuses using the nvmem driver?
