Subject: ARM: imx: linux-next 20191203 kernel does not start on an i.MX6ULL due to the SoC serial number fetch.
Date: Tue, 3 Dec 2019 10:59:41 +0000 [thread overview]
Message-ID: <1ef39c29b35d48cea0f8a98aabcfef29@dh-electronics.com> (raw)
Hi,
My i.MX6ULL SoC doesn't start on the linux-next 20191203 Kernel.
Reason is the commit "ARM: imx: Add serial number support for i.MX6/7 SoCs" (8267ff89b713).
For i.MX6ULL the variable "ocotp_compat" is set to "fsl,imx6ul-ocotp", but with commit
"nvmem: imx-ocotp: Implement i.MX6ULL/ULZ support" (ffbc34bf0e9c) and commit
"ARM: dts: imx6ull: Fix i.MX6ULL/ULZ ocotp compatible" (f243bc821ee3) the value
"fsl,imx6ull-ocotp" is already defined and set in device tree...
With the follwing change the kernel starts on my i.MX6ULL SoC.
