[Additional Information]
I check the device node on /dev/ there’s no tee node can be found. I add tegra194-optee.dts in dts, but take no effect. Please help to take a look. thanks. 5003956_a90df1f8af_dmesg.txt (175.5 KB)
Hi Jerry, thanks for reply:
There is no /dev/tee0 or /dev/teepriv0.I change dts like this.
firmware {
optee {
compatible = “linaro,optee-tz”;
method = “smc”;
status = “okay”;
};
};
Then I get the error in kernel:
[Sat Dec 14 15:23:36 2024] optee: probing for conduit method.
[Sat Dec 14 15:23:36 2024] optee: api uid mismatch
