Hi,
Currently I am working on an embedded project using Nvidia’s jetson TK1 board. I have builded up the customized linux kernel and u-boot through Yocto project. The Linux kernel version is 4.7
During startup I am seeing some error messages related to the cpu clock frequency, Can you please let me know what you think about the following error messages:
[ 0.000000] Tegra clk 127: register failed with -17
[ 0.075752] /cpus/cpu@0 missing clock-frequency property, len:-301236472
[ 0.080664] /cpus/cpu@1 missing clock-frequency property, len:-301236472
[ 0.087453] /cpus/cpu@2 missing clock-frequency property, len:-301236472
[ 0.094185] /cpus/cpu@3 missing clock-frequency property, len:-301236472
[ 0.977039] +USB0_VBUS_SW: Failed to request enable GPIO108: -517
And I am interested to know in which file the cpu clock frequency is set.
I have looked into the files in the kernel source … /drivers/clk/tegra , but couldn’t able to locate the file responsible to set the clock frequency
