Hi All,

I have observed the kernel getting crashed after booting into kernel.. please provide the way to boot in to linux kernel..

please let me know what i am missing..

Background: porting from 4.9.59 kernel to 5.10.100(8.2.0.24 sdk) i have attached logs..

Hi Liu,

I am using am3352.. no we are not using GPU.. some how i modified dts file with respect to our requirement. and able to ablt to boot without crash.. but its observed that after "[ 133.728596] random: crng init done" no further kernel log is coming.

Hi Liu,

I am able to make the kernel up.. and we have used the KSZ8863 ethernet switch and can able to load the module.. while booting

1 issue i am facing is i am not able to ping from laptop to controller(custom controller which is based on am335x.

Note: i have modified dts (am335x-evmsk.dts) i.e as below (5.10.100 kernel version)

&phy_gmii_sel {
rmii-clock-ext;
};

initialy it was because we wer using 4.9.59 kernel

&phy_sel {

rmii-clock-ext;
};

will it be a problem while establishing connection? via ping?

Also 1 fundemnetal question: may i know who will be assigning ip for the controller?

please provide info at earliest..

Thank you

Hi Manu,

Networking is out of my expertise. I am routing your query to our Linux Ethernet expert for comments.
