Hi,
My customer is using below environment.
SoC:66AK2G12
SDK:Processor SDK Linux 06_03_00_106
He tried to add scripts to launch their own application to below folders.
/etc/rc3.d
/etc/init.d
But scripts does not run until below message is displayed in console.
Application launch is delayed ~150 seconds.
[ 147.089976] random: crng init done
[ 147.093383] random: 7 urandom warning(s) missed due to ratelimiting
Customer found similar issue in old thread.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/787444/linux-am3359-crng-init-done-is-slow/2911764
This is for AM335x case, but it is not clear how it should be solved in 66AK2G12.
In below kernel dts files, RNG is defined.
arch/arm/boot/dts/keystone-k2e-netcp.dtsi
arch/arm/boot/dts/keystone-k2hk-netcp.dtsi
arch/arm/boot/dts/keystone-k2l-netcp.dtsi
sa_subsys: subsys@24080000 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "simple-bus";
ranges = <0 0x24080000 0x40000>;
sa_config: subsys@0 {
compatible = "syscon";
reg = <0x0 0x100>;
};
rng@24000 {
compatible = "ti,keystone-rng";
reg = <0x24000 0x1000>;
ti,syscon-sa-cfg = <&sa_config>;
clocks = <&clksa>;
clock-names = "fck";
};
};
But it is not in 66AK2G12 dts file (keystone-k2g-netcp.dtsi).
Customer tried to copy above definition to keystone-k2g-netcp.dtsi, but it just generates build error.
Thanks and regards,
Koichiro Tashiro
