Hello,

There is 30 seconds holding system by kernel-5.30.-rc4-dev (rockpro 64) Why does it happen?

[ 0.004114] printk: bootconsole [uart8250] disabled -->> no response..

With mainline U-BOOT it boots fast (but can't be rebooted)

[SeongwoongKim1976]

It's not boot area but kernel. The first stage happened after boot area is complete.

[ 0.003716] printk: console [tty0] enabled [ 0.004114] printk: bootconsole [uart8250] disabled -->> no response.. The system is holding for 20 ~ 30 seconds. Rockchip is probably waiting for something during 30 seconds..

[rox4d]

I suppose CPU is slow at that moment and this a reason of delay, and initial frequency of CPU are setted by bootloader.

[SeongwoongKim1976]

I don't change the frequency of CPU..

[rox4d]

It is by default low, and cpufreq will change it at later boot (but i may be mistaken).

[SeongwoongKim1976]

After downloading and compiling the kernel from ayufan https://github.com/ayufan-rock64/linux-kernel/releases/tag/4.4.202-1237-rockchip-ayufan and update..

I chose the kernel-4.4.193-rockchip-dev, but [ 0.003716] printk: console [tty0] enabled [ 0.004114] printk: bootconsole [uart8250] disabled -->> no response.. The system is holding for 20 ~ 30 seconds. and reboot.. Why?

[rox4d]

Possible something wrong with your kernel or ramdisk and in practice it was 1: kernel-5.3.0-rc4-dev boot.

[pfremm]

Did you ever fix this? I have same issues.
