AM62P: Kernel falcon cannot boot with tiny initramfs

Cong Pham
Intellectual 590 points
Part Number: AM62P
Other Parts Discussed in Thread: AM625

Tool/software:

Dear TI experts,

We use falcon boot mode for AM62P custom board

We follow the boot sequence suggested by TI:

We follow the instructions in this link: 4.1.9. Boot Time Optimizations — Processor SDK AM62Px Documentation

1. With the tiny-initramfs from TI Processor SDK 10.01.10.04

As the result, it goes to the log in console but stuck there. We cannot log in with user "root"

2. With the tiny-initramfs built from yocto

The tiny-initramfs that built from yocto have the different name and size in comparation with the prebuild one from TI SDK

When we use this tiny-initramfs, it failded to mount Huge Pages File System. 

The strange thing is that when we tried to use the rootfs from another project that used the AM625, it worked well.

Could you let us know where we might be making a mistake?

Note: We use MCU+ SDK 11.00.00.16

Processor SDK Linux 10.01.10.04

Thanks,

Cong.

    Before building the kernel image, have you provided all permissions to the cpio filesystem?
    If not, first give it chmod 777 permissions, and then build the kernel image.

    sudo chmod -vR 777 <filesystem>/*
