Tool/software: Linux
Hi,
I am trying to boot Linux in my custom board having AM5716 SoC. My board has only serial port available to load binaries from outside. Linux Kernel image , ROOTFS created using busybox and Device Tree Blob is loaded into DDR via kermit protocol using loadb commands.
But when I try to boot using bootm command I am getting an error of Wrong Ramdisk image error.
=> bootm 0x82000000 0x88080000 0x88000000
## Booting kernel from Legacy Image at 82000000 ...
Image Name: Linux-4.9.59-ga75d8e9305
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 3752656 Bytes = 3.6 MiB
Load Address: a0008000
Entry Point: a0008000
Verifying Checksum ... OK
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid
Next I tried to include the rootfs along with linux kernel compiling , my kernel booting stops at :
[ 67.507216] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
[ 67.515525] ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
I have tried the steps in the link 
for creating RAMdisk.
Also tried using the steps in
Is it possible to get a compact root file system which I can send via UART to boot Linux in my custom board?
My console log is ::
