Hi,

I am trying to boot the j1nx builds from SD card or NFS at my amlogic M3 box .
But, I meet the problem with following logs

This is the same situation....

noggin fixed it for his box, you might try that.

~~j1nx~~ · 2013-01-31, 08:02

You don't give much info about your specific compile parameters do you? Anyway, looking at the info you do give: You try to mount an ext3 partirion as yaffs.

noggin · (This post was last modified: 2013-01-31, 10:52 by noggin.)

I forked the j1nx buildroot-AmLogic stuff, edited /etc/fstab and S10setup in init.d to remove all yaffs2 stuff (as I'm using NFS for my entire fs), and also edited s10setup to leave filesystems rw. I tar-ed the rootfs.tar to my NFS share.

I compiled my kernel with different NAND settings to j1nx's.

Will try and sync my current build with my github repo tonight in case it helps. It may take a while to read my thread but all the info is in there that got my box to work to a degree (ircodes aren't mapping and my USB requires a powered hub to work...)

First, I'm trying NFS booting.

But, my M3 board is stopped with kernel panic while kernel is loading.
Problem is NFS mount fail.
I found the reason of NFS mount fail.
My board LAN LED is off after kernel loading.
I guess that LAN driver isn't loaded.

How can I solve it?

ps : Lan chip(MAC?) of my board is LAN8720.
I builded with default amlogic_f16ref_gbox-xbmc_defconfig.

I find the reason of my board ethernet problem.
My board use the internal clock for ethernet but reff16 use the external clock.

I success .....

Thank you for help....

I will test that it have some problem...

Be a good guy and share what you have done / changed with the others on this board. I know for sure others will also want to know what you did to get eth working...

My board configuration is

clk81 = 200M --> bootargs ( I found it at console log. )

/buildroot-AmLogic/output/build/linux-db...../arch/arm/mach-meson3/board-m3-reff16-gbox.c

//#define NET_EXT_CLK 1 --> I block this define.

My board use the internal clock for ethernet.
If your board have ethernet problem then try it....

That's all.
