Re: [PATCH] rockchip: rk3399: Add Nanopi M4V2 board support

2022-04-25 Thread Christopher Obbard
Hi Shuying Li & Libunko,

Would you be able to resend this patch to uboot mailing list ?

If you are no longer interested, I can resend it if you would like.

Thank you
Chris

right, I had to set ethaddr first in the environment...
The vendor u-boot seems to derive a default ethernet address from the
serial number.

Re: [PATCH] rockchip: rk3399: Add Nanopi M4V2 board support

2021-02-05 Thread Christopher Obbard
Hi!

I tested this patch, all working well apart from ethernet:

Model: FriendlyElec NanoPi M4V2
Net:
Error: ethernet@fe30 address not set.
No ethernet found.

Hit any key to stop autoboot:  0

=> nfs
mdio_register: non unique device name 'ethernet@fe30'
mdio_register: non unique device name 'ethernet@fe30'
mdio_register: non unique device name 'ethernet@fe30'
mdio_register: non unique device name 'ethernet@fe30'
No ethernet found.
mdio_register: non unique device name 'ethernet@fe30'


Any tips to get ethernet going ?

thinking about it, i should try a NanopiM4 V1...

thanks!

Hi All,
Shuying kindly pointed me to his branch:

git clone -b v2020.10.m4v2 https://github.com/Libunko/u-boot.git

What needs to be done to get this into mainline?

Re: [PATCH] rockchip: rk3399: Add Nanopi M4V2 board support

2020-11-02 Thread Kever Yang

Hi Shuying,

    I can't find a rk3399-nanopi-m4v2.dts at mainline kernel, does this 
a copy of rk3399-nanopi-m4.dts?


    What's the difference between m4 and m4v2, is it possible to use 
the same dts in U-Boot?


Thanks,
- Kever

Hope you sync the dts from Linux, if yes please add sha1 on the commit message.

The rest looks fine.
