Re: No ethernet card with Olimex Lime 2

Hi 

Thanks for your responses ! 

I tried your solutions, it still doesn't work. 

From the beginning I use the instructions here : 
http://wiki.netbsd.org/ports/evbarm/allwinner/#index1h2 and the 
http://dl.linux-sunxi.org/nightly/u-boot-sunxi/u-boot-sunxi-mainline/u-boot-sunxi-mainline-latest/u-boot-sunxi-mainline-a20-olinuxino-lime.tar.xz U-boot 
build. 

When I boot, the uEnv.txt is not recognized since I have to enter manually the 
command in the U-boot prompt, and the root=ld0a is not passed to the kernel 
(it demands me what is the root partition). 

After the first response, I tried the FEX script solution. Using the 
instructions at http://wiki.netbsd.org/ports/evbarm/allwinner/#index6h1 I 
downloaded the script https://raw.githubusercontent.com/linux-sunxi/sunxi-boards/master/sys_config/a20/a20-olinuxino_lime2.fex and compile it with 
fex2bin (on an amd64 Linux machine) and put it on the msdos partition on the 
sdcard. Then I enter in the U-boot prompt : 

setenv bootargs root=ld0a sysconfig=0x43000000 
fatload mmc 0:1 43000000 a20-olinuxino_lime2.bin; fatload mmc 0:1 82000000 
netbsd.ub; bootm 82000000 

It boots without asking me for root partition but I have no ethernet : 

# dmesg | grep awge 
awge0 at awinio0: Gigabit Ethernet Controller 
awge0: interrupting on irq 117 
awge0: reset timed out 
awge0 at awinio0: Gigabit Ethernet Controller 
awge0: interrupting on irq 117 
awge0: reset timed out 

I think I'm doing something wrong in the process but I don't see where. 
The system is compiled on a amd64 NetBSD-7 machine. The u-boot-sunxi-with- 
spl.bin is written on the beagleboard.img, and the image is written on the 
sdcard on amd64 Linux machine. Does it matter ? 

Thanks again for your responses.
