[OrangePi Zero Plus: ethernet in u-boot]

Hello all,

The board has a 2MB NOR FLASH chip what would be enough for storing u-boot and booting the system over network. Unfortunately u-boot says there is no ethernet.

Is there anybody who knows how to enable ethernet on this or similar board like OPi PC2 or Nanopi NEO2?

Is it just a matter of configuration or is RTL8211E as PHY generally not supported on H5 chips?

Thank you very much for your help.

[OPZero SPIdev usage]

Thank you very much!

Yes, applying overlay Dt of SPI1 works now and /dev/spidev1.0 is accessible. Using flashcp I can write u-boot to SPI FLASH. Also applying SPI overlay in u-boot works now.

[OPZero SPIdev usage]

Hello everybody

 

I know that mainline kernel isn't supported for OPi zero yet...

 

When enabling both SPI by applying an overlay DT I get an error saying that PA15 is already in use by a LED.

 

Searching the dts files I found that OPi zero dts includes OPi one/light dts. In OPi one/light there is SPI0 on header pins and SPI1 is used as UART3, GPIO and status LED.

 

Is there a way to disable the LED in the overlay DT? Or do I have to patch OPi zero dts?

Hello armbian community

 

I'm also interested in this topic. So far I found following links describing FEL boot:

 

https://docs.armbian.com/Developer-Guide_FEL-boot/

http://linux-sunxi.org/FEL/USBBoot

 

I managed to load kernel, initrd and dtb to RAM (all files from /boot of armbian image):

 

sunxi-fel uboot u-boot-sunxi-with-spl.bin write 0x43300000 uInitrd write 0x42000000 zImage write 0x43000000 sun8i-h3-orangepi-pc.dtb

 

And start the kernel:

 

bootz ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

 

Right now there are no kernel parameters so it hangs in initramfs.

 

 

Anybody who managed to NFS boot OPi PC without SD-card?
