Enable network in Zako's UEFI firmware #97

Open anatol opened 6 years ago

anatol commented 6 years ago

I am using a Zako for UEFI firmware development. I found that this ChromeOS box is a great and non-expensive way to do development.

I am trying to get SimpleNetworkProtocol UEFI protocol that allows to access the underlying network hardware from my UEFI app. My code works in QEMU but at Zako it returns EFI_NOT_FOUND error. That I interpret as UEFI firmware does not have support for Zako ethernet chip.

Could you please enable network support for Zako in the UEFI fw?

UEFI driver from the vendor might help here. See the vendor download site section "UEFI UNDI Driver".

Could you please release a test firmware for Zako or share some instructions how to modify your existing UEFI firmware and add a new network driver?

I'll have to look into this, as it would require adding both the UEFI networking stack as well as the device-specific driver

Thank you very much Matt. I am eager to help to test the functionality.

Here is an example of integrating Realtek driver into the build, maybe Zako could have something similar? https://github.com/tianocore/edk2-platforms/blob/devel-MinnowBoardMax-UDK2017/Vlv2TbltDevicePkg/PlatformPkg.fdf see section under "Network Modules".
