how to compile Linux from the SDK ?

[dieselnutjob]

There is a "BSP Linux SDK ver 4.19 for Quartz64 model A SBC"  here https://wiki.pine64.org/wiki/Quartz64#BSP_Linux_SDK

But it isn't obvious how to use it.

So I had a guess.  I want Linux for a Quartz64 model A.

First I run ./envsetup.sh and it asks me to pick a "combo" out of 0-91.

Code:

62. rockchip_rk3566

looks good to me. So I go for that.

Then I run ./build.sh

it asks me

Code:

You're building on Linux
Lunch menu...pick a combo:

0. default BoardConfig.mk
1. BoardConfig-rk3566-evb2-lp4x-v10.mk
2. BoardConfig-rk3568-evb1-ddr4-v10-spi-nor-64M.mk
3. BoardConfig-rk3568-evb1-ddr4-v10.mk
4. BoardConfig-rk3568-nvr-spi-nand.mk
5. BoardConfig-rk3568-nvr.mk
6. BoardConfig.mk

Which one is a Quartz64 ?

Must be option 1 right? as it's the only option with RK3566

Code:

The same patch that I suggest here for Android https://wiki.pine64.org/wiki/Android_SDK_for_RK3566 seems to help with Linux too
