Can't I use the official master of Openwrt? Because all my software is based on openwrt official. Is there any good way?

[yipingwang]

I discussed with OpenWrt development team.

You could use master of Openwrt downloaded from https://github.com/openwrt/openwrt.git, which includes Linux Kernel 5.4.

However only the following release has been tested by NXP testing team.

tag: layerscape-20.09

Thank you very much for your answer. I will continue to test. thank you very much。

NXP’s community is very friendly.

I build from openwrt.
Cannot select ext4 file system. Will go wrong.
All others use the default parameter settings.

[yipingwang]

In OpenWrt squashfs is used for QSPI flash, ext4 is used by SD card.

Please refer to the following procedure to build SD image in OpenWrt.

$ git clone https://github.com/openwrt/openwrt.git

$ git checkout -b openwrt-19.07 origin/openwrt-19.07

$ make menuconfig

Please configure "Target System" as "NXP Layerscape", configure "Target Profile" as "LS1046ARDB (SD Card Boot))", then run make to  build the final image.

[suyunfa]

Thank you very much for your answers. For the time being, I have no better way.

I need kernel 5.4

The latest OpenWrt release from NXP is

Must it be openwrt-19.07? Doesn't it support master?
