LS1021A_TWR uboot source code

[free_will]

Hi,

  I am using LS1021A TWR board for development. But after read the pdf file Layerscape Software Development Kit User Guide(Supports: LSDK 19.09-update-311219), i could not find the method to get uboot source code of this board. 

1. How can I get the uboot source code of this reference board? 

2. Below pic shows download link of linux kernel source code,  is it the linux kernel source code of LS1021A_TWR?

pls help me confirm above question, thank you very much.

In flex-build build environment, please run the following command, you will get u-boot source in 

flexbuild_lsdk1909_update_311219/packages/firmware/u-boot

$ source setup.env

$ flex-builder -c u-boot -m ls1021atwr

Please refer to the following command to get u-boot source code manually.

$ git clone http://source.codeaurora.org/external/qoriq/qoriq-components/u-boot

$ cd u-boot

$ git checkout -b LSDK-19.09-update-311219 LSDK-19.09-update-311219
