|
===========
|
|
- Build the ARM Trusted firmware binary
|
|
- Get ddr firmware
|
|
- Build U-Boot
|
|
- Boot

|
Get and Build the ARM Trusted firmware
|
|
======================================
|
|
$ git clone https://source.codeaurora.org/external/imx/imx-atf
|
|
$ cd imx-atf
|
|
$ git checkout imx_4.19.35_1.0.0
|
|
$ make PLAT=imx8mq bl31
|
|
$ cd ..
|
|
