Quick Start
|
|
===========
|
|
|
|
- Build the ARM Trusted firmware binary
|
|
- Get scfw_tcm.bin and ahab-container.img
|
|
- Build U-Boot
|
|
- Flash the binary into the SD card
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
======================================
|
|
|
|
$ git clone https://source.codeaurora.org/external/imx/imx-atf
|
|
$ cd imx-atf/
|
|
$ git checkout origin/imx_4.9.88_imx8qxp_beta2 -b imx_4.9.88_imx8qxp_beta2
|
|
$ make PLAT=imx8qxp bl31
|
|
|
|
Get scfw_tcm.bin and ahab-container.img
|
|
==============================
|
|
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-0.7.bin
|
|
$ chmod +x imx-sc-firmware-0.7.bin
|
|
$ ./imx-sc-firmware-0.7.bin
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.6.bin
|
|
$ chmod +x firmware-imx-7.6.bin
|
|
$ ./firmware-imx-7.6.bin
|
|
|
|
Copy the following binaries to U-Boot folder:
|
|
|
|
$ cp imx-atf/build/imx8qxp/release/bl31.bin .
|
|
$ cp u-boot/u-boot.bin .
|
|
|
|
Copy the following firmwares U-Boot folder :
|
|
|
|
$ cp firmware-imx-7.6/firmware/seco/ahab-container.img .
|
|
$ cp imx-sc-firmware-0.7/mx8qx-mek-scfw-tcm.bin .
|
|
|
|
Build U-Boot
|
|
============
|
|
$ export ATF_LOAD_ADDR=0x80000000
|
|
$ export BL33_LOAD_ADDR=0x80020000
|
|
$ make imx8qxp_mek_defconfig
|
|
$ make flash.bin
|
|
$ dd if=u-boot.itb of=flash.bin bs=512 seek=528
|
|
|
|
Flash the binary into the SD card
|
|
=================================
|
|
|
|
Burn the flash.bin binary to SD card offset 32KB:
