Set up imx8 SCFW Porting Kit​ environment

1.Download the SCFW Porting Kit​

Download the SCFW Porting Kit​ according to the Linux Release​ from the following website

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applications-processors:IMXLINUX

2.Setup the cross compiler

Download and run the installer from launchpad.net/gcc-arm-embedded. https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

1.You can download the latest version cross-compiler gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2 from the site and decompression it to get the directory gcc-arm-none-eabi-9-2019-q4-major.

2.Create a new system environment variable and name it TOOLS.

The value of this variable should point to the Arm GCC Embedded tool chain installation path. For this example, the path is:

$ export TOOLS=/work/platforms/tmp/gcc-arm-none-eabi-9-2019-q4-major

3.Add DDR cfg file

Add the .cfg file to dcd directory from the DDR tool. https://community.nxp.com/docs/DOC-346060

For example: packages/imx-scfw-porting-kit/src/scfw_export_mx8qm_b0/platform/board/mx8qm_val/dcd/ROM7720_imx8qm_dcd_1.6GHz.cfg

4.Build SCFW Porting Kit

For the ROM-7720: $ make clean-qm $ make clean

Build the SCFW with debug message: $ make qm B=val D=1 M=1 R=B0 DDR_CON=ROM7720_imx8qm_dcd_1.6GHz

Build the SCFW with no debug message: $ make qm B=val D=0 M=0 R=B0 DDR_CON=ROM7720_imx8qm_dcd_1.6GHz

For the ROM-5620: $ make clean-qx $ make clean

Build the SCFW with debug message: $ make qx B=mek D=1 M=1 R=B0 DDR_CON=ROM5620_MX8QXP_B0_LPDDR4_2GB_RPA_1.2GHz_v12

Build the SCFW with no debug message: $ make qx B=mek D=0 M=0 R=B0 DDR_CON=ROM5620_MX8QXP_B0_LPDDR4_2GB_RPA_1.2GHz_v12

the output scfw_tcm.bin is the SCFW.
