U-Boot for the Gateworks i.MX8M Mini Venice Development Kit boards
|
|
|
|
Quick Start
|
|
===========
|
|
- Build the ARM Trusted firmware binary
|
|
- Get ddr firmware
|
|
- Build U-Boot
|
|
- Flash to eMMC
|
|
- Boot
|
|
|
|
Get and Build the ARM Trusted firmware
|
|
======================================
|
|
$ git clone https://source.codeaurora.org/external/imx/imx-atf
|
|
$ git checkout imx_5.4.47_2.2.0
|
|
$ make PLAT=imx8mm CROSS_COMPILE=aarch64-linux-gnu- bl31
|
|
$ cp build/imx8mm/release/bl31.bin .
|
|
|
|
Get the DDR Firmware
|
|
====================
|
|
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
|
|
$ chmod +x firmware-imx-8.9.bin
|
|
$ ./firmware-imx-8.9.bin
|
|
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .
|
|
|
|
Build U-Boot
|
|
============
|
|
$ make imx8mm_venice_defconfig
|
|
$ make CROSS_COMPILE=aarch64-linux-gnu-
|
|
|
|
Update eMMC
|
|
===========
|
|
=> tftpboot $loadaddr flash.bin
|
|
=> setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200
|
|
=> mmc dev 2 && mmc write $loadaddr 0x42 $blkcnt # for IMX8MM
|
|
=> mmc dev 2 && mmc write $loadaddr 0x40 $blkcnt # for IMX8MN
