| Compile: |
| |
| export PATH=<path-to-toolchain>/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-elf/bin:$PATH |
| export CROSS_COMPILE=aarch64-elf- |
| git clone https://gitlab.com/baylibre/amlogic/atv/u-boot.git |
| cd u-boot |
| git checkout u-boot/v2019.10/sei610-20190905-fix |
| make [sei510|sei610]_defconfig |
| make |

| Generate fip binary |
| =================== |
| |
| use tarball in fip_packages folder and untar it |
| |
| - For sei510 (yukawa_sei510): |
| tar -xaf fip-collect-g12a-g12a_u200_v1-amlogic-dev_9.2.1811_21-20191203-113239.tar.gz |
| |
| - For sei610 (yukawa): |
| tar -xaf fip-collect-g12a-sm1_ac214_v1-amlogic-dev_9.2.1811_21-20191204-161855.tar.gz |
| |
| - For VIM3L (yukawa): |
| tar -xaf fip-collect-sm1-kvim3l-khadas-vims-v2015.01-20191204-095738.tar.gz |
| |
| Then launch script: |
| |
| ./generate-bins-new.sh <fip-collect-directory> <target-bl33-binary> |
| |
| flash result with: |
| fastboot flash bootloader uboot-bins/u-boot.bin |
| fastboot erase bootenv |
| fastboot reboot bootloader |
| |
| after reboot if partitions table need to be updated: |
| fastboot oem format |
| |
