Description
- Building embedded Linux image for Zynq ARMv7 platform - Elphel 10393 board
About
- Yocto Poky revision = 2.0
- Host OS = Kubuntu 14.04.3 LTS x64
Required packages
- Found in Yocto Project mega-manual
Output files
Found in the poky's deploy directory: poky/build/tmp/deploy/images/
These names are listed as they appear in the u-boot configuration header file - actual output files have different names:
- boot.bin+(u-boot-dtb.img) - u-boot as the first stage bootloader = Secondary Program Loader that boots u-boot-dtb.img
- devicetree.dtb - device tree with described interfaces, zynq registers, interrupts and drivers
- uImage - kernel, drivers
- uramdisk.image.gz - applications
Copy them on the micro SD card (FAT partition) > run boot once in the u-boot command line.
Boot options
a. Auto unpacking the root file system image to RAM when booting.
Check u-boot default environment variables when building the bootloader.
Keep uramdisk.image.gz along with all the other files on the FAT partition of (micro)SD card.
