2.3 Buildroot File System and Linux Kernel
Start the build operation using the $ make command from the
buildroot-at91 directory.
This $ make command displays the build status on the
terminal.
Note: Ensure that the host PC is
connected to the internet before starting the build operation, and do not use any build
options.
The following files are generated in the
The driver source files are located at:
buildroot-at91/output/images directory when the build operation is
completed.| File Name | Description |
|---|---|
| sama5d4_xplained.itb | Image Tree Blob – Contains zImage, base device tree along with dt-overlays |
| rootfs.ubi | The root file system includes the WILC modules by default |
| at91-sama5d4_xplained.dtb | Device tree Blob file for SAMA5d4_xplanined board |
| u-boot.bin | U-boot for Microchip SoC (aka AT91) |
| uboot-env.bin | U-boot environment |
| sama5d4_xplained_wilc_sdio.dtso | WILC SDIO dt-overlay |
| sama5d4_xplained_wilc_spi.dtso | WILC SPI dt-overlay |
| sama5d4-nandflashboot-uboot-4.0.5.bin | AT91Bootstrap binary and is 2nd level bootloader for Atmel AT91 SoC |
