Amarula A64-Relic board has AP6330 WiFi/BT combo, but does not have ethernet port. So it makes sense to enable wireless networking by default: - add broadcom wireless firmware package to image - add basic wireless tools to image - add rootfs overlay with proper NVRAM file for on-board AP6330 chip - add mdev to image to enable module autoloading - update readme.txt to test wifi Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

Build
|
|
=====
|
|
|
|
$ make amarula_a64_relic_defconfig
|
|
|
|
$ make
|
|
|
|
build files at output/images/:
|
|
- sunxi-spl.bin
|
|
- u-boot.itb
|
|
- Image
|
|
- sun50i-a64-amarula-relic.dtb
|
|
- boot.vfat
|
|
- rootfs.ext4
|
|
|
|
Write eMMC
|
|
=========
|
|
|
|
The board comes with an operating system preloaded on the eMMC.
|
|
To replace it with the Buildroot-built system, take the following
|
|
steps
|
|
|
|
1. Connect the board UART with host and open minicom(ttyUSBx/115200N8)
|
|
|
|
2. Supply 12V DC for power-on the board.
|
|
|
|
3. Interrupt U-Boot by pressing enter
|
|
|
|
4. Create GPT partitions
|
|
=> mmc dev 1
|
|
=> gpt write mmc 1 $partitions
|
|
|
|
5. Connect the board USB-OTG with USB slot on the host.
|
|
|
|
6. Initiate fastboot
|
|
=> fastboot 0
|
|
|
|
7. Write images from host onto eMMC using fastboot
|
|
$ cd output/images
|
|
$ sudo fastboot -i 0x1f3a flash loader1 sunxi-spl.bin
|
|
$ sudo fastboot -i 0x1f3a flash loader2 u-boot.itb
|
|
$ sudo fastboot -i 0x1f3a flash esp boot.vfat
|
|
$ sudo fastboot -i 0x1f3a flash system rootfs.ext4
|
|
|
|
Update eMMC during Development
|
|
==============================
|
|
|
|
During development, reflashing the entire filesystem image at every
|
|
change is time consuming. A useful alternative is to directly access
|
|
over USB the filesystem stored on the eMMC, using the USB Mass Storage
|
|
capability of U-Boot. To achieve this:
|
|
|
|
1. Build U-Boot by enabling UMS
|
|
$ make uboot-menuconfig
|
|
(select CONFIG_CMD_USB_MASS_STORAGE=y)
|
|
|
|
2. Follow all 6 steps from 'Write eMMC' and mount eMMC on host
|
|
=> mmc dev 1
|
|
=> ums 0 mmc 1
