Introduction
============
HiKey is the first certified 96Boards Consumer Edition board. The board/SoC has: -
* HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz.
* ARM Mali 450-MP4 GPU
* 1GB 800MHz LPDDR3 DRAM
* 4GB eMMC Flash Storage
* microSD
* 802.11a/b/g/n WiFi, Bluetooth
The HiKey schematic can be found here: -
https://github.com/96boards/documentation/blob/master/hikey/96Boards-Hikey-Rev-A1.pdf
A SoC datasheet can be found here: -
https://github.com/96boards/documentation/blob/master/hikey/
Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf
Currently the u-boot port supports: -
* USB
* eMMC
* SD card
* GPIO
Compile u-boot
==============
make CROSS_COMPILE=aarch64-linux-gnu- hikey_config
make CROSS_COMPILE=aarch64-linux-gnu-
ARM Trusted Firmware (ATF) & l-loader
=====================================
This u-boot port has been tested with l-loader, booting ATF, which then boots
u-boot as the bl33.bin executable.
1. Get ATF source code
git clone https://github.com/96boards/arm-trusted-firmware.git
2. Compile ATF I use the makefile here
http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/build-tf.mak
3. Get l-loader
git clone https://github.com/96boards/l-loader.git
4. Make sym links to ATF bip / fip binaries
ln -s /home/griffinp/aarch64/bl1-hikey.bin bl1.bin
ln -s /home/griffinp/aarch64/fip-hikey.bin fip.bin
arm-linux-gnueabihf-gcc -c -o start.o start.S
arm-linux-gnueabihf-gcc -c -o debug.o debug.S
arm-linux-gnueabihf-ld -Bstatic -Tl-loader.lds -Ttext 0xf9800800 start.o debug.o -o loader
arm-linux-gnueabihf-objcopy -O binary loader temp
python gen_loader.py -o l-loader.bin --img_loader=temp --img_bl1=bl1.bin
sudo bash -x generate_ptable.sh
python gen_loader.py -o ptable.img --img_prm_ptable=prm_ptable.img --img_sec_ptable=sec_ptable.img
These instructions are adapted from
https://github.com/96boards/documentation/wiki/HiKeyUEFI
FLASHING
========
1. Connect jumper J2 to go into recovery mode and flash l-loader.bin with
fastboot using the hisi-idt.py utility
> git clone https://github.com/96boards/burn-boot.git
> sudo python /home/griffinp/Software/hikey/burn-boot/hisi-idt.py -d /dev/ttyUSB0 --img1=/tmp/l-loader.bin
2. Once LED 0 comes on solid, it should be detected as a fastboot device
(on some boards I've found this to be unreliable)
sudo fastboot devices
3. Flash the images
wget https://builds.96boards.org/releases/hikey/nvme.img
sudo fastboot flash ptable ptable.img
sudo fastboot flash fastboot fip.bin
sudo fastboot flash nvme nvme.img
4. Disconnect jumper J2, and reset the board and you will now (hopefully)
have ATF, booting u-boot from eMMC. On 'new' boards I've had to do the
flashing twice in the past to avoid an ATF error.
See working boot trace below: -
debug EMMC boot: print init OK
debug EMMC boot: send RST_N .
debug EMMC boot: start eMMC boot......
load fastboot1!
Switch to aarch64 mode. CPU0 executes at 0xf9801000!
