BiTDB with OP-TEE Support (based on the project raspbian-tee)

Introduction

This project discribed how to integrating BiTDB on Raspbian Pi 3B.

Dependence

• Host OS: Ubuntu 16.04 or later.
• Cross Build Toolchain: AARCH64 & AARCH32 both needed, and AARCH32 must > 6.0. (you can get one from linaro)
• Hardware: Raspberry Pi 3B board.

Build

First, config your cross build toolchain at config.mk.

Then:

$ ./prepare-env.sh # if your had download all packages, skip this.
$ make patch # this will patch linux kernel & ATF, if you have done before, skip this.
$ make

If you meet the follow issue:

/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here
collect2: error: ld returned 1 exit status

Please edit the file /linux/scripts/dtc/dtc-lexer-lex.c and /u-boot/scripts/dtc/dtc-lexer-lex.c Find the line 'YYLTYPE yylloc' and change it to 'extern YYLTYPE yylloc'. (Reference: https://lkml.org/lkml/2020/4/1/1206 and BPI-SINOVOIP/BPI-M4-bsp#4)

When success, it should seem as:

  ......
  INSTALL sound/usb/hiface/snd-usb-hiface.ko
  INSTALL sound/usb/misc/snd-ua101.ko
  INSTALL sound/usb/snd-usb-audio.ko
  INSTALL sound/usb/snd-usbmidi-lib.ko
  DEPMOD  4.14.98-v7
make[1]: Leaving directory '/***/raspbian-tee/linux'
cp /***/raspbian-tee/linux/arch/arm/boot/uImage ./out/boot/
cp /***/raspbian-tee/linux/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dtb ./out/boot/
cp /***/raspbian-tee/linux/arch/arm/boot/dts/bcm2710-rpi-3-b.dtb ./out/boot/
cp /***/raspbian-tee/firmware/config.txt ./out/boot/

Install

Prepare a SD Card Flashed with an official Raspbian image (2019-06-20-raspbian-buster.img), mount it in linux, such as /media/user/boot & /media/user/rootfs.

Then:

$ cp ./out/boot/* /media/user/boot
$ sudo cp -r ./out/rootfs/* /media/user/rootfs

Boot Rsapberry Pi with the Modified image in SD Card.

When you are logined,then:

$ ls /dev/tee*
/dev/tee0 /dev/teepriv0 # this prove tee driver & optee-os works.
$ sudo tee-supplicant &
$ sudo optee_example_bitdb tpc #this will run a TPC-H test, you need to put TPC-H-small.db in /home/pi

It should be no errors, then all is OK.
