Embedded Programmer and Linux device driver developer

Tasks outlined:

1. we will provide source code and you extract on .tgz file
2. look over project materials, change source codes from nand to emmc uboot, buildroot and linux 3.10
3. create new environment to build image for flashing with phoenixsuit

4. Install and compile dependencies camera, wifi,
#Solve the problem of kImage generating zImage, or directly set lichee/brandy/u-boot-2014.07/tools to the environment variable PATH
sudo apt-get install -y u-boot-tools

5. modify & compile uboot, adjust sys config, for all relevant environments

self.target = target

MMC Support:
The MMC controller on the Intel PXA is supported. To
enable this define CONFIG_MMC. The MMC can be
accessed from the boot prompt by mapping the device
to physical memory similar to flash. Command line is
enabled with CONFIG_CMD_MMC. The MMC driver also works with
the FAT fs. This is enabled with CONFIG_CMD_FAT.

CONFIG_SH_MMCIF
Support for Renesas on-chip MMCIF controller

CONFIG_SH_MMCIF_ADDR
Define the base address of MMCIF registers

CONFIG_SH_MMCIF_CLK
Define the clock frequency for MMCIF

CONFIG_GENERIC_MMC
Enable the generic MMC driver

CONFIG_SUPPORT_EMMC_BOOT
Enable some additional features of the eMMC boot partitions.

CONFIG_SUPPORT_EMMC_RPMB
Enable the commands for reading, writing and programming the
key for the Replay Protection Memory Block partition in eMMC.


cd $CURRENT_PATH/lichee/brandy/
source build.sh -p sun8iw17p1

A. We will provide update sys config settings fex file

B. linux-3.10/drivers/media/platform/sunxi-vin/vin-mipi *photo & parameter settings*
IMX 35 func. https://github.com/SoCXin/H6/tree/master/linux/kernel/arch/arm/boot/dts

C. wifi
Put the linux4.9 driver provided by Quanzhi to the directory lichee\linux-4.9\drivers\net\wireless\xr829 and modify
lichee\linux-4.9\drivers\net\wireless\Makefile
lichee\linux-4.9\drivers\net\wireless\Kconfig
These two files, pay attention to the compatibility with the public version of the XR819 module, as follows:
-

7. Compile the kernel

First configure .buildconfig

cd lichee
./build.sh config

Welcome to mkscript setup progress

source build.sh

8. product img file and upload code on github


Requirements:
You need to be expert in Linux
know coding and put together kernels for pcb boards before
