i.MX6ULL系统移植：uboot移植2 - 移植NXP官方uboot

2021-07-21 00:01:28  阅读：315  来源： 互联网

标签：rw uboot NXP onlylove -- mx6ull DATA 移植


在移植过程中按照NXP官方文档《i.MX BSP Porting Guide》和正点原理提供资料均未移植成功，最后通过一个大佬博客讲解成功移植。以此记录。
原博客地址：https://blog.csdn.net/BBDS1ASD/article/details/108692727

一、解压NXP提供uboot

tar -vxjf uboot-imx-rel_imx_4.1.15_2.1.0_ga.tar.bz2

二、添加开发板配置文件

在uboot/configs/中，把mx6ull_14x14_evk_emmc_defconfig拷贝成自己的mx6ull_14x14_xxx_emmc_defconfig；

cp mx6ull_14x14_evk_emmc_defconfig mx6ull_14x14_xxx_emmc_defconfig

修改mx6ull_14x14_xxx_emmc_defconfig内容：

CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6ull_xxx_emmc/imximage.cfg,MX6ULL_EVK_EMMC_REWORK"
CONFIG_TARGET_MX6ULL_xxx_EMMC=y

三、添加开发板头文件

有一些需要配置的信息，一般是在一个头文件里面配置，每个板子有一个。对于NXP官方的6ULL EVK板子，这个头文件就是mx6ullevk.h.
在uboot/include/configs/中，把mx6ullevk.h 拷贝成自己的 mx6ull_xxx_emmc.h；

修改mx6ull_xxx_emmc.h内容：

#ifndef __MX6ULLEVK_CONFIG_H
#define __MX6ULLEVK_CONFIG_H

改为

#ifndef __MX6ULL_XXX_EMMC_CONFIG_H
#define __MX6ULL_XXX_EMMC_CONFIG_H

四、添加开发板的板级文件夹

每个板子都有特有的文件，也叫做板级文件；这里我们将6ULL EVK的板级文件直接拷贝过来。
在 uboot/board/freescale/ 中，将 mx6ullevk/ 文件夹拷贝成自己的板级文件夹 mx6ull_xxx_emmc/；

cp mx6ullevk mx6ull_xxx_emmc

五、调整板级文件夹中文件内容

1、更改C文件名

在新的板级文件夹中，将mx6ullevk.c拷贝成mx6ull_xxx_emmc.c；

mv mx6ullevk.c mx6ull_xxx_emmc.c

2、修改Makefile

obj-y := mx6ull_xxx_emmc.o

3、修改imximage.cfg

PLUGIN board/freescale/mx6ullevk/plugin.bin 0x00907000

改为

PLUGIN board/freescale/mx6ull_xxx_emmc/plugin.bin 0x00907000

4、修改Kconfig

if TARGET_MX6ULL_xxx_EMMC

  config SYS_BOARD
	default "mx6ull_xxx_emmc"
  config SYS_VENDOR
	default "freescale"
 config SYS_SOC
	default "mx6"
  config SYS_CONFIG_NAME
	default "mx6ull_xxx_emmc"

endif

5、修改MAINTAINERS

MX6ULL_XXX_EMMC BOARD
M: Peng Fan <peng.fan@nxp.com>
S: Maintained
F: board/freescale/mx6ull_xxx_emmc/
F: include/configs/mx6ull_xxx_emmc.h
F: configs/mx6ull_14x14_xxx_emmc_defconfig

六、修改uboot的配置界面

修改文件arch/arm/cpu/armv7/mx6/Kconfig，添加如下内容：

config TARGET_MX6ULL_xxx_EMMC
 	bool "Support mx6ull_xxx_emmc"
 	select MX6ULL
 	select DM
 	select DM_THERMAL

source "board/freescale/mx6ull_xxx_emmc/Kconfig"

七、编译

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- mx6ull_14x14_xxx_emmc_defconfig
make V=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4

八、测试

1、解压uboot

tar -vxjf uboot-imx-rel_imx_4.1.15_2.1.0_ga.tar.bz2

解压前：

onlylove@ubuntu:~/linux/uboot/nxp_uboot$ ls
uboot-imx-rel_imx_4.1.15_2.1.0_ga.tar.bz2
onlylove@ubuntu:~/linux/uboot/nxp_uboot$

解压后;

onlylove@ubuntu:~/linux/uboot/nxp_uboot$ ls
uboot-imx-rel_imx_4.1.15_2.1.0_ga  uboot-imx-rel_imx_4.1.15_2.1.0_ga.tar.bz2
onlylove@ubuntu:~/linux/uboot/nxp_uboot$

2、添加开发板配置文件

cd uboot-imx-rel_imx_4.1.15_2.1.0_ga/configs/
cp mx6ull_14x14_evk_emmc_defconfig mx6ull_14x14_lq_emmc_defconfig

命令执行前：

onlylove@ubuntu:~/linux/uboot/nxp_uboot/uboot-imx-rel_imx_4.1.15_2.1.0_ga/configs$ ls -l mx6ull*

5、调整板级文件夹中内容

1、更改C文件名

mv mx6ullevk.c mx6ull_lq_emmc.c

2、修改Makefile

修改前：

# (C) Copyright 2015 Freescale Semiconductor, Inc.
#
# SPDX-License-Identifier:	GPL-2.0+
#

obj-y  := mx6ullevk.o

extra-$(CONFIG_USE_PLUGIN) :=  plugin.bin
$(obj)/plugin.bin: $(obj)/plugin.o
	$(OBJCOPY) -O binary --gap-fill 0xff $< $@

修改后：

3、修改imximage.cfg

#endif

4、修改Kconfig

修改前：

if TARGET_MX6ULL_14X14_EVK || TARGET_MX6ULL_9X9_EVK

config SYS_BOARD
	default "mx6ullevk"

config SYS_VENDOR
	default "freescale"

config SYS_CONFIG_NAME
	default "mx6ullevk"

endif

修改后：

if TARGET_MX6ULL_LQ_EMMC

  config SYS_BOARD
	default "mx6ull_lq_emmc"
	
  config SYS_VENDOR
	default "freescale"
	
 config SYS_SOC
	default "mx6"
	
  config SYS_CONFIG_NAME
	default "mx6ull_lq_emmc"

endif

5、修改MAINTAINERS

修改前：

MX6ULLEVK BOARD
M:	Peng Fan <peng.fan@nxp.com>
S:	Maintained
F:	board/freescale/mx6ullevk/
F:	include/configs/mx6ullevk.h
F:	configs/mx6ull_14x14_evk_defconfig
F:	configs/mx6ull_9x9_evk_defconfig

修改后：

MX6ULL_LQ_EMMC BOARD
M: Peng Fan <peng.fan@nxp.com>
S: Maintained
F: board/freescale/mx6ull_lq_emmc/
F: include/configs/mx6ull_lq_emmc.h
F: configs/mx6ull_14x14_lq_emmc_defconfig

6、修改uboot配置界面

cd arch/arm/cpu/armv7/mx6/
vim Kconfig

在 207 行加入如下内容：

config TARGET_MX6ULL_LQ_EMMC
 	bool "Support mx6ull_lq_emmc"
 	select MX6ULL
 	select DM
 	select DM_THERMAL

在最后一行的 endif 的前一行添加如下内容：

source "board/freescale/mx6ull_lq_emmc/Kconfig"

7、编译

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- mx6ull_14x14_lq_emmc_defconfig
make V=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4

部分编译信息：

Image Type:   Freescale IMX Boot Image
Image Ver:    2 (i.MX53/6/7 compatible)
Mode:         DCD
Data Size:    425984 Bytes = 416.00 kB = 0.41 MB
Load Address: 877ff420
Entry Point:  87800000

8、烧录到SD卡

sudo dd if=u-boot.imx of=/dev/sdb bs=1k seek=1 conv=fsync

烧录结果：

onlylove@ubuntu:~/linux/uboot/nxp_uboot/uboot-imx-rel_imx_4.1.15_2.1.0_ga$ sudo dd if=u-boot.imx of=/dev/sdb bs=1k seek=1 conv=fsync

9、将SD卡插入开发板进行验证
