先把 eMMC 需要的兩個 profiles 先建起來

commit 52ad13e5222eceed4eb94965c5cbd672541d7860
Author: jeffrey <[email protected]>
Date:   Wed Nov 1 10:58:33 2017 +0800

    Add 2 profiles since we have additional storage choice - eMMC
    - 2 profiles in folder 'M300E' have 'PROSRC_EMMC=y'
    - the other profiles have '# PROSRC_EMMC is not set'
      - implicit means the storage choice is NAND Flash

emmc 的 uboot 的 bootcmd 做了下述這些事

mmc dev ${mmcdev};
mmc dev ${mmcdev};
mmc rescan;
setenv bootargs console=${console},${baudrate} root=${mmcroot}
fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${image}
fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} ${fdt_file}
bootz ${loadaddr} - ${fdt_addr};

各變數的值

${mmcdev} = 1
${console} = ttymxc0
${baudrate} = 115200
${mmcroot} = /dev/mmcblk1p2 rootwait rw
${mmcpart} = 1
${loadaddr} = 0x80800000
${image} = zImage
${fdt_addr} = 0x83000000
${fdt_file} = imx6ul-14x14-evk.dtb

如果要把 dual image a 帶起來需要

/dev/mmcblk1p1
- zImage_a
- dtb_a
/dev/mmcblk1p2
- rootfs_a

修改的 uboot env 變數如下

${image} = zImage_a
${fdt_file} = imx6ul-14x14-evk.dtb

把 dual image b 帶起來需要

/dev/mmcblk1p1
- zImage_b
- dtb_b
/dev/mmcblk1p3
- rootfs_b

修改的 uboot env 變數如下

${mmcroot} = /dev/mmcblk1p3 rootwait rw
${image} = zImage_b
${fdt_file} = imx6ul-14x14-evk_b.dtb

1300

參考目前的 uboot_env.sh

盤一下 EMMC 版本的 uboot env

1415

目前使用下述的 uboot env 已經可以順利的透過 no_good 來切換 dual image a 和 b

# only keep in uboot default
setenv app_1 'a'
setenv app_2 'b'



# dual image uboot env version
setenv uboot_env_ver emmc_v1.0



# common env
setenv mmcdev 1
setenv console ttymxc0
setenv baudrate 115200
setenv mmcpart 1
setenv loadaddr 0x80800000
setenv fdt_addr 0x83000000



# dual image no good counter

setenv no_good .



# dual image bootargs

setenv bootargs_a 'echo bootargs dual image a; \
setenv bootargs console=${console},${baudrate} root=/dev/mmcblk1p2 rootwait rw'

setenv bootargs_b 'echo bootargs dual image b; \
setenv bootargs console=${console},${baudrate} root=/dev/mmcblk1p3 rootwait rw'



# dual image fatload

setenv fatload_a 'echo fatload dual image a; \
fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} zImage_a; \
fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} imx6ul-14x14-evk_a.dtb;'

setenv fatload_b 'echo fatload dual image b; \
fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} zImage_a; \
fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} imx6ul-14x14-evk_a.dtb;'



# dual image app replace

setenv app_replace 'echo App Replace; \
if test ${app_1} = a; \
then echo App 1 from Dual Image a to b; setenv app_1 b; setenv app_2 a; \
else echo App 1 from Dual Image b to a; setenv app_1 a; setenv app_2 b; \
fi'



# dual image app choose

setenv app_choose 'echo App Choose; \
if test ${no_good} = ".xx"; \
then echo Replace App 1; run app_replace; setenv no_good .; \
else echo Run App 1; \
fi'



# dual image bootcmd emmc v1.0

setenv bootcmd_emmc_v1.0 'echo bootcmd_emmc_v1.0; \
mmc dev ${mmcdev}; \
mmc dev ${mmcdev}; \
mmc rescan; \
run app_choose; \
run bootargs_${app_1}; \
run fatload_${app_1}; \
setenv no_good ${no_good}x; \
saveenv; \
bootz ${loadaddr} - ${fdt_addr}'



setenv bootcmd 'run bootcmd_emmc_v1.0'

可以考慮先來 patch uboot

把剛剛透過 bitbake u-boot-imx -c compile 產生的 u-boot.imx

取代掉 manufacturing_tool\emmc\mfgtools\Profiles\Linux\OS Firmware\files\u-boot-imx6ulevk_sd.imx

燒吧

確認這樣的 uboot 已經可以把 rootfs_a 帶起來

而且在 uboot 透過把 no_good 設成 .xx 後

uboot 會自動切換到 rootfs_b

先把目前的成果做 commit 吧
