the grammar on uuu

[mm2021]

Could anybody give some documents about the grammar on uuu?

I know there is a document uuu.pdf, but still cannor find detailed explanation about details.

For example, in uuu.auto:

uuu_version 1.2.39

# What will the "boot" do?
SDP: boot -f imx-boot-imx8mmevk-sd.bin-flash_evk

SDPV: delay 1000

# what is the option "-skipspl" for?

SDPV: write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl
SDPV: jump

FB: ucmd setenv fastboot_dev mmc

#how to print the value of emmc_dev in uuu?

FB: ucmd setenv mmcdev ${emmc_dev}

Thanks!

@Zhiming_Liu Thank you very much for your reply, which helps a lot.

Here I still have some questions.

1. "boot -f imx-boot-imx8mmevk-sd.bin-flash_evk " is to load file imx-boot-imx8mmevk-sd.bin-flash_evk to RAM? And

"write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl" is to burn file imx-boot-imx8mmevk-sd.bin-flash_evk into mmc or sd card?

(How to choose mmc or sd card?)

2.

I try to use the following, but I still failed to get the value of emmc_dev:

FB: ucmd printenv emmc_dev
FB: ucmd printenv ${emmc_dev}

Thanks!

Hi

Q1:

write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl" is to burn file imx-boot-imx8mmevk-sd.bin-flash_evk into mmc or sd card?

(How to choose mmc or sd card?)

---->Can not choose device in this time.

Real flash happens in :FB: flash bootloader imx-boot-imx8mpevk-sd.bin-flash_evk

Q2:just use FB: ucmd printenv ,don't add other.

FB: ucmd printenv emmc_dev
FB: ucmd printenv ${emmc_dev}

[mm2021]

Maybe I should not keep at the printenv cmd. I just want to modify to flash uboot & kernel into sd card instead of eMMC. The following auto file is for eMMC, how to change to sd card?

uuu_version 1.2.39

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f imx-boot-imx8mmevk-sd.bin-flash_evk

SDPV: delay 1000
SDPV: write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl
SDPV: jump

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev ${emmc_dev}
FB: ucmd mmc dev ${emmc_dev}
FB: flash -raw2sparse all imx-image-multimedia-imx8mmevk.wic
FB: flash bootloader imx-boot-imx8mmevk-sd.bin-flash_evk

FB: ucmd if env exists emmc_ack; then ; else setenv emmc_ack 0; fi;

FB: ucmd mmc partconf ${emmc_dev} ${emmc_ack} 1 0

FB: done

[Zhiming_Liu]

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev ${sd_dev}
FB: ucmd mmc dev ${sd_dev}
FB: flash -raw2sparse all _rootfs.sdcard
FB: flash bootloader _flash.bin
FB: done

[mm2021 · Accepted solution]

Thanks for the instant reply!

But seems that the flash to sd card script need these two files:
_rootfs.sdcard
_flash.bin

How to use the the two files (in my uuu auto script) to flash into sd card, instead of eMMC?
imx-boot-imx8mmevk-sd.bin-flash_evk
imx-image-multimedia-imx8mmevk.wic

I change like this?

uuu_version 1.2.39

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f imx-boot-imx8mmevk-sd.bin-flash_evk

SDPV: delay 1000
SDPV: write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl
SDPV: jump

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev ${sd_dev}
FB: ucmd mmc dev ${sd_dev}
FB: flash -raw2sparse all imx-image-multimedia-imx8mmevk.wic
FB: flash bootloader imx-boot-imx8mmevk-sd.bin-flash_evk

FB: ucmd if env exists emmc_ack; then ; else setenv emmc_ack 0; fi;

FB: ucmd mmc partconf ${sd_dev} ${emmc_ack} 1 0

FB: done

Thanks!

[mm2021]

Using sd_dev, will flash into sd card;

Using mmc_dev, will flash into eMMC.

Hope it is useful for others.

[mm2021]

sorry. mmc_dev should be emmc_dev

[Zhiming_Liu]

Hi

Yes,just replace the bootloader and image

[mm2021]

Seems I still cannot get the value from printenv(but return ok, but no value printed). Please check the auto file here:

uuu_version 1.2.39

# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f imx-boot-imx8mmevk-sd.bin-flash_evk

SDPV: delay 1000
SDPV: write -f imx-boot-imx8mmevk-sd.bin-flash_evk -skipspl
SDPV: jump

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev ${emmc_dev}

#FB: ucmd printenv emmc_dev
#FB: ucmd printenv ${emmc_dev}
FB: ucmd printenv

FB: ucmd mmc dev ${emmc_dev}
#FB: flash -raw2sparse all imx-image-multimedia-imx8mmevk.wic
#FB: flash bootloader imx-boot-imx8mmevk-sd.bin-flash_evk

FB: ucmd if env exists emmc_ack; then ; else setenv emmc_ack 0; fi;

FB: ucmd mmc partconf ${emmc_dev} ${emmc_ack} 1 0

FB: done

And this is the log I get when I execute "uuu uuu.auto":
