Flashing custom iMX6ULL NAND flash using UUU tool

[asurti9]

Hello NXP team,

I have built the default YOCTO build for iMX6ULL, using build command as follows:

DISTRO=fsl-imx-wayland MACHINE=imx6ull14x14evk source imx-setup-release.sh -b build/

I have built all the images for core-image-minimal and I have a custom board adapted from iMX6ULL EVK and I need to check above images by downloading it to the NAND flash.

I found out there is UUU tool which can be used, however I am very new to the tool, can you please help me in getting step-by-step procedure to flash the device using NAND?

Thanks!

Hi, 

You can refer to uuu.pdf and using uuu tool to flash images. Release Release uuu_1.5.141 · nxp-imx/mfgtools · GitHub in which you will find examples for uuu for flashing nand device.

However, if you're intended to flash all images, might need to use the examples from samples/example_kernel_nand.uuu

try to download the prebuild image from the link: https://www.nxp.com/webapp/Download?colCode=L6.1.55_2.2.0_MX6UL7D&appType=license

then you will see the example_kernel_nand.uuu script for reference.

And yes, you can have a try the article (for legacy) that from our website.

Regards

Harvey

Hello Harvey,

I tried the suggested script "example_kernel_nand.uuu", but by running that script I am facing this error:

U>SDP: boot -f u-boot.imx-nand
>Start Cmd:SDP: boot -f u-boot.imx-nand
New USB Device Attached at 1:13
1:13>Fail HID(W):LIBUSB_ERROR_TIMEOUT(1.005s)
HID(W):LIBUSB_ERROR_TIMEOUT

I tried with the prebuilt u-boot (u-boot-imx6ull14x14evk_nand.imx) as well as the one which I built with my YOCTO package.

Can you please help me with this one?

EDIT:

Actually it does work at the first time, but the second command (no matter what), I fire, it is throwing the error:

Please input command: 
U>SDP: boot -f u-boot.imx

Have you tried uuu -b nand <your u-boot>? if you just flash U-Boot.

Hello,

When I try this command, then also I am getting following error:

Please also share the uart log and add parameter -v before -b then share log.

Please find the attached logs:

I have connected UART to the computer, but there are no logs there.

EDIT:

Can you please share the list of changes that need to be made under u-boot and kernel for booting from NAND? I have just added the below flag in `local.conf`

`UBOOT_CONFIG = "nand"`

Are there any further changes that need to be made?

Thanks!

[asurti9]

Hello @Harvey021 ,

Any update on this one?

EDIT:

I tried below command:

sudo uuu -v -V -pp 1 -b nand u-boot-nand-2023.04-r0.imx

I got below error:

I tried with the prebuilt nand u-boot as well, which you provided the link above. The result is the same.

Thanks!

[asurti9]

More info into it:

• I have added `UBOOT_CONFIG = "nand"` in local.conf
• We are using MT29F4G08ABAFAWP micron NAND, which I guess is supported by NXP
• I have not done any kernel side changes

[asurti9]

I have found this article - https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/How-To-use-NAND-boot-on-i-MX6UL-EVK-boar...

But it is for iMX6UL, will it be same for iMX6ULL?
