Image cannot be burnt to emmc with UUU tool for iMX8mm board

[hongtao_li]

Hi support,

I am bringing up a board with iMX8mm CPU, I want to boot from the emmc, but I cannot burn the image to it with UUU tool. It stops as below.

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.127-4-g1b0e385

Success 0 Failure 0

1:2 1/ 1 [=================100%=================] SDP: boot -f ../image-boot-L5.4/fsl-imx8mm-evk.bin

Is the bootloader not correct? What should I modify in the SPL and uboot?

Thanks.

Thans Joan, it is resolved now.

[joanxie]

where did you get the images? your own build or demo images? and what download command do you use? share with me your download steps, let me check it

[hongtao_li]

Hi Joan,

Thanks your reply. The image is compiled by myself. Attached is the script I use to flash the emmc.

[joanxie]

did you use customized board or nxp imx8mm evk board, if nxp board, do you mind downloading the demo images, and use "uuu.exe uuu.auto" to test again?

Hi Joan,

I used our own customized board. I have no NXP EVK board but have an i.MX8mm EVK board of other company. And they use this  command "uuu.exe uuu.auto" to flash their image successfully. 

[joanxie]

is fsl-imx8mm-evk.bin your bootloader file? how did you get this? I couldn't confirm this according to this name, or maybe you can try the command as below to download uboot to the board to check if your board can boot up or not

$ sudo dd if=<U-Boot image> of=/dev/sdx bs=1k seek=<offset> conv=fsync

• 32 - for i.MX 8QuadXPlus B0, i.MX 8QuadMax B0, i.MX 8DualX, i.MX 8DXL, i.MX 8M Nano, i.MX 8M Mini, and i.MX 8M Plus

[hongtao_li]

Yes, fsl-imx8mm-evk.bin is my bootloader including spl,uboot, atf and ddr firmware.

The dd command is executed in kernel, right? So how can I run it? Because I am in the serial download mode and there is no any image on the boot device, such as emmc.

[joanxie]

you also can use "uuu -b spl fsl-imx8mm-evk.bin" to download the uboot to the board, how about the result? dd command is for loading the only uboot image to the board

Hi Joan,

Can you please help to check my log below? Is there any configration change in uboot for emmc boot?

Hi Joan,

We found something wrong with our hardware design, which leads the CPU to enter TEST MODE.

After fixing it ,when I run the command "uuu -b spl  fsl-imx8mm-evk.bin", the log is as below.

[joanxie]

because you only flash uboot image to the board, so you get the information about "Unknown image format!", since your uboot is available, you can use the command as below to flash images to your board

"uuu -b emmc_all <bootloader> <rootfs.wic>" the bootloader is fsl-imx8mm-evk.bin
