uuu script hanging with new u-boot version

Hi,

we're using a uuu script to transfer data to an imx8mm on a custom board which is then used by u-boot (mainline u-boot v2025.01) to flash an EEPROM / program some imx8mm fuses.

However, after migrating from u-boot 2020.07 to 2025.01, the script now hangs.

The uuu script we're using is:

uuu_version 1.0.0

SDP: dcd -f "flash-sd-v2025.01+git999-r0.bin"
SDP: write -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0
SDP: write -f "EEPROM.bin" -addr 0x00810000
SDP: jump -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0
SDP: delay 3000
SDP: boot -f "flash-sd-v2025.01+git999-r0.bin" <= NOT EXECUTED
SDP: delay 2000
SDP: dcd -f "flash-sd-v2025.01+git999-r0.bin"
SDP: write -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0             <= ERROR reported

SDP: jump -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0

uuu output is as follows:

PS D:\_data> ./uuu.exe -t 10 -T 10 uuutest.txt
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.201-0-g727fc2b
 
Success 0    Failure 1
 
 
2:7-         9/20 [HID(W): LIBUSB_ERROR_IO (-1)          ] SDP: write -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0

While the error is reported for 'write -f "flash-sd-v2025.01+git999-r0.bin" -ivt 0', it seems it is already not executing 'boot -f "flash-sd-v2025.01+git999-r0.bin"'.

With the old u-boot version, the script fully ran through.

I tried to figure out what the boot command actually does (and what it expects), but the documentation on the SDP commands in https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/imx-processors/140261/1/UUU.pdf seems to be limited...

I re-checked that I've enabled all relevant u-boot CONFIGs according to UUU.pdf, so I guess this should be an issue.

The last step that is executed in u-boot before the SDP boot command is

restore_boot_params();

So, I thought maybe it's an issue with a different definition of this function. However, this ASM function in arch/arm/mach-imx/imx8m/lowlevel_init.S seems to be exactly the same for the new u-boot version.

So, does anybody have an idea what could be missing / wrong?

Also, does anybody know of more documentation on the SDP commands?

Kind regards,

Markus

Hi Aldo,

we're building u-boot using our custom Yocto recipe, since we also need AT-F.

The image is normally booting (when using it on SD card rather than in SDP mode).

For the moment we have decided to stay with the old u-boot version (mainline v2020.07) for the flashing/fusing using uuu scripts in production.

Anyway, thanks for your support so far!

Kind regards,

Markus

Hello,

Could you share the latest Uboot version that was working using your script?
Please try running the script with verbose mode activated (-V)
Also, is there any messages on the console?

From what you have shared seems that it isn't but want to double check with you.

Best regards/Saludos,
Aldo.

Hi Aldo,

thanks for your response!

The latest u-boot version that worked was mainline u-boot v2020.07 with our custom code on top (mainly board definition).

No, no error messages on the console. We're getting the SPL "banner" message and then, our custom messages, but since we don't get the banner for the 2nd start we conclude that the boot loader isn't started again.

Ok, will try with verbose mode activated.

Kind regards,

Markus

Not sure why there are descriptor errors coming. However, they're also coming for our u-boot v2020.07:

Could it be an issue with the uuu version? I guess the uuu.exe we're using is a little older...

Kind regards,

Hello,

It may be worth trying with latest version just to be sure that there is no issues with the version you are using.

About the errors you are seeing, if you are using a HUB or other devices are connected then this could be the reason of the messages.

Also, I would suggest to try to re build you boot image, since it is failling to start at the very beggining meaning that the boot image is not correct.

Best regards/Saludos,
Aldo.

Hi, I tried with the latest release binary from https://github.com/nxp-imx/mfgtools/releases/tag/uuu_1.5.201, but no difference (actually it seems, I already had used the latest version).

There is no USB hub involved (apart from the USB root hub in my laptop).

Also, I have re-built u-boot and tried again, but it made no difference.

Kind regards,

Markus

Hello,

Could you share how are you building your uboot binary?
Usually for i.MX8M familly processors it is required to create a boot binary, so if you are building in standalone mode it requires some extra steps.


Best regards/Saludos,
Aldo.

Hi Aldo,

we're building u-boot using our custom Yocto recipe, since we also need AT-F.

The image is normally booting (when using it on SD card rather than in SDP mode).

For the moment we have decided to stay with the old u-boot version (mainline v2020.07) for the flashing/fusing using uuu scripts in production.

Anyway, thanks for your support so far!

Kind regards,

Markus
