uuu: an in-depth description for script commands

[IgorKorolyuk]

Hello.

I'll have to bring up an iMX.8MDualCore based board soon, so I've been investigating tools to do that and discovered the UUU manual (UUU.pdf) to be quite poor on what those script command actually do. There are lots of user manual of how to run uuu to get a certain reference board flashed in a number of ways, but I've seen none describing uuu script commands in technincal details. ("SDPV: write -f _flash.bin -skipspl -scanterm" : what are all the options here? what is _flash.bin file format is expected to be?)

Is there an in-depth technical description for those commands? If there is, where can I get one?

Here is a link to a doc that does provide some detail on the individual commands of each protocol in the uuu script.  https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.4.165/UUU.pdf

There is also another forum topic that provided this link and might be useful for those writing custom script https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Creating-and-running-a-custom-script-for...

_flash.bin stands for uboot bin file, you can replace this name to your own uboot bin file name

joanxie,

Thanks for the tip on this particular example but it's not full enough.

• What are those two other command options?
• The command is "write", right? Ok. What's the destination address? How does the uuu figure that out?

See, this sort of questions arise on all of the commands in script file, not just this particular one. That's why I'm asking for in-depth description on all of them.

I don't know what you mean, you can find example uuu script file like "example_kernel_emmc.uuu" which is attached in the demo images,you can just replace your own image name

you also can refer to detailed source code and readme:
