How to update 3 imx6ull via SDP in parallel

[cb1]

Hello,

I want to load SPL and uboot via serial downloader protocol (SDP) to 3 imx6ull devices in parallel. Each download must be independent from the other.

I got it running with the imx_usb tool. Unfortunately this tool works only under Linux, but I need to run it under windows.

I found out, that there is a tool called uuu which works on windows.

Downloading only the SPL works fine. Therefore I am using the following uuu.auto "script":

uuu_version 1.0.1

SDP: boot -f SPL-spi
# This command will be run when use SPL
SDPU: delay 1000
SDPU: write -f SPL-spi
SDPU: jump‍‍‍‍‍‍‍

Now I am trying to extend above "script" to also get the uboot downloaded via SDP and started.

Can anyone help me how to extend the script above?

Does uuu support updating 3 devices in parallel?

Thanks!

Hello,

Have you tried the built-in script in the tool?

uuu -b spl bootloader

This script download spl and uboot to your target.

As for your question regarding parallel programming as far as I know it is not possible one could run UUU in Daemon mode. This option is used to flash multiple boards of the same type, one after another.

Also, if possible take a look to the UUU git for more information about examples and general information

Hope this helps,
