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