I am using the DM816x/C6A816x/AM389x Evaluation Module
The uboot parameters can be modified using a generated minicom script that starts as follows:
timeout 300
verbose on
expect {
"stop autoboot:"
}
send ""
... rest of script.
However although the "Hit any key to stop autoboot:" string does appear the script doesn't appear to see it.
A bit of experimentation showed that the string only seemed to be recognised when a CR/LF was issued.
CR/LF doesn't get issued in this case presumably because the count down probably uses backspaces or CR.
Changing the script to recognise the line before and putting in a delay works but is there a better way?
I did try to use /c at the end of the string but this had no effect.
