I work with thw Viola Board V1.2B and use an i.MX6ULL with the Image:Colibri iMX6ULL (2.8b4 | 2018-10-05)
The UART connection the the terminal on the Linux Host works fine.
Problem:
I cannot stop the U-Boot with any key on boot phase ?
What can be the reason ? (Ii seems do be no hardware problem, because Terminal works fine with UART)
hi @StefanR
Could you provide the version of the hardware of your module?
Please share also a picture of your setup (Uart connection) ? Thanks.
You could also try to increase the boot delay with the following command from linux:
fw_setenv bootdelay 10
Best regards, Jaski
Set the hardware flow control to “No” in minicom
Thanks for you Input.
@StefanR: Did this solution work?
I don’t know if it worked for the person who asked this question, but for me it worked perfectly with my Apalis and iMX6 board. Thanks a lot
Perfect that it works. Thanks for your Input.
I also have an issue with this. Something similar, but mine is stuck at the kernel (…because it’s bad)
The problem is I can’t get to stop the u-Boot before to change the environment (bootdelay) either to reflash the image … because of the process… it’s not finishing…
I did a try with the minicom - “hardware flow control - No”
But nothing happened…
Should I press repeatedly a button or holding it or keystrokes maybe or ??
Any comment may help! I would very appreciate in advance!
HI @r4nd3l and Welcome to the Toradex Community!
Could you ask a new Question and provide a serial boot log in text format?
Thanks and best regards,
Jaski
