i.mx8 Multisensory Enablement kit does not boot up

chrispinter — Tue, 25 Jan 2022 23:27:54 GMT

I received the Multisensory Enablement Kit and followed the Quick Start guide but the system does not look like it is booting up. I am following the quick start guide but will provide more details below.

I can see a number of LEDs on which tell me the system is powered.

D5 on

D4 on

D13 on

D8 on

D10 on

all other LEDs are off.

DIPS Switch is set to 001100 , which indicates it will boot from the SD card.

I have a Linux computer attached to the debug port and using CuteCOM to monitor all available USB port. I don't see any activity.

I have a monitor attached to the LVDS to HDMI Daughter board and it is attached to J2.

The quick start guide tells me I should see text on the debug port and something on the monitor.

I removed the SD card and check it had something on it and found a bootable linux configuration....So the SD Card looks like it should be able to boot.

I attached a photo of the board and SD card I received. Here are some details.

SD Card: MCIMX8QM-CPU Linux L4.14.62_1.0.0_BETA 110-78125 A

i.MX8 board serial number TDA8412

Very disappointing......

How can I troubleshoot? Do I need to return it?

Thanks,

Thanks, I saw the switch. I did not know what to do with it.

I turned the switch on and it looks like the display monitor is working.

I cannot communicate through the debug port. I am getting a "permission denied" window popping up.

Do you know anything about that?

you login with root/ no password is needed?

or you try this :

sudo su
//type your password
cd /
cd dev
chown username ttyUSB0

Thanks. This is the next step.

I am currently working on the UART Terminal. I was using Cutecom for Linux but it was buggy. It did not connect properly.

So I switched to my MAC computer and found "SerialTools" which was already installed from a previous project.

So I am good now.
