U-boot tests

Test Status
eMMC Enviroment saving OK
Sdcard Enviroment saving OK
Ethernet OK

Test Notes:

eMMC Environment saving

setenv serverip 192.168.2.93
saveenv
reset board
printenv serverip

Sdcard environment saving

Close the connector JM1:

setenv serverip 192.168.2.93
saveenv
reset board
printenv serverip

Ethernet

Once the serverip has been saved connect the board at J25:

setenv ipaddr 192.168.2.70
ping 192.168.2.161

The output should be:

Using enetc-0 device
host 192.168.2.161 is alive

Do the same test on port J26. The output should be:

Using enetc-1 device
host 192.168.2.161 is alive

Boot from eMMC

All switches positioned on OFF:

saveenv

The output should be:

Saving Environment to MMC... Writing to MMC(0)... OK

Boot from sdcard

Close the switch :

saveenv

The output should be:

Saving Environment to MMC... Writing to MMC(1)... OK

USB

Plug USB storage devices in J70/J71 connectors:

usb start

The output should be:

starting USB...
Bus usb@4c100000: Register 2000140 NbrPorts 2
Starting the controller
USB XHCI 1.10
Bus usb@4c200000: Register 2000140 NbrPorts 2
Starting the controller
USB XHCI 1.10

scanning bus usb@4c200000 for devices... cannot reset port 3!?
4 USB Device(s) found
       scanning usb for storage devices... 3 Storage Device(s) found

usb tree

The output should be (for example):

USB device tree:
  1  Hub (5 Gb/s, 0mA)
  |  U-Boot XHCI Host Controller 
  |
  +-2  Mass Storage (480 Mb/s, 100mA)
       Lexar USB Flash Drive AAGQFTGHNCK9GDXE

  1  Hub (5 Gb/s, 0mA)
  |  U-Boot XHCI Host Controller 
  |
  +-2  Hub (480 Mb/s, 2mA)
  | |
  | +-3  Mass Storage (480 Mb/s, 200mA)
  |      Verbatim STORE N GO 072125AD020B8F58
  |    
  +-4  Mass Storage (5 Gb/s, 224mA)
        USB  SanDisk 3.2Gen1 04010b53be303fea317bff34a9d8b86

Once done do:

usb stop

stopping USB..

to safely remove storage devices.

Serial Download

Close switch 4 to enable serial download. Connect the board with the source machine (i.e. the machine you are downloading the images from) by using the board's OTG header (N/A).

Power on the board.

From source machine check if an USB device for serial download is detected:

uuu -lsusb

Output:

uuu (Universal Update Utility) for nxp imx chips -- lib1.5.141

Connected Known USB Devices
        Path     Chip    Pro     Vid     Pid     BcdVersion      Serial_no

Here we see a device is detected. Then type:

uuu -v -b emmc_all imx-boot engicam-evaluation-image-mx95-imx95-smarcore.rootfs.wic

And wait for the download and flash of eMMC to finish.

Note

Note 1

Connect board's ethernet with your machine's one.

On your machine launch iperf3 server by typing:

iperf3 -s

On board launch iperf3 in client mode:

iperf3 -c 192.168.10.1

Using the IP address of your server machine.

Output:

Note 2

Connect TX/RX PIN connector J14 to the UART 232 port From terminal launch command:

test_serial ttyLP4

Verify that the characters written from keyboard are echoed in terminal.

Note 5

Set a time and date to the clock:

date -s "2024-01-01 12:00:00"
hwclock -w -f /dev/rtc1

Turn off the system and power it back on. Once it booted check that the date is the same:

hwclock -r -f /dev/rtc1

Note 6

Tested with command:

echo <n> > /sys/class/backlight/backlight/brightness

where n is an integer from 0 to 100

Note 7

Tested with command:

evtest /dev/input/event1

Note 8

Record an audio file with command:

arecord -d 5 -f S16_LE /tmp/test-mic.wav

then play and check with command:

aplay /tmp/test-mic.wav

Note 9

Connect J75 or J76 header to another board CAN header (or simply connect together J75 and J76 on the same board) and configure related can links on both ends of the connection:

End A:

ip link set can0 type can bitrate 125000

End B (for example on other board, can1):

ip link set can1 type can bitrate 125000

Enable interfaces on both ends:

End A:

ifconfig can0 up

End B (for example on other board, can1):

ifconfig can1 up

Make End A listen:

cantest can0

Send a frame from End B:

cantest can1 5A1#11.2233.44556677.88

Check output on End A:

read 16 bytes
5A1  [8] 11 22 33 44 55 66 77 88

Do the same from B to A (make B listen and A send a frame). When done on same board the command sequence is:

ip link set can0 type can bitrate 125000
ip link set can1 type can bitrate 125000
ifconfig can0 up
ifconfig can1 up
cantest can0 &
cantest can1 5A1#11.2233.44556677.88
sleep 1
cantest can1 &
cantest can0 5A1#11.2233.44556677.88

Note 10
