1. Hardware Setup

Prepare hardware as described below:

...

1. Set up the Boot switch on the IMXRT1170-EVK board for SDP: set SW1 as 0001 and re-enable the power supply.

2. On the development host run the Secure Provisioning Tool. In the New Workspace window, select the MIMXRT1176 processor and click Create:

   

3. Run the Flash Programmer tool: click Tools->Flash Programmer menu or press Ctrl+R. Answer yes in the pooped up window:

   

4. Click the Load button, select the imxrt1170_demo.img from the file system and confirm Load:

   

5. Make sure the Auto erase and Auto verify check-buttons are set and the click the Write button:

   

6. Wait until the write operation is completed:

   

7. When the writing is completed, close the MCUXpresso Secure Provisioning Tool. Then set up boot jumpers on the target board to boot from QSPI Flash: set SW1 as 0010, SW2 as 0000000000.

8. Use your preferable serial communication tool to connect to the target serial console (we use picocom in this demo):

   Code Block

   $ picocom -l -b 115200 /dev/ttyACM0 picocom v3.1 port is : /dev/ttyACM0 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 stopbits are : 1 escape is : C-a local echo is : no noinit is : no noreset is : no hangup is : no nolock is : yes send_cmd is : sz -vv receive_cmd is : rz -vv -E imap is : omap is : emap is : crcrlf,delbs, logfile is : none initstring : none exit_after is : not set exit is : no Type [C-a] [C-h] to see available commands Terminal ready

9. Power cycle the board. U-Boot and then Linux should start automatically on the serial console:

   Code Block

Ethernet Driver Support

1. In the target serial console configure the eth0 interface manually (using the ifconfig and route plagins of busybox), or start the DHCP client to apply the networking settings from a DHCP server:

   Code Block

   / # udhcpc Micrel KSZ8081 or KSZ8091 40424000.ethernet-1:00: attached PHY driver (mii_bus:phy_addr=40424000.ethernet-1:00, irq=POLL) fec 40424000.ethernet eth0: Link is Up - 100Mbps/Full - flow control off / # ifconfig eth0 eth0 Link encap:Ethernet HWaddr AA:BB:CC:DD:EE:F0 inet addr:192.168.1.74 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:2 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:796 (796.0 B) TX bytes:684 (684.0 B) / #

2. From the development host validate that the target board is visible using ping:

   Code Block

   $ ping -c5 192.168.1.74 PING 192.168.1.74 (192.168.1.74) 56(84) bytes of data. 64 bytes from 192.168.1.74: icmp_seq=1 ttl=64 time=0.632 ms 64 bytes from 192.168.1.74: icmp_seq=2 ttl=64 time=0.305 ms 64 bytes from 192.168.1.74: icmp_seq=3 ttl=64 time=0.297 ms 64 bytes from 192.168.1.74: icmp_seq=4 ttl=64 time=0.288 ms 64 bytes from 192.168.1.74: icmp_seq=5 ttl=64 time=0.298 ms --- 192.168.1.74 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4112ms rtt min/avg/max/mdev = 0.288/0.364/0.632/0.134 ms $

3. From the target board, validate that it is connected to the internet using ping:

   Code Block

   / # ping -c5 example.org PING example.org (93.184.215.14): 56 data bytes 64 bytes from 93.184.215.14: seq=0 ttl=57 time=122.202 ms 64 bytes from 93.184.215.14: seq=1 ttl=57 time=122.158 ms 64 bytes from 93.184.215.14: seq=2 ttl=57 time=121.991 ms 64 bytes from 93.184.215.14: seq=3 ttl=57 time=122.116 ms 64 bytes from 93.184.215.14: seq=4 ttl=57 time=122.105 ms --- example.org ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 121.991/122.114/122.202 ms / #
