My STM32MP157A-DK1 does not have an IP address, how to set it up?

[JWu.71]

I am learning STM32MP157A-DK1 according to the 'STM32 MPU wiki by ST' getting started steps, but I found that the IP query command didn't work like the tutorial say:

**************** Tutorial ********************

Board $> ip addr show eth0

3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

link/ether 00:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff

inet xx.xx.xx.xx/22 brd xx.xx.xx.xx scope global dynamic eth0

valid_lft 159045sec preferred_lft 159045sec

inet6 xx::xx:xx:xx:xx/64 scope link

valid_lft forever preferred_lft forever

***********************************************************

****** My board response***********************

root@stm32mp1:~# ip addr show eth0

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

  link/ether 00:80:e1:42:5d:ce brd ff:ff:ff:ff:ff:ff

  inet6 fe80::280:e1ff:fe42:5dce/64 scope link 

    valid_lft forever preferred_lft forever

***********************************************

See? The Underlined part is missing;

Without IP , I can't use the SW4STM32 to do the step “ Debug As > ST's STM32 MPU C/C++ Application�?

Does anyone have a solution to this problem? Thanks.

MAC address is defined in OTP and in your case it is 00:80:e1:42:5d:ce you see (it is programmed during board manufacturing)

IP address is defined by your network DHCP. Is your board connected to a network with a RJ45 cable ?

Thank you for your prompt reply !

My board is connected directly to my PC with a RJ45 cable, and the LED LD3 is blinking to indicate the data transmission. But IP is still unknown.:face_with_tears_of_joy:

[PatrickF · Accepted solution]

If your PC does not run a DHCP server, you could set manually the IP address using :

Board $> ifconfig eth0 uuu.***.yyy.zzz

(IP address should be set in an accessible range according to your PC IP and mask settings)

The command works!

Thank you very much.:D
