Still problems with network on the ARM - STM32F7 - Nucleo-144 board

Hi

I have still problems with my nucleo-144 board (stm32F746ZG) and the 
network.

I've tried both static and dynamic IP.

The eth0 doesn't receive an IP from the DHCP server (still 0.0.0.0).

When I give

nsh> ifup etho

I get the message

ifup eth0...OK

but the card is still down

nsh> ifconfig

eth0    Link encap:Ethernet HWaddr 5e:11:f1:23:d9:ce at DOWN
     inet addr:0.0.0.0 DRaddr:192.168.178.1 Mask:255.255.255.0

when I launch:

nsh> renew eth0

I get

ERROR: dhcpc_request() failed

What is wrong in my configuration? (attached

Hi Roberto,

I did a test with stm32f746g-disco using the default netnsh board
profile and it got IP:

$ ./tools/configure.sh stm32f746g-disco:netnsh

$ make

Connect a mini-usb cable to CN14 USB-STLINK

$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32f7x.cfg -c
init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"

$ minicom -s

Change /dev/ttyUSB0 to /dev/ttyACM0

NuttShell (NSH) NuttX-10.3.0-RC2
nsh> ifconfig
eth0    Link encap:Ethernet HWaddr 00:e0:de:ad:be:ef at UP
        inet addr:10.42.0.68 DRaddr:10.42.0.1 Mask:255.255.255.0

nsh> ps
  PID GROUP PRI POLICY   TYPE    NPX STATE    EVENT     SIGMASK   STACK COMMAND

nsh>

Maybe you can compare it with your board config to see what is missing.

BR,
