DHCP with WIZnetInterface-OS5

Hi, I'm using mbed with WIZnetInterface-OS5. Trying to run DHCP via:

source

WIZnetInterface eth;
uint8_t mac_addr[6] = {0x00, 0x08, 0xDC, 0x00, 0x01, 0x02}; 
eth.init(mac_addr);
eth.connect();
printf("IP Address: %s\r\n", eth.getIPAddress());

I get this output on the console:

source

[int DHCPClient::setup(int):197]m_retry: 0
[int DHCPClient::setup(int):197]m_retry: 1
[int DHCPClient::setup(int):197]m_retry: 2
[int DHCPClient::setup(int):207]m_retry: 3, m_interval: 5672
IP Address: 0.0.0.0

I see no DHCP packets via wireshark.

Note: my hardware is ok, using a static IP address works fine.

Any help? Thanks!

Hi Jonathan, check the Mbed os5 version, your platform is indicating up to 5.6. You may have to switch back to that version or even try os2.

I tried rolling back but I get the following error:
