Booting the DM355 DVEVM Board under Ubuntu 9.10

Mikhail Smagin

Dear Friends, I have a problem and hope for your help. I want to connect the DM355 DVEVM board to PC and begin to work with it. I've connected the Board to PC via COM-port and Ethernet. The PC is working under WinXP and I've made the Virtual Machine and installed Ubuntu 9.10 on it.

In Ubuntu I've installed all the applications and made appropriate settings according to the: http://processors.wiki.ti.com/index.php/GS...Setup_in_Ubuntu. Problems begin, when I meet the "Testing the Shared File System" part.

The Board starts, and I can control boot process using the Minicom terminal. Following the instruction, I interrupt the boot and enter additional settings. Afterwards I continue the boot. It reaches the DHCP request stage, can not connect with PC and goes on perpetual cycle of looking for DHCP reply and asking for IP-address.

Restarting of DHCP Service in Ubuntu and disabling of Firiwalls both in Ubuntu and WinXP doesn't help. I've tried to write the IP-settings manually, but it also doesn't help. The Board shows "Kernel Panic" message that RPC does not recieve the answer from the appropriate port.

I've checked the cables, but they are OK. I have no ideas. Please help.

Thank you in advance.

    Can you verify nfs by using some other system to check whether it is configured properly. Also, I hope you have configured the virtual machine's network interface as 'bridged adapter'.  I had seen problems with 'NAT' configuration for network.

    Thank you very much. Bridged adapter mode solved the problem.
