Fail to get file via tftp on DM8147 EVM board

 

Hi everyone.

 

I have 8167 evm made by MISTRAL and dm8168 evm. and I have DVR SDK and EZSDK as well.

I could not get file via tftp on 2stage bootloader status. When trying, the following messages is shown, I can not understand why it was not working.

This error happens on both of 8167 evm and 8168 evm 

 

TI8148_EVM#tftp

link up on port 0, speed 100, full duplex

Using cpsw device

TFTP from server 192.168.2.137; our IP address is 192.168.2.204

I have tried it using both of  static IP and DHCP and both of bootloader in EZSDK and DVR SDK's . Always I got same error.

 

Of course, our tftp server installed on linux machine is working well. There was no problem when trying it with dm6446 device.

 

Somebody could give me a advice?

 

  • Hi Choi JinYong

    If there is heavy multicast trafic in the network, then there are chances of CPSW dropping packets as only 4 DMA Rx descriptors are used in U-Boot.

    Can you try with the following patch. The patch increases the DMA Rx descriptors to 16.
