Hi Stefan,

First of all, thanks to continue to investigate on this problem.

I've tried to increase the number of rx-packets and fixed it to 256.

The timeout still occurred but without the previous message MAL error occured.... ISR = c0100010 UIC = = 2 MAL_DEF = e0100000 MAL_ERR= e0000000 About preceeding transfer (eth0)

It's true that there is quite a lot of broadcoasts on the network, and I have the feeling that timeouts are less frequent this week as there is a lot of people on vacation (and so a lot of computer shutdown).

Perhaps it's a way to investigate.

Best regards

Olivier

Hi Olivier,

Yes, the behaviour changes with the network topology. On some switch, timeout occurs more often, but in the manufacturing center, we have an "island network", and it seems that the problem have not be reproduced.

Do you have lot's of broadcasts on your "main" network connection? Please try to increase the number of rx-packets again. For example:

#define CFG_RX_ETH_BUFFER 256

And please let me know if this helped. Thanks.

Best regards, Stefan
