Error : No lease, failing

Naven,

Uniflash is supported on the CCS forum: https://e2e.ti.com/support/development_tools/code_composer_studio/f/81 Please ask there.

Naven,

The host PC is not providing a DHCP address. Can you capture a trace of the traffic with Wireshark?

Is it the 10th time exactly, or randomly 1 of 10 times will fail?

Hi RonB,

Thanks for reply .....

its fail randomly .

how can i solve this problem ??

 its urgent requirement for production.

Regards,

Naven

Naveen,

As requested by Ron could you please provide the wireshark logs as well ? You can download from the following link:

https://www.wireshark.org/download.html

Naveen,

Can you also provide the full logs of a failure or two? I am trying to determine whether USB is being used or not? Some things indicate that the board is attempting to use CPSW Ethernet and NOT USB. If Ethernet is not plugged in, obviously, this will fail. So, we need to figure out why USB is not being used as the interface. Or, if it is, why it is failing. Full logs will help me see this. The wireshark capture will help us see what is actually going on on the interface.

Hi RonB,

i run test capture wireshark when failure condition ,

please check attachment .

fail.txt

Naveen,

I'm sorry, the fail.txt file above doesn't seem to be a valid Wireshark capture file as I can't play it back in Wireshark. Could you try again? You have to stop the running capture, and then do a file save. That should give a capture file.

From what I can see above and some testing today, the "ifup usb0" which triggers udhcpc to get an address is failing. I can't tell why, though. That's what I hoped to see from the trace.

In your passing case, it looks like ethernet is up (over ethernet, not USB). Is that the case? What interfaces are connected when things work? Is it the same when things don't work?

I have seen where Uniflash on Windows misses packets because Windows is off doing something else. If that is the case, simply running udhcpc again might do the trick.

Hi RonB,

i send once agian wireshark file with zip can you check once .

and plan to check same test in linux pc ,but problem is i install uniflash tool in linux pc,

but problem is coustem board is not detecting in linux pc and how to configure ip address

please share details .

fail_filter.tar

Naveen

Naveen,

OK, that file works but unfortunately doesn't show anything useful. There is not BOOTP, DHCP, or TFTP traffic in that trace, that I can see.

Can you please share more info. about your setup? This process works best on a private network where the Host PC is directly connected to the board being flashed, either directly with a cable or through a switch. In your trace, there's a lot of other traffic. It could be because you captured all interfaces...

As for information to set up Linux Host networking with an AM335x board, please see here.
