RJ 08:42 AM Software Development: RE: Sending/Receiving Raw Ethernet Packets

I found this thread on the TI E2E site:

Looks like putting the switch in bypass mode should accomplish what I need to support promiscuou... Richard Joyce

You might try posting to the "TI E2E site":http://e2e.ti.com and seeing if they plan on supporting it, or if that have any work-arounds or pointers to how one might accomplish the promiscuous mode or capturing the raw packets.

Ah-ha ... I see I was layer too high!
The good news is I think you are correct about promiscuous mode...

Here would be another good place to look at what I'm trying to accomplish:

RJ 02:37 PM Software Development: RE: Sending/Receiving Raw Ethernet Packets

I may not be understanding correctly, but the page you sent is talking about IPv4 raw sockets. Using the protocol IPROTO_RAW. I am trying to communicate only on the Ethernet layer. I am not filling in an IP address. I am only using t... Richard Joyce

TI 01:11 PM Software Development: RE: Sending/Receiving Raw Ethernet Packets

Have you set the protocol number correctly, both in the packet and on the linux (335x in this case) machine? If the IPv4 stack cannot match the protocol # it will drop it (I believe).

RJ 11:55 AM Software Development: Sending/Receiving Raw Ethernet Packets

I am trying to write a Linux application for my MityArm 335x Dev board to send and receive raw Ethernet packets to/from a custom embedded board of our design. Our custom embedded board already successfully communicates with other boards... Richard Joyce

AS 03:13 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

Mike,
Thanks for the explanation and fast reply as usual. I think you're probably right that the mainline kernel isn't ready for prime-time. I guess the staging branch I found is going to stay in staging for quite some time until TI... Ali Asgar Sohanghpurwala

TC 08:27 PM PCB Development: RE: schematic of MityARM-3359

Thank you, Jason. I sent you an e-mail. Tom Thomas Catalino

JA 03:22 AM PCB Development: RE: schematic of MityARM-3359

Hello, Thomas
Could you also send me a copy of your MityARM 335X schematic to me ( PDF version and Altium format), we're very interested in your modules, and a HMI deivce project will be designed based on the modules.
Best Regards ... jason AK

MW 02:55 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

Hello Ali,
I've been watching TI and other folks working against the mainline kernel with AM335x, and it looks far from stable as compared PSP stuff -- though there is a lot of work going on in this area. This is primarily due to the... Michael Williamson

AS 01:19 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

Hello Mike,
I've been poking around some more with Angstrom 2012.05 and Qt5 on our Beaglebone development systems.
It looks like the arago kernel actually has a v3.2-staging branch for integrating AM33X support into the upstream ke... Ali Asgar Sohanghpurwala
