To begin with, the name 'Nitrogen6W' is deprecated. We used it on our first i.MX6 Nitrogen boards and were planning to build Nitrogen6 (no Wireless and no W) separately. Our intent was that Nitrogen6 with no W would be 100% compatible with SABRE Lite. Our plans have changed, and we've decided to use the same design with and without a wireless module using the same design. We'll also be adding a Nitrogen6S (Solo) and perhaps Nitrogen6DL (Dual-Lite) option using the same design with slightly different BOMs. I see some e-mails from Otavio and Daiane that ask further questions about Nitrogen6X and SABRE Lite. I'll respond to those separately and elaborate on the product differences. Now on to the questions... Otavio has already pushed support for Nitrogen6X into meta-freescale. How does your patch differ from that? Is it We should definitely re-fresh Otavio's patch. In particular, there are a few recent patches on our 'boundary-L3.0.35_12.09.01_GA' branch that dramatically improve performance under high (>400Mbps) ethernet load. https://github.com/boundarydevices/linux-imx6/commits/boundary-L3.0.35_12.09.01_GA I believe that this one also is the trick to getting camera input working with our Nit6x_5MP parallel camera module: https://github.com/boundarydevices/linux-imx6/commit/1c382d81eef3c4ab60a392b260f3d54871e38f2b Are there any other updates in this patch set? Since it's one big un-differentiated patch, it's difficult to tell whether there are other updates. Please advise, Eric
