Upstream Integration #2

Open gregory-nutt opened 9 years ago

gregory-nutt commented 9 years ago

Hi, Kaushal,

I want to let you know that I am in the process up integrating your basic hub class into NuttX. This is still very much a work in in progress. It is on a branch here and will be for a while yet: http://sourceforge.net/p/nuttx/git/ci/usbhub/tree/

I did not include the ISP driver. My objective was different. I wanted to integrate your hub class into the existing NuttX HCD drivers. So I made many, many changes to get the hub compatible with the NuttX HCD interfaces as you see at the above link.

Hello Greg,

As you may have noticed, I haven't updated that repo for past few years. Essentially, we had to stop development as we had to start on something new and that looked like a big development cycle to build a product.

Anyway, good that atleast some part of that has to come to some use :o). The board and the design is still with us and working just that we have shelved that project. If anyone is interested in it we can give for further development.

By the way, I suppose this hub class will still be based on OHCI driver or has Nuttx got support for EHCI?

Regards Kaushal

Hi, Kaushal,

There was a person in the NuttX forum that expressed an interest in the ISP1761. If he is still interested, I will put him in touch with you.

Yes, there are several MCUs that now support EHCI. The modified version of your hub class should be compatible with any USB host implementation. But I will find out soon. as I continue testing.

Greg

PS: I do have it working now with an LCP1766 (OHCI) with a few bugs. But a lot more work is needed.
