When will C6A816x be massively produced?

I heard that C6A816x will be massively produced by the end of 2011, is that right? It is a bit late.

What about the issue related to USB hub interface to USB port? Will this be resolved by back half of 2011?

Mahesh,

Yes, the USB hub issue will be fixed in the rev of the device which will be available in late 2011.

Marc--can you explain the USB hub issue?  We are using a Hub on one the USB Host ports on the DM8165.  Is there an issues with both host controllers or hubs or just some?  We are planning on using the SMSC2514.

I have not heard of any issues with Spectrum EVM boards and the use of USB hubs.  Will DM8165/8 silicon that properly supports USB hubs be available in small quantities for development of our hardware?

Bruce,

Here are the details of this hub issue, which affects both USB controllers.  These are found in the device errata.

Advisory 1.1.15 USB Host Mode Cannot Perform Write Operation to TxFunction/TxHubPort/TxHubAdr Controller Addresses
Revisions Affected: 1.1, 1.0
Details:  The USB controller does not support devices connected through a hub when operating as USB host. Due to this, writing to the TxHubPort/TxHubAdr results in the write being ignored.
Workaround:  There is no workaround for this issue. 

One other option is found here: http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_PCIeToUSB

Marc:

Can you point me to the DM8168 device errata?  I looked at the Spectrum side and did not see this.  This is a problem for us

I appreciate your help

Bruce

Bruce,

No problem - I'm sorry that you had not heard about this errata item.  The latest device documentation, including the errata, is found in the device product folder:

Thanks Marc

What are the chances this will be resolved in the next silicon and please confirm the timing for sample quantities?  We are looking at the PCIe option and alternately rolling the dice on a fix from TI. 

I am leaning towards the PCIe approach but using the DM8165 Host and Hub is preferred.

Bruce

Bruce,

Our confidence is very high that this issue will be fixed in PG2.0 of this device and samples are expected to be available in early 4Q11.

Marc

Would this change also apply to future AM3894 devices, and if so, do you have any idea about the schedule for such?   Lack of USB hub connectivity is painful for us and this is the first time I've seen any semi-official word that the Netra series is looking to resolve this limitation.

Yes, this fix also applies to the PG2.0 version of the AM389x devices, and it has the same schedule for its samples.

Regards,
Marc
