I'd like to bring attention to a shortcoming with the C66x multi-core DSP product folders, specifically for C6657 and C6678.
Let's look at C6657 as an example, when you go to the product folder https://www.ti.com/product/TMS320C6657 then tab your way to design and development then software development, you will see the BIOSMCSDK-C66X download
The NOTE shown there rightfully points out that the BIOSMCSDK-C66X is now superseded by the Processor SDK and says to See links above. However, there are -NO- links above. That's the problem, there are no links to the processor SDK. This same thing is true for the C6678 product folder.
For anybody reading this, I'm pasting in the links to the corresponding processor SDK's for these devices
I big improvement would be to add the processor SDK downloads to the product folders.
