PROCESSOR-SDK-AM335X: AM3358

Part Number: PROCESSOR-SDK-AM335X

Tool/software:

I'm trying to use the beaglebone blk to genreate the USB test patterns.  In this post  from 9 years ago, the OP talks about the procedure he followed to get the processor to generate the patterns.  

Where can I find this procedure now that the processors.wiki.ti.com site is no more ( assuming it was there)?

I'm not a S/W, so I'm looking for something that walks me through using menuconfig, enabling the kernal debugfs, etc.  

Hopefully this is part of the procedure....

Thank you
