I started a custom board port a couple of weeks ago from SDK v6 to v8. Not an easy jump as v8 included a major Linux update (4.10 to 5.10). I recently found out the AM335x SDK v9 is due out shortly (in a few months). Is there a pre-release available? I'd prefer to not to do another full port in a few months; just an incremental to the official release. Thank you.
