uClinux for Blackfin Release Checklist

This sheet includes all Blackfin related features and default configurations in the uClinux release package. Include kernel features, applications and uClibc setting. These features must be checked before a code freeze.

Blackfin Related Kernel Features

  1. CPU type (BF531/2/3/4/6/7/, BF561, BF522/4/7, BF544/8/9)
