Developments:

1. Exposed vring to userspace using misc device which provides streaming data from pru to arm.

2. Proper code alignment and commenting. Not completed yet.

Issue:

Blocking read on misc device still facing synchronization issues. This involves correcting flow of pending buffer interrupts sent by PRU->ARM and their subsequent transfer to userspace by copy_to_user.

Next Week:

Wrapping things up, example code and documentation
