USB on RZ/A1L
We've created a custom board based on the RZ/A1L. It's USB was designed after the RZ/A1H RSK Dev Kit. We are using both Gadget and Host interfaces for the USB, however neither seems to work. The USB...

HW flow control is in the upstream SCIF driver but wasn't in 3.14 version. I back ported it once to talk to a Bluetooth chip, and it did work OK. I'll see if I can figure out what I did with that code...

Hi Chris - Thanks, that solves the mystery. Looking forward to seeing the code.

We will double check the hardware layout. I've tried building them both statically and as modules - the idea was to save some power when USB was not in use by removing the kernel module. Unfortunately,...

Nevermind we just figured it out! The REFIN pin on the RZ must be pulled high instead of low... It works now.Thank you for the support.

Additional correction - The REFRIN pin on the RZ must be pulled low instead of high. It is working now.
