The previous version of the dwc2 overlay set the RX FIFO size to 256 4-byte words. This is not enough for 1024 bytes of the largest isochronous high speed packet allowed, because it doesn't take into account extra space needed by dwc2. RX FIFO's size is calculated based on the following (in 4byte words): - 13 locations for SETUP packets 5*n + 8 for Slave and Buffer DMA mode where n is number of control endpoints which is 1 on the bcm283x core - 1 location for Global OUT NAK - 2 * 257 locations for status information and the received packet. Typically two spaces are recommended so that when the previous packet is being transferred to AHB, the USB can receive the subsequent packet. - 10 * 1 location for transfer complete status for last packet of each endpoint. The bcm283x core has 5 IN and 5 OUT EPs - 10 * 1 additional location for EPDisable status for each endpoint - 5 * 2 additional locations are recommended for each OUT endpoint Total is 558 locations.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
