The rk3568 CAN-FD errata sheet as of Tue 07 Nov 2023 11:25:31 +08:00 says: | A dominant bit at the third bit of the intermission may cause a | transmission error. | | When sampling the third bit of the intermission as a dominant bit, if | tx_req is configured to transmit extended frames at this time, the | extended frame may be sent to the bus in the format of a standard | frame. The extended frame will be sent as a standard frame and will not | result in error frames Turn on "Interframe Spaceing RX Mode" only during TX to work around erratum 12, according to rock-chip: | Spaceing RX Mode = 1, the third Bit between frames cannot receive | and send, and the fourth Bit begins to receive and send. | | Spaceing RX Mode = 0, allowing the third Bit between frames to | receive and send.

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 reStructuredText 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.
