With R-Car Gen3, CRC error occue at the following TAPs. H3, M3W 1.3, M3N... TAP=2,3,6,7 M3W 3.0 ... TAP=1,3,5,7 (Note: for 4tap SoCs, the numbers get divided by 2) Do not use these TAPs in HS400, and also don't use auto correction but manual correction. We check for bad taps in two places: 1) After tuning HS400: Then, we select a neighbouring TAP. One of them must be good, because there are never three bad taps in a row. Retuning won't help because we just finished tuning. 2) After a manual correction request: Here, we can't switch to the requested TAP. But we can retune (if the HS200 tuning was good) because the environment might have changed since the last tuning. If not, we stay on the same TAP.

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.
