commit14f89e0881upstream. Due to the use of sizeof(), command size set for the spi transfer was wrong. Driver was sending and receiving always 1 byte less and especially on write, it was hanging. echo -n -e "\\x1\\x2\\x3\\x4" > /dev/mtd1 And read part too now works as expected. hexdump -C -n16 /dev/mtd1 00000000 01 02 03 04 ab f3 ad c2 ab e3 f4 36 dd 38 04 15 00000010 Fixes:4379075a87("mtd: mchp23k256: Add support for mchp23lcv1024") Signed-off-by: Angelo Dureghello <angelo.dureghello@timesys.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
