There is a command to read the extcsd and some commands to configure particular features, but no generic write extcsd command. Such a command may be useful for not-yet-supported features and manufacturer-specific registers.

MMC tools (mmc-utils) ===================== mmc-utils is a tool for configuring MMC storage devices from userspace. Contribution guidelines ----------------------- The project works using a mailing list patch submission process, similar to the process used for the Linux kernel itself. One can document themselves by reading how to submit a patch in the official Linux kernel documentation: https://www.kernel.org/doc/html/latest/process/submitting-patches.html Not all sections apply but it should be a good way to get started. A patch should be sent as a mail (not as an attachement, see documentation above) to the linux-mmc@vger.kernel.org mailing list with maintainers as Cc recipients.
