AM3352: MMC command in Linux SDK

Masashi Ohhashi

Part Number: AM3352

Hi,

my customer would like to know TI_LINUX_SDK include the mmc command in mmc-util. This is the setting when using the eMMC device in pSLC mode. The following is a command example.

./mmc enh_area set -y 0 1933312 /dev/mmcblk1

Ohhashi-san,

'mmc' from the 'mmc-util' project is already part of our current AM335x Linux SDK (v6.0.x, http://software-dl.ti.com/processor-sdk-linux/esd/AM335X/latest/index_FDS.html), see here:

root@am335x-evm:~# mmc enh_area --help
Usage:
        mmc enh_area set <-y|-n|-c> <start KiB> <length KiB> <device>
                Enable the enhanced user area for the <device>.
                Dry-run only unless -y or -c is passed.
                Use -c if more partitioning settings are still to come.
                NOTE!  This is a one-time programmable (unreversible) change.

So please double-check that you are using the latest SDK and let me know if this addresses your concern.

Hi Andreas-san,

Thank you for your reply.

I am using ti-processor-sdk-linux-am335x-evm-06.01.00.08. I checked below file system.

tisdk-rootfs-image-am335x-evm: Included mmc command

arago-base-tisdk-image-am335x-evm: Not included mmc command

arago-tiny-image-am335x-evm: Not included mmc command

I understood which version included mmc command.

I appreciate it.

Best Regards,

M.Ohhashi
