How to add mtd-tests for LS1043ARDB?

tracysmith — Sat, 16 Mar 2019 11:02:09 GMT

Need the recipe/.bb to add user level mtd-tests (included in mtd-utils) for bitbake fsl-image-core. I see a basic mtd-utils .bb under poky/meta/recipes-core/images/core-image-minimal-mtdutils.bb, but this doesn't compile the mtd-tests.

Memory Technology Device (MTD) Subsystem for Linux.

git.infradead.org Git - mtd-utils.git/summary

Memory Technology Device (MTD) Subsystem for Linux.

I need the mtd-tests on the LS1043ardb, how do I add them to the recipes so they are compiled? Please provide the needed recipe that compiles the user level mtd-tests. I need specifically the user level mtd-tests, NOT looking for information on the driver mtd tests. Using the yocto bitbake rather than the LSDK/flex-builder. There is no documentation from NXP on user level mtd-tests, so links will not be helpful here.

Hello Tracy Smith,

Mtd-test utils applications have been configured to be installed with EXTRA_OECONF += "--enable-install-tests" in recipe poky/meta/recipes-devtools/mtd/mtd-utils_git.bb.

Please add "mtd-utils-tests" in the variable RDEPENDS_${PN} in meta-qoriq-demos/recipes-fsl/packagegroups/packagegroup-fsl-mfgtools.bb

RDEPENDS_${PN} = " \
    packagegroup-core-boot \
    bash \
    util-linux \
    dosfstools \
    mtd-utils \
    mtd-utils-ubifs \
    mtd-utils-jffs2 \
    e2fsprogs-mke2fs \
    mtd-utils-tests \
    hdparm \
"

The regenerate rootfs filesystem and boot up the system.

Please check mtd-test related applications in /usr/libexec/mtd-utils/ on the target board.

Have a great day,
TIC

There is no meta-qoriq-demos in SDK 2.0 1703 so this failed to work even after adding.

Hello Tracy Smith,

In SDK 2.0, please edit the recipe meta-freescale/recipes-fsl/packagegroups/packagegroup-fsl-mfgtools.bb to add "mtd-utils-tests".

Thanks,

Yiping

bitbake fsl-image-core builds mtd-utils-tests after adding it in SDK 2.0 1703 meta-freescale/recipes-fsl/packagegroups/packagegroup-fsl-mfgtools.bb?

Hello Tracy Smith,

Please update mtd-utils recipes to higher version, please back up the original sources/poky/meta/recipes-devtools/mtd folder and use the attached mtd recipes folder to replace it.

Thanks,

Yiping

./flash_readtest -v /dev/mtd1
libmtd: error!: ECCGETLAYOUT ioctl request failed
error 95 (Operation not supported)
not NAND flash, assume page size is 512 bytes.
testing page read
Successfully read erase block 0

....
Successfully read erase block 509
Successfully read erase block 510

The message "ECCGETLAYOUT ioctl request failed" indicates the driver is unable to get the ECC NOR memory layout, and requires a NOR ECC no support option be used to remove the message or for layout to be used. Tests ran successfully to completion regardless. How do I provide a No ECC support and how is the layout configured and in what file?
