Component/s: BSP
Failure observed in LTP - io_control01 test case for ext3 and ext4 filesystem write.
Write counters are not properly shown in the sysfs entries for the above filesystem types.
1. configure and build the project
git clone --branch WRLINUX_10_25_LTS git://lxgit.wrs.com/wrlinux-x
./wrlinux-x/setup.sh --machines bcm-2xxx-rpi4 --distro wrlinux --dl-layers --accept-eula=yes
source environment-setup-x86_64-wrlinuxsdk-linux && source oe-init-build-env build
bitbake-layers add-layer /buildarea2/rpi4_LTS25_LTP_POSIX/LTS25/wr-testing/kts-dev
echo 'require templates/feature/ltp/template.conf' >>conf/local.conf
echo 'BBMASK += "wrlinux/recipes-extended/windriver-ltp/ltp_%.bbappend"' >> conf/local.conf
Add to conf/local.conf:
IMAGE_FSTYPES:remove = "live hddimg iso"
IMAGE_FSTYPES += "tar.bz2"
bitbake wrlinux-image-std
2. Boot up the targets (bcm-2xxx-rpi4) with kernel and rootfs image
3.root@bcm-2xxx-rpi4:/# cd ./opt/wr-test
./main_test.py -x controllers:io_control01
