Dear All,
We have T2080RDB development kit trying to run classifier_demo.
We are following SDK2.0 document ( Running classifier_demo) chapter.
Enabled offloading driver in the kernel and using t2080rdb-usdpaa.dpa dtb but /dev/dpa_classifier /dev/dpa_stats do not create in the linux.
We set setenv othbootargs “fsl_fm_max_frm=9600" in the boot prompt.
and we are exporting export DEF_CFG_PATH=/usr/etc/classifier_demo_config-b4860.xml export DEF_PCD_PATH=/usr/etc/classifier_demo_policy.xml export DEF_PDL_PATH=/etc/fmc/config/hxs_pdl_v3.xml
Then /dev/dpa_classifier /dev/dpa_stats should create but do not. Please let me know where is the mistake.
Thanks, Vidya
