eMMC throughput writing to QNX partition time sh -c "dd if=/dev/zero of=/dev/hd0.qnx6.ifs_qnxhyp_b" bs=4096 count=12700 && sync We can also use system OR data partition to write as they are of more size. Other partitions are of ~10 MBs we can check and verify the same with less data transfer accordingly. Check size availability using df -h command eMMC throughput reading from QNX partition time sh -c "dd of=/dev/null if=/dev/hd0.qnx6.ifs_qnxhyp_b" bs=4096 count=12700 && sync eMMC throughput writing to Android partition time sh -c "dd if=/dev/zero of=/dev/block/vda4" bs=4096 count=12700 && sync eMMC throughput reading from Android partition time sh -c "dd of=/dev/null if=/dev/block/vda4" bs=4096 count=12700 && sync Verify QNX eMMC partitions are not available to Android From Android console :- time sh -c "dd if=/dev/zero of="TBD" bs=512000 count=1024 && sync" From QNX Consol...
