To Reproduce
Steps to reproduce the behavior:
1.Prepare the spdk configuration file
cp /KVSSD/application/kvbench/spdk/spdk/etc/spdk/rocksdb.conf.in /tmp/rocksdb.conf
/KVSSD/application/kvbench/spdk/spdk/scripts/gen_nvme.sh >> /tmp/rocksdb.conf
2. Reserve hugepage
cat /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
3. Setup spdk environment
/KVSSD/application/kvbench/spdk/spdk/scripts/setup.sh
4. Create BlobFS on the device
/KVSSD/application/kvbench/spdk/spdk/test/lib/blobfs/mkfs/mkfs <your_conf_file> <device_name>
e.g. ./test/lib/blobfs/mkfs/mkfs /tmp/rocksdb.conf Nvme0n1

Expected behavior
create blobfs correctly.

Blobfs needs block firmware. Your SSD was downloaded the KV firmware. Please firstly download the block firmware to SSD, then try it again.
