Iam currently running benchmarks on the MXA device using the mx\_bench command with **1,000 frames of random data**.

This setup was working previously, however, at the moment **mx\_bench is no longer running successfully** , and **any command related to benchmarking fails** with the following errors:

(mx) memryx@memryxPC:~/Downloads$ mx\_bench -v -d pr.dfp -f 1000

Hi, that looks like the M.2’s firmware needs an [update](https://developer.memryx.com/tutorials/how_to/update_firmware.html). Can you please try:

```auto
# unload kernel module (less chance of issues)
sudo rmmod memx_cascade_plus_pcie

# flash firmware
sudo mxfw_pcie_update_flash -f /lib/firmware/cascade_4chips_flash.bin

```

And then reboot the system?
