Technical Support

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. Can you please try:

# 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?
