Hi everyone, I have an MX3 M.2 accelerator module (purchased a month plug ago from Mouser). It was working normally until I tried to upgrade the MemryX SDK. Below is the log. The accelerator no longer appear under lspci. I tried to slot it in another machine, still not detecting. Before this it ran great, I even ran a face recognition with nine 3k/4k streams and got 20-30FPS per stream. Now when I ran even one stream (using onnx model and not dfp) it barely reach 8FPS. Anyone has any idea how to make it work again? memx\_cascade\_plus\_pcie.ko.zst: - Uninstallation - Deleting from: /lib/modules/6.14.0-35-generic/updates/dkms/ - Original module - No original module was found for this module on this kernel. - Use the dkms install command to reinstall any previous module version. depmod… Deleting module memx-drivers-2.0.5 completely from the DKMS tree.

Hello @ronne991 , From the log you shared, it appears that the **firmware upgrade** and the **`rmmod` step** both failed during the update process. Could you please follow the steps below and let us know if the issue still persists? 1. Purge all MemryX drivers and reinstall the latest version: [Install Runtime (Linux) — MemryX Developer Hub](https://developer.memryx.com/get_started/install_runtime.html) 2. Try updating the firmware independently from the SDK upgrade:: [Update Firmware — MemryX Developer Hub](https://developer.memryx.com/tutorials/how_to/update_firmware.html) Also, could you please clarify the following statement? > “Now when I ran even one stream (using ONNX model and not DFP) it barely reaches 8 FPS.” Are you referring to running the model directly through ONNX Runtime without compiling it to a DFP? Any additional details on how you’re running the inference would help us diagnose the performance issue. ---

Hi @sureshvairamuthu, I followed steps 1 and 2. Step 2 failed because the M.2 unit isn’t being detected. ��\<�pre\>########## Memryx Flash UpdateTool - Directed (V1.6) ############### **Found 0 MemryX Devices.** Memryx PCIe EP not found! \<�/pre\> > [@sureshvairamuthu](#): > > Are you referring to running the model directly through ONNX Runtime without compiling it to a DFP? Any additional details on how you’re running the inference would help us diagnose the performance issue. Yes, that’s what I meant. I didn’t use DFP because the unit isn’t being detected. I used DFP before this issue. Now I am only running the program with onnx ---

Hi everyone, I hit the same issue when running software update on Ubuntu. It hangs on the firmware update process ( I waited for 2 hours and no status update…). Then, the firmware update failed. After that, I tried to re-run the firmware update command on terminal. The process does not finish. I have been waiting for another 30 minutes. Is there any hint to fix this problem? Thanks.

After reboot, the flash image upgrade finished in 1 sec….🙂
