It was working perfectly before, but suddenly it stopped working. So flashed suite again. Please help ## Reply by Achyut Sapariya · 2024-12-20 08:53:05 UTC @yashas-katte Same Problem ## Reply by Achyut Sapariya · 2024-12-20 08:54:07 UTC (in reply to Achyut Sapariya) @Achyut-Sapariya @Moderator Please help on this ## Reply by tom (ModalAI staff) · 2024-12-20 17:11:55 UTC (in reply to Achyut Sapariya) @Achyut-Sapariya Can you try updating to the latest SDK (1.3.5) and give it a go? ## Reply by Achyut Sapariya · 2024-12-21 03:25:48 UTC (in reply to tom) @tom I am running The Latest one 1.3.5. I had tried all possible things mentioned on docs but still not getting imu server running. ## Reply by tom (ModalAI staff) · 2024-12-22 20:42:54 UTC (in reply to Achyut Sapariya) @Achyut-Sapariya You said "VOXL suite version : 0.9.5" so I wasn't sure if that was what you currently had loaded. Did the IMU work at one point and then stop working? Trying to determine whether or not this is a hardware issue. ## Reply by Achyut Sapariya · 2024-12-23 06:37:21 UTC (in reply to tom) @tom Yes Initially IMU was working but suddenly next day it stops working. ## Reply by tom (ModalAI staff) · 2024-12-23 18:43:59 UTC (in reply to Achyut Sapariya) @Achyut-Sapariya When flashing the board did you go through SKU setup and allow `voxl-configure-mpa` to run? Can you post the output of `voxl-version` and `voxl-inspect-sku`? ## Reply by Achyut Sapariya · 2024-12-24 04:49:05 UTC (in reply to tom) @tom I didn't aware about SKU setup but when I flashed i had run ``` voxl-configure-mpa ``` output of ```voxl-version``` ``` voxl2:/$ voxl-version -------------------------------------------------------------------------------- system-image: 1.7.10-M0054-14.1a-perf kernel: #1 SMP PREEMPT Fri Sep 27 21:18:59 UTC 2024 4.19.125 -------------------------------------------------------------------------------- hw platform: M0054 mach.var: 1.0.0 -------------------------------------------------------------------------------- voxl-suite: 1.3.5 -------------------------------------------------------------------------------- Packages: Repo: http://voxl-packages.modalai.com/ ./dists/qrb5165/sdk-1.3/binary-arm64/ Last Updated: 2024-12-20 06:50:35 List: kernel-module-voxl-fsync-mod-4.19.125 1.0-r0 kernel-module-voxl-gpio-mod-4.19.125 1.0-r0 kernel-module-voxl-platform-mod-4.19.125 1.0-r0 libfc-sensor 1.0.7 libmodal-cv 0.5.11 libmodal-exposure 0.1.1 libmodal-journal 0.2.2 libmodal-json 0.4.3 libmodal-pipe 2.10.2 libqrb5165-io 0.4.6 libvoxl-cci-direct 0.2.3 libvoxl-cutils 0.1.1 modalai-slpi 1.1.19 mv-voxl 0.1-r0 qrb5165-bind 0.1-r0 qrb5165-dfs-server 0.2.0 qrb5165-imu-server 1.0.1 qrb5165-rangefinder-server 0.1.3 qrb5165-slpi-test-sig 01-r0 qrb5165-system-tweaks 0.3.0 qrb5165-tflite 2.8.0-2 voxl-bind-spektrum 0.1.1 voxl-camera-calibration 0.5.7 voxl-camera-server 2.0.1 voxl-ceres-solver 2:1.14.0-10 voxl-configurator 0.8.5 voxl-cpu-monitor 0.4.8 voxl-docker-support 1.3.1 voxl-elrs 0.2.2 voxl-esc 1.4.7 voxl-feature-tracker 0.4.1 voxl-flow-server 0.3.6 voxl-fsync-mod 1.0-r0 voxl-gphoto2-server 0.0.10 voxl-gpio-mod 1.0-r0 voxl-jpeg-turbo 2.1.3-5 voxl-lepton-server 1.2.3 voxl-lepton-tracker 0.0.2 voxl-libgphoto2 0.0.4 voxl-libuvc 1.0.7 voxl-logger 0.4.7 voxl-mavcam-manager 0.5.7 voxl-mavlink 0.1.1 voxl-mavlink-server 1.4.2 voxl-modem 1.1.3 voxl-mongoose 7.7.0-1 voxl-mpa-to-ros 0.3.9 voxl-mpa-tools 1.2.3 voxl-neopixel-manager 0.0.3 voxl-open-vins 0.4.14 voxl-open-vins-server 0.2.75 voxl-opencv 4.5.5-2 voxl-osd 0.0.1 voxl-platform-mod 1.0-r0 voxl-portal 0.7.0 voxl-px4 1.14.0-2.0.84 voxl-px4-imu-server 0.1.2 voxl-px4-params 0.5.3 voxl-qvio-server 1.0.4 voxl-remote-id 0.0.9 voxl-reset-slpi 0.0.1 voxl-state-estimator 0.0.2 voxl-streamer 0.7.4 voxl-suite 1.3.5 voxl-tag-detector 0.0.4 voxl-tflite-server 0.3.4 voxl-utils 1.4.3 voxl-uvc-server 0.1.7 voxl-vision-hub 1.8.9 voxl-vtx 1.1.0 voxl2-io 0.0.3 voxl2-system-image 1.7.10-r0 voxl2-wlan 1.0-r0 -------------------------------------------------------------------------------- ``` output of ```voxl-inspect-sku``` ``` voxl2:/$ voxl-inspect-sku family code: MRB-D0006 (sentinel) compute board: 4 (voxl2) hw version: 1 cam config: 11 modem config: 4 (LTE v2, 7610 NA (M0030)) tx config: 7 (elrs_beta_fpv) extras config: 0 (none) SKU: MRB-D0006-4-V1-C11-T7-M4-X0 ``` ## Reply by tom (ModalAI staff) · 2024-12-26 19:10:59 UTC (in reply to Achyut Sapariya) @Achyut-Sapariya That all looks normal, I'd recommend submitting an RMA and our team can diagnose the issue: https://www.modalai.com/pages/rma
