    @Jae-Park Correct, I’d your team didn’t explicitly purchase it then you’ll have to order it from https://www.modalai.com/collections/voxl-add-ons/products/voxl-usb-expansion-board-with-debug-fastboot-and-emergency-boot

    Hi @modalab , Thanks for the information. So, will you design a compatible landing gear for gimbal? I saw there was a gimbal purchase option on the website but disabled. I also saw the below link of the gimbal: https://docs.modalai.com/voxl-m500-gimbal-user-guide/ I am wondering if the team will make a higher version of landing gear in the upcoming release? I am also interested in the landing gear of the upcoming Flight-RB5. https://docs.modalai.com/Qualcomm-Flight-RB5-datasheet/ It looks like a lower version but more stable, and I am wondering if this landing gear will work for the current m500?

    No, beta flight is not supported. PX4 is fully supported. ArduPilot support has been added by the ArduPilot team, but not fully integrated at ModalAI

    @Eric-Katzfey said in Set static IP on ModalAI M500: @vmassague You can try this: https://www.howtogeek.com/118337/stupid-geek-tricks-change-your-ip-address-from-the-command-line-in-linux/ Is there a way to set the static IP permanently? I saw that in the WiFi guide you recommend reserving the IP in the WiFi router, unfortunately that's not an option for me.

    @shaul-Kutner I'm not sure I understand your question. The Voxl application processor is running Linux which is a virtual memory system so applications have nearly unlimited memory to use. In terms of non-volatile storage you can see the partitions with the Linux df command: / # df -h Filesystem Size Used Avail Use% Mounted on /dev/root 2.8G 1.9G 906M 68% / devtmpfs 1.8G 0 1.8G 0% /dev tmpfs 1.9G 0 1.9G 0% /dev/shm tmpfs 1.9G 8.8M 1.9G 1% /run tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup tmpfs 1.9G 4.0K 1.9G 1% /var/volatile /dev/sda2 2.2M 80K 2.0M 4% /persist /dev/sda3 58M 40K 57M 1% /cache /dev/sde12 12M 4.1M 7.4M 36% /dsp /dev/sde11 95M 33M 63M 35% /firmware /dev/mmcblk0p1 15G 5.6G 8.3G 41% /mnt/sdcard /dev/sda9 15G 138M 14G 1% /data And for RAM you can check out the Linux /proc/meminfo file: MemTotal: 3861320 kB MemFree: 3144828 kB MemAvailable: 3377772 kB Buffers: 18844 kB Cached: 229416 kB SwapCached: 0 kB Active: 246908 kB Inactive: 212448 kB Active(anon): 211300 kB Inactive(anon): 16984 kB Active(file): 35608 kB Inactive(file): 195464 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 211144 kB Mapped: 50512 kB Shmem: 17196 kB Slab: 87524 kB SReclaimable: 31308 kB SUnreclaim: 56216 kB KernelStack: 9744 kB PageTables: 2624 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 1930660 kB Committed_AS: 2012136 kB VmallocTotal: 258998208 kB VmallocUsed: 68020 kB VmallocChunk: 258812108 kB

    Hi @mohammednaveed , I tried clicking on refresh, but nothing happened. Anyways, I already updated the firmware and put sdcard in. So, I will not miss out on the logs again. Thanks.

    Hi @mohammednaveed , It seems I couldn't access the log of the crash anymore, because I didn't put sdcard to save the log. I also updated the firmware after the crash, so the previous logs were wiped out. Anyways, I will share the log next time if I get crash again. Thanks.

    @JoeC Seems like it is an SD card issue. I was able to recreate the problem when using a SanDisk Extreme 32GB card. But when using a SanDisk Ultra 16GB card everything works fine.

    @czarsimon omx has a very limited set of input formats. I would add format NV12 (or NV21) to your caps filter in between videotestsrc and omx.

    I believe you should just be able to clone boost and perform a make install inside the docker. You can then save the state of that docker so you don't need to repeat that step later.

    Thanks! I think there was some confusion about which connector to plug into, but that clarifies it. Also, any reason why the RB5 ships with a different antenna type than the VOXL?

    @RichieRich , I may find an issue with one of the batteries (the blue one in the above pic). I was trying to charge it with 4S 14.8v, 3.3A settings, but the charger tells that the blue one is recognized as only 3S and breaks the charging every time. It's quite weird why the charger tests the battery as a 3S setting. The green one works well, and no CPU error happened after fully charging. So, I think I may have to contact the battery provider to double-check the quality of the blue one. Since the blue one cannot charge at the time, I may not be able to test this error with logs. I will get back if the battery provider could advise me how to charge it.
