There is something wrong with the BIOS. I have followed all the installation on Wiki. In fact when I finshed the installation I use the aero-get-version.py to check all the state and it was correct like this: BIOS_VERSION = Aero-01.00.16 OS_VERSION = Ubuntu 16.04.4 LTS" AIRMAP_VERSION = unknown FPGA_VERSION = 0xc2 AeroFC firmware version = 1.6.5

But after several times fiy I found the drone got hard to handle. so I checked the firmware by aero-get-version.py today and the result is here:

/sys/firmware/dmi/tables/smbios_entry_point: Permission denied /dev/mem: Permission denied BIOS_VERSION = unknown OS_VERSION = Ubuntu 16.04.4 LTS" AIRMAP_VERSION = unknown FPGA_VERSION = unknown AeroFC firmware version = 1.6.5

I don't know what happened. I try to reflash the BIOS as the link: https://communities.intel.com/thread/124337 but it didn't work.

what are the permission bits on the 2 files it can't access?

zxp771 commented 6 years ago

Hi @lucasdemarchi

Thanks for your reply. I don't know what the permission is. I have never meet these problem before. I just use the command" aero-get-version.py "to check the firmware state.

lucasdemarchi commented 6 years ago

ls -l on these files

zxp771 commented 6 years ago

Hi @lucasdemarchi

Thanks for your help. I just figure out. I should use sudo before the " aero-get-version.py " I'll close this problem.
