I just bought a VIM3 Pro board, for start up, inserted the SD that flashed with the image “VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_SD-USB_V20190813”, and went to the “Keys Mode”, the Ubuntu system was boot up successfully, while I met some issues when try to check the hardware info of the board:
khadas@Khadas:/dev$ free -m
total used free shared buff/cache available
Mem: 3370 382 2548 10 439 2942
Swap: 1023 0 1023
installed the lshw, and the result of running it:
description: System memory
physical id: 8
So why it is only about 3GB system memory on the VIM3 Pro board? While the specification (https://www.khadas.com/product-page/vim3) shows 4GB. FYI, after installed dmidecode for further check it: khadas@Khadas:/dev$ dmidecode # dmidecode 3.1 Scanning /dev/mem for entry point. /dev/mem: No such file or directory So is there anything wrong with the Linux Kernel of the VIM3's Ubuntu image?
- The said “5.0 TOPS NPU” maps to what device under /dev?
