FriendlyARM NanoPi R5C: Probably errorneous too low storage size restriction.

Ahoj,

I want to use the OpenWrt firmware selector to build a customised snapshot image for FriendlyARM NanoPi R5C.

This device can boot from microSD or from internal flash storage. Internal storage is 32 GiB, microSD can be even larger.

When I try to build with the following pre-selected packages:

• STDOUT: stdout.log.
  It says:

  [...]
  Creating filesystem with parameters:
      Size: 109051904
  [...]
  

  which seems to be ~1 GiB, smaller than 32 GiB.

  (I came to the conclusion "~1 GiB", since when I request a build just with luci specified as package, I end up with image files that, after gunzip, are ca. 168 MiB in size and the number in STDOUT reads Size: 16777216, which gives a factor of ca. 100 000. Applying this to Size: 109051904 gives ~1 GiB.)

Regards!

Start with the OpenWrt firmware selector request for the FriendlyARM NanoPi R5C and inspect stdout.log, especially the reported 109051904-byte filesystem size and ext4 allocation failure. Trace where the device storage limit is selected and determine what needs to change so a valid customised image can be built for the device.
