Patched EV3 image

The file ev3-fs.patch summarizes the changes done to the original V1.09D image. You can see some text files are edited, the d_usbdev.ko is updated (sources in ../kernel), uf2d added (sources in ../uf2daemon), and a stock nbd.ko module is added.

Additionally, the edimax01.ko is replaced by now much more popular rtl8192cu.ko (also stock).

The init script has a hook for running a shell script from /mnt/ramdisk/. This can be used for testing different modules etc.

The kernel command line has been modified to:

  • disable DMA for the MUSB driver - otherwise the mass storage device is very unstable
  • increase the size of dmesg buffer to 128k
