How to compile stuff (in my case Wifi module) on the VF2?

Hello Manux,

you have to re compile the linux kernel again, then you can re- complie the ESWIN.
Or do you use my kerenl which is already cross compiled.

  1. git clone GitHub - starfive-tech/linux
  2. cd linux
  3. touch .scmversion
  4. git checkout --track origin/JH7110_VisionFive2_devel
  5. vi Makefile
VERSION = 5
PATCHLEVEL = 15
SUBLEVEL = 0
EXTRAVERSION = -starfive
NAME = Trick or Treat
  1. git pull
  2. sudo apt install flex
  3. sudo apt install bison
  4. sudo apt install bc
  5. make starfive_visionfive2_defconfig
  6. make -j3

Then go to:

  1. cd /home/user/eswin_6600u

make KERNELDIR=/<path to linux from step 1>/linux/ KBUILDDIR=/<path to linux from step 1>/linux/ product=6600u

Makefile:142: "select chip is 6600u."
Makefile:144: "select slave is used CEVA RTOS."
rm -rf *.ko
make -C /home/damian/data/linux/ O=/home/damian/data/linux/ M=/home/damian/data/eswin_6600u modules
