Configuring Minized Petalinux Wi-Fi with custom PL

caheike1

I programmed my logic into the PL on a minized and using the petalinux tools configured a 4.9 version of petalinux for it.  Linux and the PL work well, except networking.  The wifi.sh script that came with the minized does a ‘modprobe bcmdhd’.   This appears to be a custom kernel module that contains the Wi-Fi drivers.  I am unable to find the source for the module so that I can build it myself  or to configure the kernel to support this Wi-Fi chip without the module.  Also,  I would also like to get a copy of the configuration files for the petalinux kernel and rootfs that matches the image.ub that comes with the board so that I can create my own image.ub using my version of the PL.   Has anyone successfully built a petalinux image.ub and gotten Wi-Fi to work?    Does anyone know where to get the stock petalinux configuration files?

    Thanks to Stefan and Josh I have managed to get this going without having to use the JTAG.

     

    So as Stefan says as long as you have WIFI going on the board you can do it all over WIFI (thanks very much Stefan)

     

    If you are changing the u-boot or bitstream you need a boot.bin file, you can get it like this:

     

    petalinux-package --boot --fsbl 'images/linux/zynq_fsbl.elf' --fpga 'images/linux/minized_petalinux_wrapper.bit' --u-boot

     

     

    You need to copy these files to the minized over wifi (mine is at 192.168.1.105):

     

    scp images/linux/BOOT.BIN root@192.168.1.105:/mnt/emmc/smallboot.bin

    scp images/linux/image.ub  root@192.168.1.105:/mnt/emmc/image.ub

     

     

    Then if you have changed the boot.bin you need to copy it to the QSPI on the minized:

     

    flashcp /mnt/emmc/smallboot.bin /dev/mtd0

     

    Then reboot the minized with fingers crossed.
