donno hat is wrong please assist !!

There's no need to use sudo to compile the kernel.

I suggest you to start with the clean kernel source code, and run these commands in the new kernel directory:

export ARCH=arm
export CROSS_COMPILE=$HOME/prebuilts/bin/arm-eabi-
make firefly-rk3288-linux_defconfig
make -j8 firefly-rk3288.img

The kernel needs to locate "${CROSS_COMPILE}gcc" to compile source codes.

Thank you . At least I am back on the right track. need to carry on with the rest of the list

Hello

I am now stuck at the following step: Modify Parameter File

Modify Parameter File

The root file system can reside on different partitions in different storage devices (eMMC, TF card or USB disk, etc). It must be specified in the kernel's command line. There is a CMDLINE in the paramter file:

<<my board is running on the eMMC only I have no usb nor tf card>>>>> please provide correct command

CMDLINE:console=ttyFIQ0 ... mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),...,-@0x00394000(user)

Add one of below according to your need: (# and contents after are comments, no need to enter):

root=/dev/block/mtd/by-name/linuxroot        # flash partition named "linuxroot"
root=/dev/mmcblk0p1          # First partition of TF card
root=/dev/sda1               # First partition of USB disk
root=LABEL=linuxroot         # Partition whose label is "linuxroot"


Not sure what to do here and what parameters to use in the command line.
The 2 last steps are vague for me if you can help.
As for flashing the board that has been done many time so there should be no issue.

busybee

I suggest that you extract the parameter file from your working board.

First install rkflashkit following this link:
  http://wiki.t-firefly.com/index. ... image/en#rkflashkit

Then:
   sudo rkflashkit backup @parameter parameter.txt

The info in parameter partition is saved as parameter.txt.

Edit parameter.txt as you pleased.  Generally speaking, you only need
to modify the partition layout prefixed with 'mtdparts='.

To flash back the parameter.txt to the board, run:
  sudo rkflashkit flash @parameter parameter.txt

In my case I assume that I only need to do the kernel image. I tried with androidtool to download image for kernel
The default Kernel address in Androidtool is 0x0000E000 and this address does not exist in my parameters file.

Thank you for your continuous help and assistance.

busybee

It seems that androidtool did not read the address from parameter info on board. You need to manully edit that address to match your parameter file.

Or you can use rkflashkit. It has both gui and command line, and it'll fetch the parition first from your board.

Simply run:
   sudo rkflashkit

to launch gui, or:
   sudo rkflashkit flash @boot /PATH/TO/boot.img
   sudo rkflashkit flash @resource /PATH/TO/resource.img

to update the boot.img(kernel+initramfs) and resource.img(logo+kernel dtb).

Hello Busybee,
I succeeded to flash it to the board however I still have kernel 3.10.

I also noticed the following after running the command :
make INSTALL_MOD_PATH=./modules_install modules_install

INSTALL drivers/gpu/arm/midgard/mali_kbase.ko
  INSTALL drivers/media/usb/gspca/gspca_main.ko
  DEPMOD  3.10.0

Kernel 3.10.0 is of no use to me. Could you please investigate and let me know?
