I am getting booting issue while porting linux image(zImage) on my raspberrypi2 board. The infrastructure in doing so are:
Hardware
- Raspberry Pi 2 board
- USB to Serial converter
Software:
- Ubuntu 14.04 LTS on host system
- Buildroot_2015_11_1
For the configuration of buildroot I followed the instructions described in the buildroot link below: https://git.busybox.net/buildroot/tree/board/raspberrypi/readme.txtbuildroot configuration process
After generating the image I flashed my SD card(16 GB) with the generated images and binaries in boot partition and root file system in root partition. (My boot partition is 60 MB (FAT32).
My cmdline.txt
content is
dwc_otg.fiq_fix_enable=1
sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0
console=tty1
root=/dev/mmcblk0p2 rootwait
I even changed it to
dwc_otg.lpm_enable=0
console=ttyAMA0,115200
console=tty1
root=/dev/mmcblk0p2
rootfstype=ext3
elevator=deadline rootwait
in order to make it work but that even did not work (I mean RPI not booting).
In my config.txt
, the kernel assignment was kernel=zImage
(even then RPI not booting) I even changed it to kernel=u-boot.bin
and the problem still exists.
Note: I am using putty or minicom both but unable to see the booting sequence.
I have also tried the way the paper of Mariano Ruiz describes about buildroot configuration but still the problem remains the same.
Please let me know how to proceed in such scenario.
