Vyasa RK3288
############
This tutorial will show the details of Vyasa RK3288 Linux BSP Guide. Most of the software supported by Vyasa is mainlined already.
You can check `hardware details here `_
Hardware Access
***************
Serial: NULL Modem cable, Serial-to-USB converter
Power: DC-in 12V ~ 24V socket supply
Sometimes junk characters show on serial console so better to plug-in USB OTG cable
.. image:: /images/vyasa.jpg
Prebuilt Image
**************
Insert the SD card on to host and write the image.
::
$ git clone https://github.com/openedev/rootfs-rk32
$ cd rootfs-rk32/boot
$ xzcat sdcard-vyasa.img.xz | dd of=/dev/mmcblk0
$ sync
$ umount /dev/mmcblk0*
Turn-on the board
BSP Building
************
Manual Build
============
Image building need host to ready with all necessary tools ready, refer `here `_
U-Boot
------
::
$ git clone git://git.denx.de/u-boot.git
$ cd u-boot
$ make vyasa-rk3288_defconfig
$ make
Linux
-----
::
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ cd linux-next
$ make mrproper
$ ARCH=arm make multi_v7_defconfig
$ ARCH=arm make menuconfig
[select CONFIG_DWMAC_ROCKCHIP=m]
$ ARCH=arm make -j 4 LOADADDR=0x02000000 uImage dtbs
$ ARCH=arm make modules -j 4
#modules would installed in lib/ directory of kernel source
$ ARCH=arm make modules_install -j 4 INSTALL_MOD_PATH=./
#for linux-next kernel repo
$ find . -name *`cat localversion-next`
Rootfs
------
Buildroot
=========
It's easy to build entire system using buildroot and mainline supported Vyasa board already. See read this `readme.txt `_ for more info.
::
$ git clone git://git.busybox.net/buildroot
$ cd buildroot
$ make amarula_vyasa_rk3288_defconfig && make
Prepare your SDCard:
Buildroot generates a ready-to-use SD card image that you can flash directly to the card. The image will be in output/images/sdcard.img. You can write this image directly to an SD card device (i.e. /dev/xxx)
::
$ sudo dd if=output/images/sdcard.img of=/dev/xxx
$ sudo sync
Finally, you can insert the SD card to the Vyasa RK3288 board, close J4 and boot it.

Jtag debugging needs a jtag-breakout program to be flashed to eMMC while connecting
jtag probe through sd-card pins. This can be done by using a sd-card sniffer(i.e. Sparkfun
microSD Sniffer). Follow this repository to make it work:
