Rock/bootloader

2014-01-08T13:03:55Z

Wheelcomplex: /* Reverse engineering */

Currently all rk3188 based devices including radxa rock uses the same bootloader from Rockchip. Rockchip don't provide the source code of the bootloader. The bootloader's main task is:

* Load and boot the kernel.img/boot.img or recovery.img from correspoding partition
* Communicate with the host PC to download the image/firmware for [[rock/flash the image | upgrading]]

==Download==
The bootloader of radxa rock can be found at this address
http://dl.radxa.com/rock/images/loader/

==Reverse engineering ==
The analysis of the bootloader is done by sarg. Ping sarg in #linux-rockchip if you are interested. You can find the details here:

== Status ==

Ganbold, a FreeBSD developer, now get FreeBSD booting on rockchip platform. Ganbold told us only basic stuffs, gpio, dwc usb host mode are working. But this is just a start :) If you are interested, ping ganbold at #radxa irc channel on freenode for more details.

== How to boot FreeBSD ==

The instructions are at FreeBSD ARM wiki

https://wiki.freebsd.org/FreeBSD/arm/Radxa%20Rock

Ubuntu 13.10 amd64 rkflashtool build note:

1. install libusb.h by sudo apt-get -y install libusb-1.0-0-dev

2. Turn off the board. Then while pushing Recover button plug usb cable(connected to otg port) to PC and release Recover button.
if rk3188 is no in recover mode you will got "rkflashtool: fatal: cannot open device" when running ./rkflashtool p > param.txt

3. Use follow Makefile:
<PRE>
#
all: rkflashtool

rkflashtool: rkflashtool.c
gcc -o rkflashtool rkflashtool.c -I/usr/include/libusb-1.0/ -lusb-1.0 -O2 -W -Wall

clean:
rm -f rkflashtool

param:
sudo ./rkflashtool r 0x0000 0x2000 > /tmp/parm

#
</PRE>

Ubuntu 13.10 amd64 rkflashtool build note:

1. install libusb.h by sudo apt-get -y install libusb-1.0-0-dev

2. use dmesg or lsusb to check radxa rock is connect ok:

dmesg:
<PRE>

we got device ID 0x0006, and modify rkflashtool.c line 49 from #define PID_RK3188 0x310b to #define PID_RK3188 0x0006

3. Use follow Makefile:
<PRE>
#

Rock/Serial debug tools Setting

2014-01-07T03:34:15Z

Wheelcomplex: /* Linux */

__TOC__

This page describe how to set up and debug the radxa rock board via serial console.

===Windows===
Here we use putty as an example to show us how to set the serial debug tools.

Double click the Putty.exe, you will see the interface like:

[[File:serial_debug_0.png]]

Select the Serial, Fill the Serial line with the right serial port,and the Speed with 115200

[[File:serial_debug_2.png]]

You can get the serial port here:

[[File:serial_debug_1.png]]

Finish setting , Click Open the putty will work

[[File:serial_debug_3.png]]

===Linux===
Here we still use putty as an example.
when start putty firstly you will see this interface:

[[File:serial_debug_linux_0.png]]

Select the Serial, Fill the Serial line with the right serial port,and the Speed with 115200

[[File:serial_debug_linux_1.png]]

How to get the serial port .First cat /proc/tty/drivers, to make sure is there driver support(radxa board is connected with pc via USB so the device name should be usbserial)

[[File:serial_debug_linux_2.png]]

Here we find the line

usbserial /dev/ttyUSB 188 0-253 serial

which tell us the driver is ok, then cd /dev/ to confirm whether is there device named ttyUSB* . you can unplug and then plug the usb to get the right device.

[[File:serial_debug_linux_3.png]]

Finish setting, Click Open the putty will work!

Note:

1、Under Ubuntu If you got the following error – “'''Unable to open connection to: Unable to open serial port'''“. To fix it, add the current user to the “dialout” user group , logout and login to take effect, detail:
