u-boot-1.1.5-ronetix is used for basic initialization of the PM9261/PM9263 boards
and for loading and starting an Operating system or an user application.
The loading can be done via the various FLASH devices or the Ethernet.

u-boot supports the following devices on the PM9261/PM9263 board:

- NOR Flash
- Dataflash
- NAND flash
- Ethernet
- LCD
- DS2401 - serial number chip for generating an unique MAC address

How to build and install U-BOOT?

1. Download and install the GNU toolchain:

	wget http://download.ronetix.info/toolchains/arm/ronetix-gnutools-arm-elf-4.1.1-linux.tar.bz2
	su -
	cd /
	tar xvfj ronetix-gnutools-arm-elf-4.1.1-linux.tar.bz2
	exit

	Setup the path:

	export PATH=/usr/cross/arm-elf/bin:$PATH

	This toolchain includes:
		binutils-2.17.50.0.6
		gcc-4.1.1
		newlib-1.14.0
		insight-6.5



2. Download and install the U-BOOT

	wget http://download.ronetix.info/sk-eb926x/linux/bootloader/u-boot-1.1.5/u-boot-1.1.5-ronetix-08-07-23.tar.bz2 
	
	tar xvfj u-boot-1.1.5-ronetix-08-07-23.tar.bz2
	cd u-boot-1.1.5-ronetix


3. Configuration

The u-boot configuration files are:
    include/configs/pm9261.h
    include/configs/pm9263.h
   	
The definitions are explained in the README file.

Set the lines for the network interface:
#define CONFIG_ETHADDR		DE:AD:BE:EF:01:01
#define CONFIG_IPADDR		10.120.81.138
#define CONFIG_NETMASK		255.255.255.0
#define CONFIG_GATEWAYIP	10.120.81.1
#define CONFIG_SERVERIP		10.120.81.129
#define CONFIG_HOSTNAME		PM9261

These parameters can be modified later and set to a environment variables.

If you do not want LCD support, comment out:

#define  CONFIG_LCD			1


If you have a 16-bit NAND Flash define this:

#define CONFIG_MTD_NAND_AT91_BUSWIDTH_16


To determine what kind of NAND Flash chip do you have look at bottom 
side of the CPU module for:
   U5 - MT29F2G16  - 16-bit NAND Flash
   U9 - MT29F2G08  -  8-bit NAND Flash



4. Building
	make pm9261_config
	or
	make pm9263_config

	make

5. Installation

The file u-boot.bin must be programmed in the FLASH at address 0x10000000 (after remap).
The environment of u-boot is at address 0x10030000.
If you use PEEDI the command is:

peedi> flash erase
peedi> flash program u-boot.bin bin 0x10000000

Next restart the board or start it from PEEDI CLI:

peedi> go 0x10000000
