Target Software Installation

Flash memory partitions

Address range	type
0x10000000 - 0x10040000 ( 256KB )	U-Boot
0x10040000 - 0x10060000 ( 128KB )	U-Boot environment variables
0x10060000 - 0x100A0000 ( 256KB )	FPGA bitfile
0x100A0000 - 0x10220000 ( 1.5MB )	Linux kernel image
0x10220000 - end of flash ( ~6MB )	Root filesystem

Linux kernel installation

First check your kernel size is smaller than the armadeus kernel partiiton (ex 1MB) How ?????????????????????????? Load kernel image with u-boot through network:

   BIOS> tftpboot 08000000 pathtoyourhostedbuildrootdir/linux-kernel-2.6.12-arm.bin

or serial line:

   BIOS> loadb 08000000
   Ctrl+Altgr+c to access kermit command line then...
   send pathtoyourhostedbuildrootdir/linux-kernel-2.6.12-arm.bin
   the you can type the c command to reconnect to the terminal

Flash kernel image with:

   BIOS> run flash_kernel

!!! WARNING!! If the new kernel is too large, this operation can destroy data that is stored behind the kernel (e.g. rootfs) !!! Check that Bytes transferred = 1040676 (fe124 hex) value is less than 0xfffff  ????????????????????????,

Linux rootfs installation

Load rootfs image with u-boot through network:

   BIOS> tftpboot 08000000 pathtoyourhostedbuildrootdir/rootfs.arm_nofpu.jffs2

or serial line:

   BIOS> loadb 08000000
   Ctrl+Altgr+\+c to access kermit command line then...
   send pathtoyourhostedbuildrootdir/rootfs.arm_nofpu.jffs2

the you can type the c command to reconnect to the terminal

Flash rootfs image with:

   BIOS> run flash_rootfs

Now you should be ready to test linux:

   BIOS> boot

FPGA firmware installation

The FPGA firmwares are in the armadeus/software/firmware tree You can make some trials with the armadeus/software/firmware/ps2/ps2_top.bin file !!! check your file size is smaller than the firmware partition size (AKA 256KB)

Load FPGA firmware image file with u-boot through network:

   BIOS> tftpboot 08000000 pathtoyourhostedfirmwaredir/fpgafirmware.bin

or serial line:

   BIOS> loadb 08000000
   Ctrl+Altgr+\+c to access kermit command line then...
   C-Kermit> send pathtoyourhostedfirmwaredir/fpgafirmware.bin

then you can type the c command to reconnect to the terminal

Flash firmware image with:

   BIOS> run flash_firmware

Test your new FPGA firmware:

   BIOS> fpga load 0 ${firmware_addr} ${firmware_len}

When your are satisfied with your firmware you can make it autoloaded at power up:

   BIOS> setenv firmware_autoload 1
   BIOS> saveenv
