On this page you will learn how to flash new U-Boot, Linux and rootfs images on your APF module.
Contents
Configure U-Boot
Environment variables
U-Boot can be customized in a flexible way with the use of "environment variables/scripts". The command printenv shows you most of them and their current value:
BIOS> printenv bootcmd=run jffsboot bootdelay=20 baudrate=115200 ethaddr= autoload=no ...
The command setenv is used to change these variables. For example, to set the IP address (don't do it yet):
BIOS> setenv ipaddr 192.168.0.10
The command saveenv is used to save the state of your environment variables in FLASH memory; that way they will be available at next boot:
BIOS> saveenv Saving Environment to Flash... . done Un-Protected 1 sectors Erasing Flash... . done Erased 1 sectors Writing to Flash... done . done Protected 1 sectors
Network configuration
In order to use the U-Boot's network features, you have to set the network environment variables:
BIOS> setenv netmask 255.255.255.0 (this default value should be fine in most situations) BIOS> setenv ipaddr 192.168.0.10 BIOS> setenv serverip 192.168.0.2 (the IP address of your tftp server/PC hosting the files to download) BIOS> setenv rootpath "/tftpboot/apf9328-root" (to boot Linux over NFS)
You can use the dhcp command to configure these variables from your DHCP server. You probably will have to adjust the serverip variable manually.
BIOS> dhcp dm9000 i/o: 0x15c00000, id: 0x90000a46 MAC: 00:0e:32:00:00:01 operating at 100M full duplex mode BOOTP broadcast 1 DHCP client bound to address 192.168.0.10 BIOS> setenv serverip 192.168.0.2 BIOS> saveenv
Do not forget to save your changes in FLASH, to have them available at next power up:
BIOS> saveenv
In case of troubles you can use the following U-Boot script to reset the variables to the "factory"/default settings:
BIOS> run flash_reset_env
Linux kernel installation
XX, in the following chapters, has to be replaced by your board name
- Check that your Armadeus kernel image size is smaller than the U-Boot partition (see Flash Memory Partitions for size allowances):
[armadeus]$ ls -al buildroot/binaries/XX/
- If yes, copy it to your TFTP server directory (here /tftpboot/):
[armadeus]$ cp buildroot/binaries/XX/XX-linux.bin /tftpboot/
- Load kernel image with U-Boot through network:
BIOS> tftpboot ${loadaddr} XX-linux.bin
or with the serial line:
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then:''
(/home/.../) C-Kermit>send /tftpboot/XX-linux.bin
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.

## Total Size = 0x0013d0b0 = 1298608 Bytes
## Start Addr = 0x08000000

 |
Warning: If the loaded kernel image is too large, the following operation can destroy data that are stored after the partition limits (e.g. RootFS) |
Check that transfered size value is less than the ones specified here Flash Memory Partitions
Bytes transferred = 1313216 (1409c0 hex)
- You can test your new kernel image without flashing it with; if so you will have to reload it again after test:
- Please note: The bootm command is not supported on APF51 boards yet; directly flash the kernel with the below commands instead
BIOS> bootm ${loadaddr}
- a U-Boot script exists to ease kernel image loading through Ethernet:
BIOS> run download_kernel
- After kernel image has been downloaded into RAM memory, you can flash it with:
BIOS> run flash_kernel
- To make it easier, you can use automatic scripts that will download the image and flash it in the same go. So next time you will only launch:
BIOS> run update_kernel
- To know what update_kernel script is doing you can display its content:
BIOS> printenv update_kernel
- If you only want to try a new kernel without flashing the kernel image you can launch it directly from RAM:
BIOS> setenv bootargs ${console} ${mtdparts}; run addjffsargs addipargs; bootm
(the kernel image you want to try must have been loaded at ${loadaddr})
rootfs installation
- Check that your Armadeus rootfs image size is smaller than the rootfs partition (see Flash Memory Partitions for size allowances):
[armadeus]$ ls -al buildroot/output/images/ ... [armadeus]$ cp buildroot/output/images/XX-rootfs.ubi /tftpboot/ (apf9328-rootfs.jffs2 on [[APF9328]]
- Load rootfs image with U-Boot through network:
BIOS> tftpboot ${loadaddr} XX-rootfs.ubi (apf9328-rootfs.jffs2 on [[APF9328]]
For large rootfs (bigger than the available RAM on your system) please use this method (not supported on the APF9328):
BIOS> tftpboot ${rootfs_offset} XX-rootfs.ubi nand
or serial line:
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then...''
(/home/.../) C-Kermit>send path_to_your_host_buildroot_dir/XX-rootfs.ubi
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x........
## Start Addr = 0x........
BIOS>
- Flash rootfs image with:
BIOS> run flash_rootfs
- Now you should be ready to test Linux:
BIOS> boot
- To make it easier, you can use U-Boot scripts we defined. So next time you will only launch:
BIOS> run update_rootfs
FPGA firmware test
The FPGA firmwares are all located in the firmware/ directory of your Armadeus view:
[armadeus]$ ls firmware/ apf_pkg BRAMTest bus_led led PS2 PS2_Opencore servo sram_test wishbone_example Xtools
You can make some trials with the firmware/PS2/ps2_top.bin file.
| |
Warning: for the APF9328, Check that your bitfile size is smaller than the firmware partition size (256KB) before trying the following commands or you may corrupt your Linux kernel FLASH partition !!! |
 |
Note: For the APF51 only binary file format work (.bin). Do not use .bit format |
- Load FPGA firmware image file with U-Boot through:
Ethernet:
BIOS> tftpboot ${loadaddr} fpgafirmware.bin
fpgafirmware.bin is of course the name of your bitfile stored in your TFTP shared directory (/tftpboot/)
or serial line:
BIOS> loadb ${loadaddr}
Ctrl+Altgr+\+c to access kermit command line then...
C-Kermit> send path_to_your_tftp/fpgafirmware.bin
then you can type the c command to reconnect to the terminal
- Test your new FPGA firmware's downloading:
BIOS> fpga load 0 ${loadaddr} ${firmware_len}
FPGA firmware installation
- Flash your firmware image with:
BIOS> run flash_firmware
- When you are satisfied with your firmware, you can make it "autoloaded" at power up:
BIOS> setenv firmware_autoload 1 BIOS> saveenv
Update U-Boot
There are two steps to update U-Boot:
Load the new U-Boot code in RAM
You can use the following commands to download U-boot:
- With Ethernet and a TFTP server:
BIOS> tftpboot ${loadaddr} apf9328-u-boot.bin
- With Ethernet and a NFS server:
BIOS> nfs ${loadaddr} host_ip_addr:/nfs_path_to_buildroot/apf9328-u-boot.bin
- With kermit and the serial/RS232 line
BIOS> loadb ${loadaddr}
<CTRL><ALT GR>\
c
send path_to_buildroot/apf9328-u-boot.bin
c<ENTER>
Transfer code from RAM to Flash memory
There is a simple U-Boot command/script to do that:
BIOS> run flash_uboot
Advanced informations can be found at the BootLoader wiki page.
