Introduction ---------------- - -The Xilinx ML300 board is based on the Virtex-II Pro FPGA with -integrated AMCC PowerPC 405 core. The board is normally booted from -System ACE CF. U-Boot is then run out of main memory. - -An FPGA is a configurable and thus very flexible device. To -accommodate for this flexibility this port of U-Boot includes the -required means to regenerate the drivers and configuration files if -you decide to change the hardware design. The required steps are -described below. - - -1. Requirements ---------------- - -To compile and run U-Boot on the Xilinx ML300 platform you need the -following items. - -- A Xilinx ML300 platform (see http://www.xilinx.com/ml300) -- EDK and ISE development tools (shipping with ML300) -- Parallel4 cable (shipping with ML300) -- The EDK reference design for ML300. You can get this as design #6 from - http://www.xilinx.com/ise/embedded/edk_examples.htm -- A BOOTP/TFTP server - - -2. Quick Start --------------- - -To compile and run U-Boot on ML300 follow the steps below. Make sure -to consult the documentation for U-Boot, EDK, and the EDK reference -design for ML300 if you have any questions. - -1. Implement the EDK reference design for ML300. You can use any of - the project files, for example from a xygwin shell: - $ xps -nw system_linux.xmp - XPS% run init_bram -2. Configure and compile U-Boot. Change into the root directory of - U-Boot and run: - $ export CROSS_COMPILE=powerpc-eabi- - $ make ml300_config - $ make -3. Set up the ML300, connect the Parallel4 and the serial cable. Start - a terminal on your host computer and set the communication - parameters to 9600,8N1,no handshake. -4. Set up the BOOTP/TFTP server on your host machine. U-Boot is - preconfigured to use a fixed HW MAC address of 00:0A:35:00:22:01. -5. Download the bitstream to the ML300. -6. Use XMD to download and run U-Boot on the ML300: - $ xmd - XMD% ppcconnect - XMD% dow u-boot - XMD% run - -You can now make an ACE file out of bitstream and U-Boot: - $ xmd genace.tcl -jprog -board ml300 -hw \ - implementation/download.bit -elf u-boot -ace top.ace - -Put the ACE file onto the MicroDrive, for example into xilinx/myace, -and reboot ML300. - - -3. Generating a Custom BSP for U-Boot -------------------------------------- - -If you decide to change the EDK reference design for ML300 or if you -build a new design from scratch either with the Base System Builder in -XPS or all by hand you most likely will change the base addresses for -the Uart and the Ethernet peripheral. If you do so you will have two -options: - -1. Edit boards/xilinx/ml300/xparameters.h to reflect the changes you - made to your hardware. -2. Use the MLD technology provided by Xilinx Platform Studio to make - the changes automatically. To do so go to the root directory of the - EDK reference design for ML300. Copy the Linux project file and the - Linux software configuration file: - $ cp system_linux.xmp system_uboot.xmp - $ cp system_linux.mss system_uboot.mss - - Edit system_uboot.xmp and and have it point to system_uboot.mss for - the software configuration. - - Then, copy the sw_services directory in - boards/xilinx/ml300/sw_services to the root directory of the EDK - reference design for ML300. - $ cp -R <uboot dir>/boards/xilinx/ml300/sw_services <edk dir> - - Modify system_uboot.mss. Look for the Linux library definition - and change it to generate a BSP for U-Boot. An example, might look - like this: - - BEGIN LIBRARY - PARAMETER LIBRARY_NAME = uboot - PARAMETER LIBRARY_VER = 1.00.a - PARAMETER CONNECTED_PERIPHS = (opb_uart16550_0,opb_ethernet_0) - PARAMETER TARGET_DIR = <uboot dir> - END - - Now, you are ready to generate the Xilinx ML300 BSP for U-Boot: - $ xps -nw system_uboot.xmp - XPS% run libs - - If all goes well the new configuration has been copied into the - right places within the U-Boot source tree. Recompile U-Boot and - run it on the ML300. - - -4. ToDo -------- - -- Add support for all other peripherals on ML300. -- Read the MAC address out of the IIC EEPROM. -- Store the bootargs in the IIC EEPROM. - - -5.
