2 SOCFPGA Documentation for U-Boot and SPL
3 ----------------------------------------
5 This README is about U-Boot and SPL support for Altera's ARM Cortex-A9MPCore
6 based SOCFPGA. To know more about the hardware itself, please refer to
13 Here are macro and detailed configuration required to enable DesignWare SDMMC
14 controller support within SOCFPGA
16 #define CONFIG_SYS_MMC_MAX_BLK_COUNT 256
17 -> Using smaller max blk cnt to avoid flooding the limited stack in OCRAM

20 Cyclone 5 / Arria 5 generating the handoff header files for U-Boot SPL
21 ---------------------------------------------------------------------
23 This text is assuming quartus 16.1, but newer versions will probably work just fine too;
24 verified with DE1_SOC_Linux_FB demo project (https://github.com/VCTLabs/DE1_SOC_Linux_FB).
25 Updated/working projects should build using either process below.
27 Note: it *should* work from Quartus 14.0.200 onwards, however, the current vendor demo
28 projects must have the IP cores updated as shown below.
30 Rebuilding your Quartus project
31 -------------------------------
33 Choose one of the follwing methods, either command line or GUI.
35 Using the command line
36 ~~~~~~~~~~~~~~~~~~~~~~
38 First run the embedded command shell, using your path to the Quartus install:
40 $ /path/to/intelFPGA/16.1/embedded/embedded_command_shell.sh
42 Then (if necessary) update the IP cores in the project, generate HDL code, and
45 $ cd path/to/project/dir
46 $ qsys-generate soc_system.qsys --upgrade-ip-cores
47 $ qsys-generate soc_system.qsys --synthesis=[VERILOG|VHDL]
48 $ quartus_sh --flow compile <project name>
50 Convert the resulting .sof file (SRAM object file) to .rbf file (Raw bit file):
52 $ quartus_cpf -c <project_name>.sof soc_system.rbf
55 Generate BSP handoff files
56 ~~~~~~~~~~~~~~~~~~~~~~~~~~
58 You can run the bsp editor GUI below, or run the following command from the
61 $ /path/to/bsb/tools/bsp-create-settings --type spl --bsp-dir build \
62 --preloader-settings-dir hps_isw_handoff/soc_system_hps_0/ \
63 --settings build/settings.bsp
65 You should use the bsp "build" directory above (ie, where the settings.bsp file is)
66 in the following u-boot command to update the board headers. Once these headers
67 are updated for a given project build, u-boot should be configured for the
68 project board (eg, de0-nano-sockit) and then build the normal spl build.
70 Now you can skip the GUI section.
76 1. Navigate to your project directory
78 3. Open Project (Ctrl+J), select <project_name>.qpf
79 4. Run QSys [Tools->QSys]
80 4.1 In the Open dialog, select '<project_name>.qsys'
81 4.2 In the Open System dialog, wait until completion and press 'Close'
82 4.3 In the Qsys window, click on 'Generate HDL...' in bottom right corner
83 4.3.1 In the 'Generation' window, click 'Generate'
84 4.3.2 In the 'Generate' dialog, wait until completion and click 'Close'
85 4.4 In the QSys window, click 'Finish'
86 4.4.1 In the 'Quartus II' pop up window, click 'OK'
87 5. Back in Quartus II main window, do the following
88 5.1 Use Processing -> Start -> Start Analysis & Synthesis (Ctrl+K)
89 5.2 Use Processing -> Start Compilation (Ctrl+L)
91 ... this may take some time, have patience ...
93 6. Start the embedded command shell as shown in the previous section
94 6.1 Change directory to 'software/spl_bsp'
95 6.2 Prepare BSP by launching the BSP editor from ECS
98 6.3.1 Use File -> Open
99 6.3.2 Select 'settings.bsp' file
104 Post handoff generation
105 ~~~~~~~~~~~~~~~~~~~~~~~
107 Now that the handoff files are generated, U-Boot can be used to process
108 the handoff files generated by the bsp-editor. For this, please use the
109 following script from the u-boot source tree:
111 $ ./arch/arm/mach-socfpga/qts-filter.sh \
117 Process QTS-generated files into U-Boot compatible ones.
119 soc_type - Type of SoC, either 'cyclone5' or 'arria5'.
120 input_qts_dir - Directory with compiled Quartus project
121 and containing the Quartus project file (QPF).
122 input_bsp_dir - Directory with generated bsp containing
123 the settings.bsp file.
124 output_dir - Directory to store the U-Boot compatible
127 This will generate (or update) the following 4 files:
134 These files should be copied into "qts" directory in the board directory
135 (see output argument of qts-filter.sh command above).
137 Here is an example for the DE-0 Nano SoC after the above rebuild process:
139 $ ll board/terasic/de0-nano-soc/qts/
141 -rw-r--r-- 1 sarnold sarnold 8826 Mar 21 18:11 iocsr_config.h
142 -rw-r--r-- 1 sarnold sarnold 4398 Mar 21 18:11 pinmux_config.h
143 -rw-r--r-- 1 sarnold sarnold 3190 Mar 21 18:11 pll_config.h
144 -rw-r--r-- 1 sarnold sarnold 9022 Mar 21 18:11 sdram_config.h
146 Note: file sizes will differ slightly depending on the selected board.
148 Now your board is ready for full mainline support including U-Boot SPL.
149 The Preloader will not be needed any more.
151 ----------------------------------------------------------
152 Arria 10 generating the handoff header files for U-Boot SPL
153 ----------------------------------------------------------
155 A header file for inclusion in a devicetree for Arria10 can be generated
156 by the qts-filter-a10.sh script directly from the hps_isw_handoff/hps.xml
157 file generated during the FPGA project compilation. The header contains
158 all PLL, clock, pinmux, and bridge configurations required.
160 Please look at the socfpga_arria10_socdk_sdmmc-u-boot.dtsi for an example
161 that includes use of the generated handoff header.
163 Devicetree header generation
164 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
166 The qts-filter-a10.sh script can process the compile time genetated hps.xml
167 to create the appropriate devicetree header.
170 $ ./arch/arm/mach-socfpga/qts-filter-a10.sh \
174 hps_xml - hps_isw_handoff/hps.xml from Quartus project
175 output_file - Output filename and location for header file
177 The script generates a single header file names <output_file> that should
178 be placed in arch/arm/dts.
