Altera SOCFPGA Arria10 FPGA Manager
|
|
|
|
Required properties:
|
|
- compatible : should contain "altr,socfpga-a10-fpga-mgr"
|
|
- reg : base address and size for memory mapped io.
|
|
- The first index is for FPGA manager register access.
|
|
- The second index is for writing FPGA configuration data.
|
|
- resets : Phandle and reset specifier for the device's reset.
|
|
- clocks : Clocks used by the device.
|
|
- altr,bitstream : Fit image file name for both FPGA peripheral bitstream,
|
|
FPGA core bitstream and full bitstream.
|
|
|
|
Full bitstream, consist of peripheral bitstream and core
|
|
bitstream.
|
|
|
|
FPGA peripheral bitstream is used to initialize FPGA IOs,
|
|
PLL, IO48 and DDR. This bitstream is required to get DDR up
|
|
running.
|
|
|
|
FPGA core bitstream contains FPGA design which is used to
|
|
program FPGA CRAM and ERAM.
|
|
|
|
Example: Bundles both peripheral bitstream and core bitstream into FIT image
|
|
called fit_spl_fpga.itb. This FIT image can be created through running
|
|
this command: tools/mkimage
|
|
-E -p 400
|
|
-f board/altera/arria10-socdk/fit_spl_fpga.its
|
|
fit_spl_fpga.itb
|
|
|
|
For details of describing structure and contents of the FIT image,
|
|
please refer board/altera/arria10-socdk/fit_spl_fpga.its
|
|
|
|
- Examples for booting with full release or booting with early IO release, then
|
|
follow by entering early user mode:
|
|
|
|
fpga_mgr: fpga-mgr@ffd03000 {
|
|
compatible = "altr,socfpga-a10-fpga-mgr";
|
|
reg = <0xffd03000 0x100
|
|
0xffcfe400 0x20>;
|
|
clocks = <&l4_mp_clk>;
|
|
resets = <&rst FPGAMGR_RESET>;
|
|
altr,bitstream = "fit_spl_fpga.itb";
|
|
};
