Lattice MachXO2 Slave SPI FPGA Manager
|
|
|
|
Lattice MachXO2 FPGAs support a method of loading the bitstream over
|
|
'slave SPI' interface.
|
|
|
|
See 'MachXO2ProgrammingandConfigurationUsageGuide.pdf' on www.latticesemi.com
|
|
|
|
Required properties:
|
|
- compatible: should contain "lattice,machxo2-slave-spi"
|
|
- reg: spi chip select of the FPGA
|
|
|
|
Example for full FPGA configuration:
|
|
|
|
fpga-region0 {
|
|
compatible = "fpga-region";
|
|
fpga-mgr = <&fpga_mgr_spi>;
|
|
#address-cells = <0x1>;
|
|
#size-cells = <0x1>;
|
|
};
|
|
|
|
spi1: spi@2000 {
|
|
...
|
|
|
|
fpga_mgr_spi: fpga-mgr@0 {
|
|
compatible = "lattice,machxo2-slave-spi";
|
|
spi-max-frequency = <8000000>;
|
|
reg = <0>;
|
|
};
|
|
};
