* Microchip PIC32MZDA Platforms
|
||||
|
||||
PIC32MZDA Starter Kit
|
||||
Required root node properties:
|
||||
- compatible = "microchip,pic32mzda-sk", "microchip,pic32mzda"
|
||||
|
||||
CPU nodes:
|
||||
----------
|
||||
A "cpus" node is required. Required properties:
|
||||
- #address-cells: Must be 1.
|
||||
- #size-cells: Must be 0.
|
||||
A CPU sub-node is also required. Required properties:
|
||||
- device_type: Must be "cpu".
|
||||
- compatible: Must be "mti,mips14KEc".
|
||||
Example:
|
||||
cpus {
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
|
||||
cpu0: cpu@0 {
|
||||
device_type = "cpu";
|
||||
compatible = "mti,mips14KEc";
|
||||
};
|
||||
};
|
||||
|
||||
Boot protocol
|
||||
--------------
|
||||
In accordance with Unified Hosting Interface Reference Manual (MD01069), the
|
||||
bootloader must pass the following arguments to the kernel:
|
||||
- $a0: -2.
|
||||
- $a1: KSEG0 address of the flattened device-tree blob.
