PIC32MZ[DA] Starter Kit
|
||||
----------------------------------------
|
||||
PIC32MZ[DA] Starter Kit is based on PIC32MZ[DA] family of micro-controller.
|
||||
This family is powered by MIPS M14KEC 32bit general purpose core and has
|
||||
advanced microcontroller features and peripherals.
|
||||
|
||||
This processor boots with proprietary stage1 bootloader running from internal
|
||||
boot-flash. Stage1 bootloader inturns locates and jumps to U-Boot programmed
|
||||
on internal program-flash. Finally U-Boot loads OS image (along with other
|
||||
required files for booting) from either uSD card, or ethernet, or from USB
|
||||
storage.
|
||||
|
||||
To boot Linux following three files are mandatory - uEnv.txt (custom U-Boot
|
||||
environment file), uImage, *.dtb (platform device-tree-blob file).
|
||||
|
||||
U-Boot jumps to Linux using UHI specification.
|
||||

||||
