3.2.1 Part [INIT]
The part [INIT] defines a list of commands which should be executed every time the target comes out
of reset. The commands are used to get the target ready for loading the program file.
WGPR register value
Write value to the selected general purpose register.
register
the register number 0 .. 31
value
the value to write into the register
Example: WGPR 0 5
WSPR register value
Write value to the selected special purpose register.
register
the register number
value
the value to write into the register
Example: WSPR 27 0x00001002 ; SRR1 : ME,RI
WREG name value
Write value to the selected CPU register by name
name
the register name (MSR,CR,PC,XER,LR,CTR, ...)
value
the value to write into the register
Example: WREG MSR 0x00001002
DELAY value
Delay for the selected time. A delay may be necessary to let the clock PLL
lock again after a new clock rate is selected.
value
the delay time in milliseconds (1...30000)
Example: DELAY 500 ; delay for 0.5 seconds
WM8 address value
Write a byte (8bit) to the selected memory place.
address
the memory address
value
the value to write to the target memory
Example: WM8 0xFFFFFA21 0x04 ; SYPCR: watchdog disable ...
WM16 address value
Write a half word (16bit) to the selected memory place.
address
the memory address
value
the value to write to the target memory
Example: WM16 0x02200200 0x0002 ; TBSCR
WM32 address value
Write a word (32bit) to the selected memory place.
address
the memory address
value
the value to write to the target memory
Example: WM32 0x02200000 0x01632440 ; SIUMCR
FILL start size
Fill a memory range using 64-bit writes. Maybe used to initialize an ECC
protected memory range. The start address has to be on a 128 byte
boundary and the size has to be a multiple of 128 (0x80).
start
the start address of the memory range to fill
size
the size in bytes of the memory range to fill
Example: FILL 0x40000000 0x10000 ; fill ECC SRAM
