tool: D259: Command help


tool: D215:     Commands are case insensitive

tool: D218:     Address and numeric values can be dec (ex 12), hex (ex 0xC), or octal (ex 014)

tool: D368:     Memory addresses can be wa=32-bit word address, ba=byte address.  Suffix of i=instruction or d=data memory

tool: D463:     Return without a command will rerun a previous d, dd, or di command while displaying the next block


tool: D526:     BR [breakpoint_number [address]]

tool: D140:     View or set an instruction breakpoint

tool: D3:        'b' by itself will display current breakpoints

tool: D249:        breakpoint_number is the breakpoint reference and ranges from 0 to %u


tool: D42:        address is the instruction word address that the processor should stop at (instruction is not executed)

tool: D376:        if no address is provided, then the breakpoint is cleared


tool: D69:     D memory_location_wa [length]

tool: D148:     Raw dump of PRU data memory (32-bit word offset from beginning of full PRU memory block - all PRUs)


tool: D392:     DD memory_location_wa [length]

tool: D114:     Dump data memory (32-bit word offset from beginning of PRU data memory)


tool: D334:     DI memory_location_wa [length]

tool: D457:     Dump instruction memory (32-bit word offset from beginning of PRU instruction memory)


tool: D17:     DIS memory_location_wa [length]

tool: D200:     Disassemble instruction memory (32-bit word offset from beginning of PRU instruction memory)


tool: D278:     G

tool: D88:     Start processor execution of instructions (at current IP)


tool: D111:     GSS

tool: D414:     Start processor execution using automatic single stepping - this allows running a program with breakpoints


tool: D23:     HALT

tool: D277:     Halt the processor


tool: D269:     L memory_location_iwa file_name

tool: D72:     Load program file into instruction memory at 32-bit word address provided (offset from beginning of instruction memory


tool: D488:     PRU pru_number

tool: D18:     Set the active PRU where pru_number ranges from 0 to %u


tool: D433:     Some debugger commands do action on active PRU (such as halt and reset)


tool: D305:     Q

tool: D205:     Quit the debugger and return to shell prompt.


tool: D493:     R

tool: D189:     Display the current PRU registers.


tool: D313:     RESET

tool: D8:     Reset the current PRU


tool: D161:     SS

tool: D157:     Single step the current instruction.


tool: D254:     WA [watch_num [address [value]]]

tool: D273:     Clear or set a watch point

tool: D356:       format 1:  wa - print watch point list

tool: D477:       format 2:  wa watch_num - clear watch point watch_num

tool: D377:       format 3:  wa watch_num address - set a watch point (watch_num) so any change at that word address

tool: D163:                  in data memory will be printed during program execution with gss command

tool: D139:       format 4:  wa watch_num address value - set a watch point (watch_num) so that the program (run with gss) will

tool: D34:                  be halted when the memory location equals the value

tool: D326:       NOTE: for watchpoints to work, you must use gss command to run the program


tool: D271:     WR memory_location_wa value1 [value2 [value3 ...]]

tool: D66:     Write a 32-bit value to a raw (offset from beginning of full PRU memory block - all PRUs)

tool: D504:     memory_location is a 32-bit word index from the beginning of the PRU subsystem memory block


tool: D265:     WRD memory_location_wa value1 [value2 [value3 ...]]

tool: D81:     Write a 32-bit value to PRU data memory (32-bit word offset from beginning of PRU data memory)


tool: D227:     WRI memory_location_wa value1 [value2 [value3 ...]]

tool: D239:     Write a 32-bit value to PRU instruction memory (32-bit word offset from beginning of PRU instruction memory)
