RANGE bit (used to connect one watchpoint with the other one) are automatically
masked out. In order to use these bits you have to set the watchpoint by writing the
ICE registers directly.
Syntax
setWP <Addr> [<AccessType>] [<Size>
] [<Data> [<DataMask> [<AddrMask>]]]
Example
setWP 0x20000000 W S8 0xFF
3.2.1.41 sleep
Waits the given time (in milliseconds).
Syntax
sleep <Delay>
Example
sleep 200
3.2.1.42 speed
This command sets the speed for communication with the CPU core.
Syntax
speed <Freq>|auto|adaptive
Parameter Meaning
Addr Address to be watchpointed.
Accesstype
Specifies the control data on which data event has been set:
R: read access
W: write access
Size
Valid values: S8 | S16 | S32
Specifies to monitor an n-bit access width at the selected address.
Data Specifies the Data on which watchpoint has been set.
DataMask
Specifies data mask used for comparison. Bits set to 1 are masked
out, so not taken into consideration during data comparison. Please
note that for certain cores not all Bit-Mask combinations are sup-
ported by the core-debug logic. On some cores only complete bytes
can be masked out (e.g. PIC32) or similar.
AddrMask
Specifies the address mask used for comparison. Bits set to 1 are
masked out, so not taken into consideration during address compar-
ison. Please note that for certain cores not all Bit-Mask combina-
tions are supported by the core-debug logic. On some cores only
complete bytes can be masked out (e.g. PIC32) or similar.
Parameter Meaning
Delay Amount of time to sleep in ms.
Parameter Meaning
Freq Specifies the interface frequency in kHz.
auto Selects auto detection of JTAG speed.
adaptive Selects adaptive clocking as JTAG speed.
