Fields
Field

Description
unsigned int
struct arm
bool
Specifies if there should be a bypass before a JTAG restart.
Function for determining why debug state was entered.
Function for changing from Thumb to ARM mode.
Function for reading the core registers.
void (*)(struct target *target, uint32_t mask,
void *buffer, int size)
Function for reading CPSR or SPSR.
Function for writing to CPSR or SPSR.
Function for writing an immediate value to CPSR or SPSR.
Function for writing to the program counter.
Function for setting DBGRQ if the normal way won't work.
Callback function called after entering debug mode.
Callback function called before restoring the processor context.
int (*)(struct target *target, target_addr_t address,
uint32_t size, uint32_t count, const uint8_t *buffer)
Variant specific memory write function that does not dispatch to bulk_write_memory. Used as a fallback when bulk writes are unavailable, or for writing data needed to do the bulk writes.
int (*)(struct target *target, target_addr_t address,
uint32_t count, const uint8_t *buffer)
Write target memory in multiples of 4 bytes, optimized for writing large quantities of data.

Description
Probe EmbeddedICE module and set up local records of its registers. Different versions of the modules have different capabilities, such as hardware support for vector_catch, single stepping, and monitor mode.
Setup an ARM7/9 target's embedded ICE registers for software breakpoints.
Clear watchpoints for an ARM7/9 target.
Assign a watchpoint to one of the two available hardware comparators in an ARM7 or ARM9 target.
