This section describes the steps to use a third party debugger on the ARM926EJ-S within the device. The debug capabilities and features for DSP and ARM are as shown below.
DSP:
Category | Hardware Feature | Availability |
---|---|---|
Basic Debug | Software breakpoint | Unlimited |
Hardware breakpoint | Up to 10 HWBPs, including: | |
4 precise(1) HWBPs inside DSP core and one of them is associated with a counter. | ||
2 imprecise(1) HWBPs from AET. | ||
4 imprecise(1) HWBPs from AET which are shared for watch point. | ||
Analysis | Watch point | Up to 4 watch points, which are shared with HWBPs, and can also be used as 2 watch points with data (32 bits) |
Watch point with Data | Up to 2, Which can also be used as 4 watch points. | |
Counters/timers | 1x64-bits (cycle only) + 2x32-bits (water mark counters) | |
External Event Trigger In | 1 | |
External Event Trigger Out | 1 |
ARM:

8 imprecise(1) HWBPs from ETM’s address comparators, which are shared with trace function, and can be used as watch points. | ||
4 imprecise(1) HWBPs from ICECrusher. | ||
Analysis | Watch point | Up to 6 watch points, including: |
2 from ARM core which is shared with HWBPs and can be associated with a data. | ||
8 from ETM’s address comparators, which are shared with trace function, and HWBPs. | ||
Watch point with Data | 2 from ARM core which is shared with HWBPs. | |
8 watch points from ETM can be associated with a data comparator, and ETM has total 4 data comparators. | ||
