CC2340R5: Does CC2340 support software breakpoint beside of hardware breakpoint?

Shuyang Zhong

Part Number: CC2340R5

My customer found that CC2340 Cortex-M0 core supports limited number of hardware breakpoint. For debug purpose they would like to know if CC2340 supports software breakpoints? If yes, how many software breakpoints does it support?

Hi Shuyang,

Please refer to the Debugging Guide https://dev.ti.com/tirex/content/simplelink_lowpower_f3_sdk_7_40_00_64/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index-cc23xx.html#breakpoints

Due to limitation of Cotex-CM0+, the number of breakpoints for CC23xx devices is 4. Check breakpoints limitation of ARM Cortex-CM0+. During programming stage, debugger will use 3. Breakpoints set by application will be ignored if more than one breakpoint is used by the application. It is possible to gain one more breakpoint back by implementing the following steps. Right click on the project, go to Debug As->Debug Configuration->Target, unchecked ‘Enable CIO function use’.

I hope this will help,

Best regards,
