    • Type: Bug
    • Resolution: Unresolved
    • Priority: High

      Hardware breakpoints are only available on the first device of multiple daisy chained devices. There are no issues with software breakpoints. Other debug actions like connect, load, run, read/write registers/memory, etc also work fine. Operations like source stepping code in flash (asm stepping is fine) can be impacted since that action could require a breakpoint.

      There are no issues at all with the first device.

      Note that bypassing the first device so that only the second device is debuggable does not help. It appears only the device physically first on the scan-chain is unaffected by this issue.

      This appears to be a regression of https://sir.ext.ti.com/jira/browse/EXT_EP-10378, which was fixed in CCS 20.4.1. The issue appears again in CCS 20.5.0 and CCS 21.0.0.
