CCS/MSP430FR2633: CCS stopping at non-existent breakpoints (solved)

Fred Murphy
Intellectual 420 points

Part Number: MSP430FR2633

Tool/software: Code Composer Studio

I'm posting about this issue despite it already being solved, as I see a number of posts about CCS stopping at "ghost breakpoints" but none seem to have a definite answer. My MSP430FR2633 based custom board kept stopping at hardware breakpoints despite none being set. It often appeared to be at the same point but this may have just been code that was frequently run.

Anyway, in this post Walter Schnoor wondered if running with a MCLK of 16MHz was the issue. I dropped mine down to 8MHz and the problem went away. So I'd say "yes". Unfortunately that thread is locked so I can't confirm there. I thought I'd post an answer here for anyone else with a similar problem. I'd originally asked in the CCS forum but it does seem to be a hardware issue.

    Fred,

    Thank you for taking your time to explicitly confirm the thought that Walter had about MCLK and hitting the phantom breakpoints. We always appreciate when customers post solutions to problems they are experiencing so that others experiencing the same issue can find the work-around faster.

    Best regards,

    Matt
