Debugger problems

ralu — Mon, 13 Aug 2012 22:53:12 GMT

Debuuging does not work any more for CW 7.1 on MCF52235, because it looks like tha only one interrupt source works.

I can put one breakpoint, but after stop i can not make any steps, becuase it lost conenction.

I do not know why, but it can be due to drivers on PC or drivers on Multilink, but how can is solve this issue?

EDIT

I have two Multilinks Here (rev C and rev D) I also have two boards to test on. Uploading FW works fine, but debuuging lost connection after first breakpoint.

Are you disabling the PST data pins / setting them to other functions?

/* Enable debug */ #ifdef DEBUG MCF_GPIO_PDDPAR = 0x0F; // PST/DDATA Pins enabled #else MCF_GPIO_PDDPAR = 0; // Disabed - reduces EMC #endif

Issue was that due to use of some software from pe-micro debugger got impropper FW.

I got new FW for multilink FE from pe-micro support.

Is this in the BDM driver somewhere, or just in the code?

We have an issue where the BDM is setting MCF_GPIO_PDDPAR = 0x0F, and we don't want that.

We need to use the PST pins as gpio.

Thanks,
