IAR Debugger failure

Other Parts Discussed in Thread: CC2540

Any time after the following is run, the IAR debugger fails to show correct values for static variables ("Statics" box).

        SLEEPCMD |= OSC32K_CALDIS;           // don't allow auto cal of 32KHz
       CLKCONCMD = (CLKCONCMD & ~(CLKCON_CLKSPD | CLKCON_OSC)) | CLKCON_CLKSPD_16M;
       while(CLKCONSTA & CLKCON_OSC);

Code & breakpoints continue to run properly, but cannot debug viewing static variables.

Have I set up IAR options wrong? I don't see problem in the simple rosc/xosc software examples workspace provided by TI (clk_hs_xosc.c).

Thank you,

Hi Gi,

Your problem may be that the debugger is not able to communicate correctly with the device if the CLKSPD is anything other than the available maximum. It seems like you set the CLKSPD to 1 instead of 0 (signifying that the 32MHz theoretical max clock is divided by 2^1 instead of 2^0) while running on the 32MHz oscillator.

See chapter 3.1 of the CC2540/41 user's guide.

Best regards,
Aslak

That was it exactly. Thank you.
