LAUNCHXL-F28379D: Stuck inside InitSysCtrl() --> . . --> . . -->InitSysPll() function

Other Parts Discussed in Thread: C2000WARE

Hello there,

I have been experience this strange issue lately. This is related to InitSysCtrl() function specifically InitSysPll() function.

I have imported some examples which has InitSysCtrl() function in the main() and they work fine but when I create my own empty ccs project and added all those path for files and libraries, I stuck at the while() loop in InitSysPll() function. see below:

I checked the register value of ClkCfgRegs.SYSPLLSTS.bit.LOCKS, it shows '1' it still doesn't get out and hangs in there.

Thanks,

Sumit

    Hello Sumit,

    Did you create your empty project using the "empty driverlib" project available in C2000ware? Can you confirm what reference clock source you are using in your project - INTOSC, or external crystal? The configured PLL settings would be invalid for an external crystal - it appears to expect a 10MHz OSCCLK.

    Best regards,
    Ibukun

    Hello lbukun,

    I used the "empty drivelib project" this time and issue is still there. It looks like it uses the external crystal.

    thanks,

    Hello Sumit,

    One thing to check: Make sure you have F2837xD_Headers_nonBIOS.cmd in your project. You can find this file in <c2000ware_install_dir>\device_support\f2837xd\headers\cmd. We've seen issues before where the address of the register is incorrectly defined because the wrong cmd file is referenced.

    Best regards,
    Ibukun

    Ibukun,

    Adding F2837xD_Headers_nonBIOS_cpu1.cmd file does let it pass through InitSysCtrl().

    Thanks,
