Calling Device_cal from C in F28377D

Other Parts Discussed in Thread: CONTROLSUITE, TMS320F28377D

TMS320F28377D: Since V130 of device_support of ControlSuite Device_cal is defined in F2837xD_Examples.h as

#define Device_cal (void (*)(void))0x070282

Any ideas how to call it in C?

If I write:

(*Device_cal)();

the compiler does translate this to

MOVL XAR7, #0x070282
LCR *XAR7

The end of the function (found at 07035c) is LRET (and not LRETR)

So I must use a LC to call this function and not LCR.

Thank you for your ideas!

Hi Roger,

Devices which have been released thus far do not have the necessary trims to allow for a call to Device_cal(). You are correct in that the final instruction of the Device_cal() is an LCR. This has been corrected and changed to LRETR in our latest devices. I will work with the software team to create a function which checks whether the Device_cal() is ready to be called or not and have them release it in controlSUITE.

Best Regards,
Adam

Thank you Adam! So I will wait for the new controlSuite and not call Device_cal in the mean time.
Best regards
