TMS320F28377S: Device_cal Address

Andrew Barnett

Part Number: TMS320F28377S
Other Parts Discussed in Thread: C2000WARE

What is the correct address for the Device_cal function?

In the various example projects for f2837xs it is given as: #define Device_cal (void (*)(void))0x070282

yet in the file:

C:\ti\c2000\C2000Ware_1_00_06_00\libraries\boot_rom\f2837xs\revB\rom_sources\F2837x_bootROM\cpu01-bootROM\include\c1_bootrom.h

it is defined (line 129) as: #define DEVICE_CAL_LOCATION 0x70280

Which of these is correct, or does it not matter?

Also, if I'm running in debug mode using the emulator, will the various ADC trim and offset registers be populated as long as I call this function, as well as CalAdcaINL, CalAdcbINL, GetAdcOffsetTrimOTP?

Thanks in advance for any insight.

Hi Andrew,

Only for the F2837x family of devices, device cal can reference either address 0x70280 or 0x70282. The first two locations of the device cal, which starts at address 0x70280, are NOP instructions so referencing either locations is fine. Good point you mentioned that when debugging in emulation mode, you need to run the device cal or the other cal subfunctions in order for the trim registers to be populated.

Regards,

Joseph
