TMS320F28377D: Call of "Device_cal"

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Hello experts,

in TRM "Device_cal" is referenced as a function to fetch ADC and DAC trim values from the OTP.

In some C2000ware examples, "Device_cal" is called during system initialization only if the symbol "_FLASH" is not defined.
I understand that the function call should only be made when the program is running with a debugger.

Does it cause problems if the function is always called?

Regards,

Jan,

There is no harm in calling this function multiple times, it just may not be necessary. This function is called in the boot ROM before the boot mode takes effect which is why you see the option to not explicitly call it again. For RAM only code, and esp on CCS the Boot ROM is typically bypassed and this is why the function is included in our examples as part of the system init.

Best,
Matthew
