CCS/TMS320F28377S: Avoid program OTP for first step validation

Hi Stephane,

I assume you are referring USER OTP here. USER OTP has the security configuration which user need to program if planning to secure the device. If not then user need not to program it default value in USER OTP will be good.  I am not clear why are you getting a TRAP error though.

Dear Vivek,

I refer to OTP programmed by TI for DSPs in production because marking contains "TMS" word.

I have two cases where getting TRAP error:

Temperature:

if(DevCfgRegs.REVID >= 3)

{

//

//for production devices (Rev. C), pull the slope and offset from OTP

//

tempSensor_tempSlope = (int32)getTempSlope();  --> TRAP Error here

tempSensor_tempOffset = getTempOffset();

}

else

{

//

//for pre-production devices, use these static values for slope

//and offset

//

tempSensor_tempSlope = 5196;

tempSensor_tempOffset = 1788;

}

and second case:

void AdcSetMode(Uint16 adc, Uint16 resolution, Uint16 signalmode)

{

Uint16 adcOffsetTrimOTPIndex; //index into OTP table of ADC offset trims

Uint16 adcOffsetTrim; //temporary ADC offset trim

//

//re-populate INL trim

//

CalAdcINL(adc);

if(0xFFFF != *((Uint16*)GetAdcOffsetTrimOTP)) :---> TRAP Error

{

I think this address are not defined. Nevertheless Eval Board (LAUNCHPAD) work fine with this code.

Ok, understood. These functions are supposed to be programmed by TI. Can you take a picture of your device (top view) and send it.
