F29H85X-SOM-EVM: Bit fields in CPU2 F29h85x (Flash Configuration).

Hi Shashank,

Can you send a copy of your linker cmd file and generated .map file for this project?

Kind regards,

Skyler

Hi Skyler,

I am unable to access the .map file because our PC is not connected to the internet. Is there anything specific I should check or try in this case?

Thanks and Regards 

Shashank 

Hi Shashank,

Where are these output sections being mapped to?

Kind regards,

Skyler

Hi Skyler,

Those sections are mapped into ti.bound section.

Hi Shashank,

Okay, let me reassign this thread to the correct expert and they will be able to assist you in the next day.

Hi Shashank,
Any reason you are using the RAM autoinitialization model, instead of ROM model?

Hi Samritha,

1. For cpu2, it doesn't have access to flash, its code should be run from RAM itself, I am loading program into FLASH and running it from RAM.

2. What is RAM Auto initialisation?

Regards, 

Shashank 

I am using bit fields to initialise the peripherals.Those peripherals are shown in warning initialised using bit fields.

Why are you using --ram_model here? Any particular reason?

I think it is default setting, I am getting that warning when I built program in Flash Build configuration.

Samritha,

I am used bit fields to initialize the Cpu Timer0 in CPU2, changed to ROM model, which making Cpu2 execute autoinit.h how to resolve this issue.

Can you share which example you are seeing the default to be ram_model if it is from our F29H85x-SDK.
Are you creating a single .out file, like in the SDK?

Please share more details about the issue in CPU2.

Regards,
Samritha

Samritha,

This is the multi-core empty project(not from SDK). 

It is creating cpu1 .out which includes cpu2 .out and cpu3 .out file.

in Flash Build Configuration it is deleting cpu3 .out file

I am used bit fields to program Pipe, timer, EPWM and adc modules 

Which are highlighted in generated warning. 

Project run time environment is in - RAM model.

Hi,
You can use the rom_model then.

Thanks,
Samritha

Cpu2 is executing functions in autoinit.h file. What it means, and how to resolve this issue?

Thanks, Regards 

Shashank 

What do you mean by executing functions in autonint.h file ? Can you elaborate.
Also, share the error if you are getting any.

Regards,
Samritha

Yes, you are right.

It is not generating any error, (CPU2 is executing functions in autoinit.h file).

Regards,

Shashank

Ok, what is the issue you are facing?
Can you provide more details about the autoinit.h functions you see.

Regards,
Samritha

Hi,

Now not facing the issue,

• But sometimes Cpus are executing functions in autoinit.h, ( functions in compiler header files) not entering main() again. 
• in what situations autoinit.h functions are executed (is there any relationship between RAM or ROM Model)?
• We are running Cpu2 code in the RAMs (as it is not having access to flash), but its code is stored in FLASH, which model will be appropriate for Cpu2 (RAM model or ROM model)

Thanks and Regards,

Shashank

Hi,
Do let us know the scenarios in which you are facing the issue. I could not reproduce it for now.
