Hi,

I'm using CYBT-343026 and tried to build and program handsfree program.

CYBT-343026 has 512KB external flash and also 848KB of ROM memory inside CYW20706.

If I did not change something of make file;

Q1: Which ROM area will be used for program instruction area?

       External Flash(512KB)? or internal ROM memory(848KB)?

Q2: How can I see how much memory use the program of ROM/RAM?

       And, how can I see how much memory is stil free?

      The customer will have a plan to enhance program ,such as adding profile.

       In such case, the customer would like to know memory usage and free memory area for each application.

*******

Q3: Is there any way to change memory boot area from internal memory to external flash or something?

       If possible, I think we should change make file or setting of WICED Studio. Please tell me the way how to change it.

Thank you.

Hi ,

Q1: Which ROM area will be used for program instruction area?

       External Flash(512KB)? or internal ROM memory(848KB)?

A:  The code will be downloaded into External Flash and will be copied to the RAM.

      ROM will contain the stack Firmware etc, to which there is no external access.

Q2: How can I see how much memory use the program of ROM/RAM?

       And, how can I see how much memory is stil free?

A:  The application code will be running on the RAM.

      After building the project in WICED studio, you can check the  Build console for the application size

how can I see how much memory is stil free? - Around 180KB is available for the application code in the RAM. So the left out memory after building the project will be equal to 180KB - Application size from the console

Q3: Is there any way to change memory boot area from internal memory to external flash or something?

A: No.

Thanks & Regards,
Anjana
