Hi,

My program to execute on the board requires around 800 Kilo Bytes of heap memory, code and data sizes of around 1 MB.

On board RAM present is upto 256 Kilo bytes.

So I want to increase the board RAM size.

How to add an external RAM to this board?

There is 256KB of RAM internal to the device and 8MB of SDRAM on the HDK board. There is 3MB of internal flash on the device. The internal device memory sizes are listed on the first page of the device data manual (http://www.ti.com/lit/ds/symlink/tms570ls3137.pdf). The features of the HDK are listed on page 5 of the User's Guide (http://www.ti.com/lit/ug/spnu509b/spnu509b.pdf).

Best regards,
