Is it possible to Read Flash from unsecured code?

Shailesh,

If the CSM is not secured, then anything with access to the device can read the flash.  The debugger (Code Composer Studio) using a JTAG emulator pod for example.

Beyond JTAG, other access ports (e.g., serial port) would require software to be on the device already to handle the port interface, or they could use the ROM bootloader to load such software into the device.

Hi Sailesh,

As David has mentioned, it is easy to access the flash contents if CSM is not secured. CCS Uniflash can demonstrate the same. Check it out:  http://processors.wiki.ti.com/index.php/Category:CCS_UniFlash
