Hello!!!!!!!!!
I'm using an AT91SAM9X35 Board..and i wanted to load a application code to DDR2SDR(Secondary RAM) directly through keil download option or through sam-ba software....is it possible?????????????
Thank you!!!
You'd likely need to make a debugger script (.INI) which initializes the pins, the memory controller and the SDRAM, and then LOAD %L to code into the memory. Uncheck "Load Application at Startup", and point to the initialization file.
Several of ATMEL boards have DebugInSDRAM.ini type examples.
Thank You Pier Sorry for late Response.
1) I'm not getting this --> LOAD %L to code into the memory
2) I'm Refereeing Blinky_led program given in KEIL ATMEL software package.They have given .ini file for both internal RAM and EXT. SDRAM. as you said In the .INI file of the Ext.SDRAM they are the initialized the Pins and Ext.SDRAM ,Now I wanted to load my blinky led application code directly to SDRAM. I Uncheck "Load Application at Startup", and point to the initialization file.
3) Similarly i not able load my led application code internal RAM also.
I'm getting FLASH DOWNLOAD FAILED ERROR when i'm going to Downlod the code.
