Hi,
i am a beginnner in this field.am using logicpd experimenter kit omapl138.I tried flashing the sample ARM-DSP-LED programs provided by TI.The combined binary file is perfectly working with ROM BOOTLOADER,after flashing to SPI1 FLASH memory.Now,i tried with my required application in which ARM and DSP has to interrupt each other in between.my code is working properly with JTAG,but when i converted the out files to a combined binary and wrote to Flash,its not working properly with bootloader.In my application,ARM has to interrupt DSP after performing some task and DSP after performing some task has to interrupt back ARM.In our observation,DSP is getting initialised but its not getting interrupted by ARM and moreover,ARM is getting restarted.i am providing with my DSP command file and configuration file uesd in AIS.
