Part Number:OMAP-L138
Tool/software: Code Composer Studio
After programming the OMAP-L138 processor flash using a bin image generated using AISGen, I can not longer connect to either the ARM or DSP of my OMAP chip. Within the bin file, the ARM program simply brings the DSP out of reset. The DSP program was setup to initialize the part and spin.
I am using CCS 5.5 with a Blackhawk USB 560M to run emulation on my program designed hardware.
Within the target configuration, I am using a TI supplied gel file that is contained within c:\TI\ccsv5\ccs_base\emulations\boards\lcdkomapl138\gel\omap-l138_LCDK.gel.
When this gel executes on the ARM, I get the following error messages:
ARM9_0: GEL: Error while executing OnTargetConnect(): Page fault occurred reading 0x01E27800 at (*((unsigned int *) ((0x01E27000+0x800)+(4*LPSC_num)))&0x1F) [OMAP-L138_LCDK.gel:787] at PSC1_LPSC_enable(0, 0) [OMAP-L138_LCDK.gel:523] at PSC_All_On() [OMAP-L138_LCDK.gel:244] at OnTargetConnect() .

ARM9_0: Unable to determine target status after 20 attempts
ARM9_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
When attempting to connect to the DSP, I get the following error message:
C674X_0: Error connecting to the target: (Error -1143 @ 0x0) Device core was hung. The debugger has forced the device to a ready state and recovered debug control, but your application's state is now corrupt. You should have limited access to memory and registers, but you may need to reset the device to debug further. (Emulation package 5.1.232.0)
I am desperate need of being able to revive this board and program it with a different OMAP image. Unfortunately, this is the second board that we have gotten into a state where we can no longer connect the emulator to either the ARM or DSP. Any help in allowing me to revive these boards would be GREATLY appreciated!
Thanks in advance,
