Other Parts Discussed in Thread: DM3730, DM3725
Hello,
I want to create a first and simple project for the BeagleBoard xM, but unfortunately I get always a problem to connect to the processor core "CortexA8".
My installation:
• Windows 7 Professional, Service Pack 1, 64-bit system
• Code Composer Studio version 5.5.0.00077
• Spectrum Digital XDS560V2 STM USB Emulator
• Evaluation board BeagleBoard xM, Rev C
First, I created a new CCS project with the following settings:
• Device Variant: BeagleBoard_xM
• Project template: SYS/BIOS > TI Target Examples > Typical
In the project configuration file "BeagleBoard_xM.ccxml", tab "Basic", I've set the connection and selected again the device "BeagleBoard_xM". The "Test Connection" was successful, and so was also the project build.
To prepare the debugging I configured the initialization in the configuration file "BeagleBoard_xM.ccxml", tab "Advanced", and selected the GEL file "am_dm37x_cortexA.gel" for the core "CortexA8". This seems to be the appropriate one, since the mentioned board has a DM3730 processor. I downloaded the related GEL files from the following site:
http://processors.wiki.ti.com/index.php/OMAP_and_Sitara_CCS_support#DM3730_and_DM3725
Now I can start a debug session, which works fine so far, but when I want to connect to the core "CortexA8" I get the following error message:
Cortex_A8_0: Trouble Writing Memory Block at 0x48004c10 on Page 0 of Length 0x4: (Error -1065 @ 0x48004C10) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)
Cortex_A8_0: GEL: Error while executing OnTargetConnect(): Target failed to write 0x48004C10 at *((int *) 0x48004C10)=0x20 [am_dm37x_cortexA.gel:427] at Watchdog_disable() [am_dm37x_cortexA.gel:218] at OnTargetConnect() .
Cortex_A8_0: Trouble Reading Register CP15_Registers_CP15_CONTROL_REGISTER: (Error -2131 @ 0x20013F00) Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)
Do I need another GEL file? Or does the core connect require any preceding, manual script calls?
Regards, Stéphane
