Description

This CCS GEL file can be used to debug boot issues, determine ROM revisions, and display other information such as PLL settings.

The GEL was created to work with all OMAP-L13x, AM1x, and C674x devices.

Download

Use the following GEL file with CCS3.3 or higher to display debug information after connecting:

OMAPL1x_debug_v8.zip

Directions

Directions for CCS 3.3

Connect to the processor, can be ARM or DSP of any OMAP-L1x, AM1x, or TMS320C674x device.
File -> Load Gel
Gel -> Run All

Directions for CCS 4.x and higher

Connect to the processor, can be ARM or DSP of any OMAP-L1x, AM1x, or TMS320C674x device.
Tools -> Gel Files
Right-click on the window and select "Load Gel"
Go to Scripts -> Diagnostics -> Run All

Note: Make sure the MMU is disabled when you run the scripts in order to properly read the registers. You can disable the ARM’s MMU in CCS by going to Tools -> Advanced ARM Features.

The GEL file will print out the following information:

ROM ID: Revision number of the boot ROM
Silicon revision number
Boot Mode: Current boot mode, as selected by the boot pins latched at reset
ROM Status Code: Current status of the ROM code
Description: Description of any error messages that the ROM may have encountered during boot
Program Counter: The current program counter of the connected device (ARM or DSP)
Device Information: Generic device information that may be helpful when getting support from TI
Clock information: PLLm_SYSCLKn is output
- Note: If your board uses an input clock other than 24 MHz you need to modify the definition at the start of the gel file accordingly.
