GEL FILES

CCSTUDIO-SITARA: GEL file errors

Hi,

I'm trying to upload GEL file to AM4378 with XDS200 JTAG probe / CCS v10 and I'm getting some errors when trying to load the GEL file and run the scripts.

AM43xx_DDR3_config() cannot be evaluated.
identifier not found: CM_PER_EMIF_CLKCTRL
at (unsigned int *) CM_PER_EMIF_CLKCTRL [AM43xx_EMIFconfig_HWlvl3.gel:14]
at EMIF_PRCM_CLK_ENABLE() [AM43xx_EMIFconfig_HWlvl3.gel:78]
at AM43xx_DDR3_config()

GEL file as attached:

AM43xx_EMIFconfig_HWlvl.gel

There seems to be some deficiencies in data types, register definitions and function definitions. Is there a sample GEL file with these attached? Why are there errors in this GEL file for EVM, do I need to use it with an old CCS? Can you provide an example of a properly working DDR GEL file?

    There are several GEL files for AM43xx which depend on each other.  You can't just load up the one for the EMIF.  If you create a target configuration for the GP EVM in CCS, and you will see an example of all the different GELs that are needed.

    Regards,
