5.4 Connect to the AM26x R5F Core

Launch the Target Connection

If the JTAG scan-test is successful, then right-click the Target Configuration ccxml file → Launch Selected Configuration.

Connect to the AM26x

Once loaded, right-click on the R5_0 core and click Connect Target in the Debug window.

Connect Target Figure 5-9 Connect Target

Observe the console output. If the output console is not visible, then select View → Console in Code Composer Studio.

Connecting to the AM26x target automatically loads GEL (General Extension Language) files to the AM26x R5F Core to initialize the AM26x device. This includes configuring device clocks, enabling peripheral clocks, and unlocking control registers.

Alternative GEL File Loading Method

GEL files can also be manually loaded to the AM26x device. While this is not recommended for initial bring-up, this allows for more customization and bring-up of specific device blocks, rather than the entire set of AM26x peripherals.

  1. Right-click the R5_0 Core and click Open GEL Files View.
    Open GEL Files View Figure 5-10 Open GEL Files View
  2. A window displaying the GEL files opens. Device-specific GEL files can be found at {CCS_install_path}/ccs[version]/ccs_base/emulation/gel/[device_name].
Note: GEL files are only compatible with the target device. AM263x GEL files are only compatible with AM263x, and so forth.

If no errors are observed in the output console, then JTAG connection to the device is verified.
