[FAQ] AM64x / AM24x: How to use Code Composer Studio (CCS) to connect to PRU_ICSSG?

AM64x GP EVM (TMDS64GPEVM):

1) Set up CCS as per https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/08_00_00_21/exports/docs/api_guide_am64x/CCS_SETUP_PAGE.html . When creating the Target Configuration, do NOT bypass the ICSS_G cores. Go to the Advanced tab and verify that the DMSC will run an initialization script:

2) Flash the SOC Initialization binary as per https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/08_00_00_21/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html 

3) Set the boot switches to OSPI Boot as documented at https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/08_00_00_21/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html#BOOTMODE_OSPI . When CCS is connected to the UART to USB micro USB port and the board boots, you should see the NULL Bootloader execute:

4) Connect to the XDS100 micro USB port as shown here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/08_00_00_21/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html#EVM_CABLES . Boot the board, and start the Target Configuration.

5) For SDK 8.1 and earlier, the OPSI SBL NULL initialization binary does not enable PRU clocks. So if you try to connect to a PRU core at this point, it will fail like this:

6) If the PRU clocks are not enabled, you need to run an additional step. Connect to the DMSC. It will run the initialization GEL scripts by default.

7) You can finally connect to an ICSSG core! A successful connection will look like this:
