5.1.1 Loading by CCS (JTAG)

Loading the project to CCS is exactly the same as loading any other .out file by the flash plugin tool.

  1. Launch the F29H850TU9.ccxml file as Project-less Debug
    1. The F29H850TU9.ccxml file can be found in the TargetConfig folder of the project
  2. Connect to CPU1
  3. Verify that the device is in either bank mode 1 or bank mode 3
    1. SSU_GEN_REGS.BANKMODE is 0x6 (mode 1) or 0xC (mode 3)
    2. Right-click CPU1 -> Properties
      1. Category drop-down menu -> Flash Settings
      2. Make sure bank mode 1 or 3 is selected
      3. Only select Program BANKMGMT if the device is not in one of these two modes already. If not, then program the BANKMGMT and issue a device reset
  4. Select Run -> Load -> Load Program -> flash_based_uart_sbl_with_fota.out

If users want to program the flash-based SBL to the inactive address space, then make sure the FOTA enable checkbox is checked in the flash plugin before loading.

Once these steps are completed, flash-based SBL is loaded to flash and is ready to execute.
