TMS320F280049: How to change EMU-BOOTPIN-CONFIG

Part Number: TMS320F280049

Hi,

I want to debug my code after performing a reboot. But the EMU-BOOTPIN-CONFIG seems to be bad, so he stays in WAIT_BOOT.

How can I change the EMU-BOOTPIN-CONFIG, so that I can force FLASH_BOOT or standalone mode?

Best regards,

Stefan

    Stefan,

    Please check 4.6.1 Boot ROM Registers and 4.3.1 Configuring Alternate Boot Mode Pins in TRM (https://www.ti.com/lit/ug/sprui33b/sprui33b.pdf)

    Figure 4-2. Emulation Boot Flow describes the flow for emulation boot.  You can emulate standalone boot by configuring EMU_BOOTPIN_CONFIG_KEY as 0xA5.

    Let us know if you need further details.

    Thanks and regards,
    Vamsi

    Hi Vamsi,

    thanks for your reply. My problem was that I did not know how to change those registers. I tried using #pragma DATA_SECTION, but that did not work for me.

    But I realized I could just set all nibbles in EmuKey and EmuBMode to 0xA5. 

    Best regards,

    Stefan

    Hi Stefan,

    We have predefined function in Gel file also which you can use to set the emulation boot mode. You can access these function by clicking on "Scripts -> EMU Boot Mode Select -> EMU_BOOT_FLASH" in CCS after connecting to target.
