TMS320F28377D: How to recognize emulation mode by user code

vesgine

For 28377D, the boot flow is different between emulation mode and standalone
mode. In emulation mode, CPU1 doesn't need to send IPC command to boot CPU2.
So in the project of CPU1, the code like "IPCBootCPU2(
C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH)" should not be used in emulation mode.

Sometimes, I have to debug the code in standalone mode. It means the code
like "IPCBootCPU2(C1C2_BROM_BOOTMODE_BOOT_FROM_FLASH)" should be used.

Is there any method for CPU1 to recognize emulation mode when debugging with
CCS? such as checking some register value.

Vesgine,

You can use RESC (Bit 31). TRSTn_pin_status register bitfield.

If RESC.TRSTn_pin_status (Bit 31) = 1, then JTAG is connected. So, device boots in emulation boot mode

If RESC.TRSTn_pin_status (Bit 31) = 0, then JTAG is not connected. So, device boots in standalone boot mode.

Regards,

Manoj
