TMS320F28379D: Where is EMUKEY set when debugging in CCS?

Sasaki-san,

This is not set in BOOTROM code. This need to set by user via CCS memory watch window. You connect to CCS and then open CCS memory watch window and then write appropriate value at address 0xD00 and then reset the CPU and run. Gel also have some pre-defined function which can be used to set these.

Hi Vivek-san,

Thank you for your reply.

When connected to the device by CCS, 0xD00 is 0x5A. Why is this?

For example, if I write 0xFF in 0xD00 from the CCS memory browser, then disconnect and connect in CCS, 0xD00 would be 0x5A.

Hi Sasaki-san,

Do you have valid code in flash when powering-up the device ? If not can you try same with having valid code in flash.

Yes, I do. I loaded the "blinky_dc_cpu01" into FLASH.

Hi Vivek-san,

Thank you for your reply.

I understand.
BTW, where in boot rom does the device write the value to 0xD00?
I'm checking the boot rom source code but can't find it.
