TMS320F28379D: How to connect emulator and erase the chip

Hi,

I have no "OnChip Flash" in menu Tools. The menu is present in debug perspective only. 
I use CCS 11.1.0.00011

I cannot connect, and when I try I receive the message:

How to connect without programming?

Kind regards,

You need to use TargetConfiguration view and select the correct target configuration file, right click on it and launch it. After launching the target configuration, right click on the CPU target and click on connect.

Hi,

When I launch the configuration as you instructed it starts fine.
Unfortunatelly, when I try to connect I have following error:

PS
I upgraded CCS to v12.

Do you have WAIT BOOT mode on the board ?

No, I have not. I have no jumpers to change it. I don't know what is set in boot ROM.

My bootloader in flash is started and it sets up at the beginning of the main():

//EMU_BOOTCTRL = EMU_BOOT_FLASH | EMU_KEY
*(Uint32 *)0xD00 = 0x0B5A;

I found boot pins on the board, I was able to control them. 

I hold following logic states during power on (they correspond to wait boot mode):

GPIO72 1
GPIO84 0

and the program from BootROM did not start my bootloader (that one in flash memory) but remained in its space at address 0x3FF16A.
Then I connected to target as you said in CCS. Next in On-Chip Flash tab there was Unlock button.

Thank you for your help.

I found in the chip documentation that wait boot should happen if the emulator is connected. Why it was not in my case?
(I use xds100v3)

Can you please send the snapshot from documentation which has this reference.

Hi,

I have GPIO72 and 84 pulled up, so they are logic ones at power up. This means that GetBootMode/Flash is selected. In the documentation there is a statement:

So I concluded that connection the emulator is enought to enter wait mode in bootROM.

Hi,

Thank you for your help.
Yestarday, I did marked by 'This resolved my issue' your first answer - there was everything about the question. Further discussion were detailes and the help me to understand. I thought about another people when they find the question and what is the main resolution that will be highlighted. 

Should I mark the last one as well? or close this question some another way?
