Hiii,
I am working on C28x F28027 mc with CCSv6, here am facing connecting issue (Error:1135 and sometimes Error:1015)
I just tried to write code on flash memory and retrive it from Flash to ram while restart mc.
I refered the document (controlSUITE_DSP2802x_HeaderFiles_Quickstart_Readme)controlSUITE_DSP2802x_HeaderFiles_Quickstart_Readme.pdf from controlSUITE to get the code from flash to RAm.

In section 4.5 upto 4 sub sectons i was considered

I just copy the below documents from conrolSUITE with out any modification.
DSP2802x_MemCopy
DSP2802x_CSMPasswords.asmCSMPassword_asm.rar

wether my device got lock, or some other issue?
If my device got lock, how should i unlock?

Appriciate for any valuable advices.

Regards,

Narsimha.

    If you flashed the device using the CSM Passwords assembly file and linker command file, then you likely flashed the passwords into the CSM registers and locked the device.

    You you should be able to connect to the device when you put it in wait boot mode. Boot the device to WAIT BOOT Mode and then try to connect via JTAG. Then you should be able to look at the CSM passwords in flash and see what they are in order to unlock it if you wish to do so.
