DM6446 Debugging DSP

Hi,

I have added the GEL scripts in the ARM9_0 and C6400PLUS_0 properties "GEL File".

"will not automatically run the on connect portion of the GEL which automatically does most of the GEL configuration"
Ah! That explains that then.

Thanks Bernie.

I re-downloaded the script from spectrum digitals website and re-entered the path (locally, was on a network before). I was then getting a warning about the script stuck in an infinite loop; there are 3.

Becuase of this Ive removed it and put it as a menu option with more prints...

The script now loads, but gets stuck at the first hurdle:
"
Taking DSP out of reset
Wait for state transtion to finish...

"

This is the message I get if I try and connect to the DSP,,,

Error connecting to the target:
Error 0x80000244/-1137
Fatal Error during: Register, Initialization, OCS,

It appears that the target is being held in reset.  This may be
due to Wait-In-Reset (WIR) configuration set by the EMU0=0
and EMU1=1 pin settings.  If this is the case, DISCONNECT
all CONNECTED devices including icepick and then select
RETRY to clear the WIR configuration.

This is odd, I am curious if you are using the same boot mode settings as I am, I have my switches set like the image below and I can connect to the ARM as long as I do it quickly after powering on the board. If you have an odd boot mode when you connect it may be impacting your ability to access the processors properly.

For some reason all of your images have dissapeared:

My DIP switches are:

Cout 0: 1

Cout 1: 0

Cout 2: 1

Cout 3: 1

Yout 4: 1

Yout 5: 1

Yout 6: 1

Yout 7: 1

Where 1 = ON which is the position nearest the writing 'Cout' or 'Yout' on the PCB.

Enum 0 and 1 are both in the H position.

Which is...erm wrong....isnt it 'bangs head against wall'

Sorry, couldnt see the wood for the trees.

Im still unsure why I couldnt connect to the DSP. If self booting, shouldnt I be able to connect without setting any registers as its essentially free running.

For some reason all of your images have dissapeared:

For some reason they are not showing up immediately in the post and I have to edit them in after, I can see them now on the forum but not in the email that goes out. I made a post in the moderator forum about this, hopefully it is something that the IT folks can fix.

As to the dip switch settings if you still cannot see the image in the above post they are starting with COUT1 "0000111110", how much this impacts I am not sure without digging into the settings, but for a quick test it should be easy to set the switches like mine.

Dear TI engineers ,

       I am using a Spectrum Digital Jacinto EVM , I met the following problems.

       When I connect the EVM to CCS, ARM can be connected and run , however the DSP can not .

      The error message is like this :

Error connecting to the target:

Error 0x80000244/-1137

Fatal Error during: Register, Initialization, OCS,

It appears that the target is being held in reset.  This may be

due to Wait-In-Reset (WIR) configuration set by the EMU0=0

and EMU1=1 pin settings.  If this is the case, DISCONNECT

all CONNECTED devices including icepick and then select

RETRY to clear the WIR configuration.

If this is a multi-core system, the master CPU may not be

releasing the DSP/MCU from reset.  Please check your

configuration in CC_setup and/or your GEL file to ensure that

nothing is blocking the DSP/MCU from being released from reset

Sequence ID: 0

Error Code: -1137

Error Class: 0x80000244

Board Name: DM6446_SDXDS560R

Cpu Name: C6400PLUS_0

Abort:              Close Code Composer Studio.

Retry:               Try to connect to the target again.

Cancel:             Remain disconnected from the target

Diagnostic:        Run diagnostic utility.

will you please tell me what 's the problem ?

Thanks a lot and hope for your reply .
