Have you try to load the gel file, then connect to A8, connect to DSP before you try to download the hello world?

Hi Viet Dinh,

Thanks so much for responding.  I appreciate it very much.

So I think there's something very fundamental I'm missing.  I have the gel file specified in the target configuration, but before I can run it (if I'm running the debug process) the connection fails.  Is there another way to load gel files?  Perhaps through the scripting console or some such?

Also, can you confirm the proper gel file to load first?  

Sorry for the noob questions.  All the documentation on gel files I can find refer to CCS 4.2 and below.  If there's newer documentation, please point me to it and I promise I won't bother you (as much :) ).

Thanks,

O..

Orion,

Could you visit this page to see if it solve your problem?

Hi Viet,

I have previously visited that page.  Here is where I have the problem.

Snipped from page

Procedure to connect to the DSP on C6A8168/DM8148/C6A8148/DM8148 is described below:

1. After starting CCSv4 or CCSv5, create new target configuration. Select XDS510USB/XDS560USB emulator and device as TI816X/TI4X based on what is applicable.

Note:

• Select TI816X for C6A8168 and DM8168
• Select TI814X for C6A8148 and DM8148

2. Launch debug session with this configuration. Once you see the emulator connection. You can connect to the cortex-A8.

/SNIP

When trying to do these 2 steps, I run into two problems.

The first, which I think is minor, is that the JTAG which ships with the EVM is a XDS100v2, so I select that option instead

The second, which I think is major is, In CCS5.1 I can't figure out how to connect without using a debug session.  When I debug, before I can run any gel scripts, it errors out saying "device is in reset..." and terminates the debug session.

So I got the idea to try and build an arm hello world project first since it seems the arm sits on top of the DSP.  I figure if I can make a connection there, then I can run the gel scripts and be on my way.  So I create a new CCS project,  Can't find the DM148 or DM14x partnumber under ARM, so I select a generic A8 device.  It builds its own "hello_world" fine.  It also connects and downloads fine, but verifies incorrectly.  I imagine that's because there's no appropriate address-map setup for this device as I just used a generic A8 device.

So two ways I can see to proceed are.

1) please tell me how I can connect to the ARM without needing to use a debug-session for it

2) please tell me where I can get proper A8 device support for the DM8148 part.

3) Tell me why I've completely missed the boat here. :)

Orion,

Let back up.  First of all, have you create a New target config file?  If not, from CCS, go to File->New->Target Config File.  Choose file, dir then click on Ok.  Once you done that, the <config>.ccxml should be open.  Choose your Jtag connection from the pulldown, type in ti814x in Board or Device option and click on save.  Once you done that, go to Run->Debug Configuration and select the .ccxml file you just created and click on apply and then debug. 

After that, you should see all the processors in the device.  You now can connect to processor, load the gel file and run.

Hope it helps,

Viet

HI Viet,

Ok, we're making progress.  Thanks for your help and your patience.

I have done as you suggested.  Then I select the Cortex A8 and right-click -> connect.

Then I select Tools/Gel Files and get the Gel File View.  I right-click in the Gel file View and select "open".  

Now the question is which gel file to use.

The most obvious choices are

.../Baseboard/src/CCS_Test_code/Base_Board/Integrated_Baseboard_Tests/GEL/DM814X_1_0.gel

and

../Baseboard/src/CCS_Test_code/Base_Board/Integrated_Baseboard_Tests/GEL/DM814X_2_x.gel

2_x.gel 

DM814X_1_0.gel running DM814X System Initialization/DM814X_System_Initialisation_GP_device ends up in an infinite loop around the PLLs

The last line from the console is

CortexA8: Output: DM814X USB_PLL Init is in Progress, Please wait ..... 

In reading the gel file there are a bunch of while (xxx) != yyy;

I imagine it's stuck in one of those loops.  Perhaps a timeout would help here.

If I reset the whole system and try DM814X_2_x.gel, I get to:

CortexA8: Output: **** DM814X ALL ADPLL INIT IS COMPLETE *******
CortexA8: Trouble Writing Memory Block at 0x48100100 on Page 0 of Length 0x4: (Error -1065 @ 0x3D5A) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.569.0)
DM814X_System_Initialisation_GP_device() cannot be evaluated.

at PLL_CLOCKS_Config() [DM814X_2_x.gel:885]
at DM814X_System_Initialisation_GP_device()

Relevant part of the gel file is here:

GEL_TextOut("\t **** DM814X ALL ADPLL INIT IS COMPLETE ******* \n","Output",1,1,1);
WR_MEM_32(0x48100100, 0x01031FFF);
WR_MEM_32(0x48100114, 0xC010E);
WR_MEM_32(0x48100118, 0xF);

Thanks in advance for any advice you might have.

Orion,

Please try to use the Gel file from here:  http://e2e.ti.com/support/embedded/bios/f/355/t/153410.aspx#555839.

This just happened automatically upon connecting to the ARM.  It must have run OnTargetConnect.  I didn't do anything else at this point.

Then I try to download hello_world and get 2 pop up errors which say

An error has occurred. See error log for more details.
The function "getGelFiles" returned an error condition (0x80780001)

AND

Load Failed

which seems to be related to the console error:

C674X_0: Trouble Writing Memory Block at 0x20 on Page 0 of Length 0x5a00: (Error -1190 @ 0x20) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.569.0) 

C674X_0: GEL: File: C:\Users\Orion\Dropbox\BRE\TICode\hello_world_on_board_2\Debug\hello_world_on_board_2.out: Load failed.

This seems similar to the other page you referenced.  However I think it's different because this write error occurs on the C674X whereas the other example failed on the Coretex.

Instead, I think I may have setup my project incorrectly.  The only Device I've selected is TI8148, but I don't see where it specifies in the project where to write/execute code.

Thanks,

O..

Ok, now I'm a bit farther. I got the simple sys/bios example to execute on the target, but it instantly runs to its abort() routine at 0x80009a00" .

One thing worthy of note is that if I select a device of DM8148, then the RTSC page won't let me specify the platform, but if I select "Generic C674 device" Then it lets me select a platform of

ti.platforms.evmDM8148

and a target of 

ti.targets.C674

However, if I choose a device of 

DM8148

Then no targets or platforms are displayed in the RTSC page.

Could I have a corrupt DM8148.xml file?

Thanks for your help,

O..

Orion,

Glad you got alot closer.  :)

Have you try to connect the DSP before you try to download the file?

BR,

Viet

The program is running on the board, its just not getting very far before it gets stuck in the weeds.  i.e. before main can run.

I've been poking at the board a bit more and have come to the realization that sysmin is being written too before abort() is called.

sysmin buffer contains:

{module#43}: line 1041: error {id:0xc2c0000, args:[0x8000, 0x19e6d2f]}

xdc.runtime.Error.raise: terminating execution

I can't find any references to this while searching the forum. 

Thanks for any advice.
