AM243x-EVM Debug (Error -1170 @ 0x0)

Hi Eli,

A couple of questions:

1. What version of the board do you have?  There should be a sticker near the LCD screen that says something like "PROC101C(005)" or similar.  Can you let me know what this says?

2. Have you gone through the EVM Setup as outlined on this page of the SDK Getting Started Guide?  https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html  Note that the page covers both the LP-AM243 and the AM243 EVM, so make sure you are following the steps for the EVM.

Thanks,
Mike

Hi Eli,

Could you please take a look at this page? https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds_target_connection_guide.html#buffered-case

The error (Error -1170 @ 0x0) is caused by the inability of the JTAG debugger to access the DAP or one of its ARM subcores. This is usually caused by either a hardware failure on the board or invalid code on the CPU core that causes it to reset itself continuously.

Hi Mike,

I'm using a completely new EVM .

The previous one I used wasn't lilting the LEDs as described in the PDF - so I ordered and now got a new one.

Near the LCD it says PROC101(005)

I've started with the BOOT MODE switches as in the PDF 11011111 00000000.

After powering up , I have all LEDs besides LED2 (I'm using AM243x) , lit.

I've pushed the test connection button and got result that all is ok.

Now I'm starting the debugger and after a short time get the 1170 error.

I'll try to follow the link you've added.

Thanks,

Eli 

Hi,

I've got the second link you've sent.

I'll try to follow.

Please explain the process and what is the DAP.

Thanks,

Eli

Hi,

I see on the CCS debugger setup MAIN_Cortex_R5_0_0

Could you please explain what does it mean , I'm I on the correct one ?

Thanks,

Eli

Hi,

Now I try with a simple "Hello world" example.

I read the recommended PDF's but no luck.   (error: 1170 no connection to target)

When I test the connection, I get:

But when I look at CCS Debug Configuration I get

Device Library source - no 'src' folder for AM2434-ALV.   

Is that a problem - What  should I do ?

Do I have to change port or something ?  

Thanks,

Eli

Hi,

On the CCS script console I see

Initializing .. (Completed)

js:> Connecting to DMSC_Cortex_M3_0!
Connecting to DMSC_Cortex_M3_0!
Connecting to DMSC_Cortex_M3_0!
Connecting to DMSC_Cortex_M3_0!

What is M3 ? 

Please HELP !

Thanks,

Eli

Hi Eli,

The JTAG test connection printout you provided shows the JTAG interface is working fine.  Note the lines that say the integrity tests succeeded.

With this, I strongly suspect that you have not completed the EVM Setup procedure as outlined in my first post:  https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html  Can you make sure you complete this procedure and get the expected printouts and messages to the terminal at the correct spots in the procedure?  If not, please provide details on where it is failing and any details you can about the setup you have.

Thanks,
Mike

Hi Mike ,

Thank you so much for helping me - I'm lost here !

I have CCS 12.4.0   with a new Sitara AM243x Evaluation Module PROC101C(005)

I've  set all the boot switches as in the PDF - to no boot 11000000 and 00000000

I've  connected the power supply to the board then plugged it to the wall AC power

I switched the SW1 on - then all LEDs went on , as in PDF.

I then connected the JTAG j28 connector to the board then to my PC - I saw the connection on PC's device manager as in PDF

I've tested connection from CCS button - all success !

I've loaded the "Hello World" example from the SDK (without any changes)

I've compiled the code then started the debugger.

After a while it says error 1170. 

Then I repeated the steps with an external XDS110 debugger connected to 20pin connector on the board.

Also error:1170.

I've tried without the *.gel files 

I've tried from the Debug  Icon

I've tried to launch from "Target Configurations" then connect target from the debugger

I've tried 1Mhz TCLK as in some PDFs 

I've tried xds110reset .exe -a toggle 

No luck - error: 1170

Is there something I'm missing here ?

Thanks,

Eli

Hi Mike,

I'm using a new EVM - Do I still  have to use Phyton-3 step with the UART - erasing FLASH ?

Which connection fails and makes error 1170 ?

Thanks,

Eli

Yes, you still need to do the python step shown here:

  cd ${SDK_INSTALL_PATH}/tools/boot
  python uart_uniflash.py -p COM<x> --cfg=sbl_prebuilt/am243x-evm/default_sbl_null.cfg

This is important as it initializes the SOC.  Failure to complete this step (and the rest of the procedure outlined in the EVM Setup page) will prevent you from being able to connect to the SoC via JTAG, exactly like what you are seeing.

One note, I know you said there was a sticker that said "PROC101(005)".  However, I believe there is a letter missing between the "101" and the "(005)".  It should read "PROC101C(005)".  Assuming this is the case, then you actually have an HSFS (High Security Field Securable) device, which needs a different config file to be run by uniflash in the python step.  Instead of the "default_sbl_null.cfg" file, you should specify the "default_sbl_null_hsfs.cfg" file.

Once you complete the board setup correctly, you will be able to connect to the device via jtag.

Thanks,
Mike

Hi Mike,

Thanks for your effort and clarification, I will try it.

What is the best way to debug using ion board XDS110 or external one or doesn't matter ?

Eli

Hi Eli,

There is no difference in performance between on board XDS110 and external.  I usually regard the onboard option as "easier" since you just need to connect a USB cable to it, but functionally, there is no difference.

Thanks,
Mike

Hi Mike,

Yes you are right my board is "PROC101C(005)" so I'm following the instructions - I type 

C:\ti\mcu_plus_sdk_am243x_08_06_00_43\tools\boot>python uart_uniflash.py -p COM7 --cfg=sbl_prebuilt/am243x-evm/default_sbl_nul_hsfs.cfg

then get error

[ERROR] Dependant modules not installed, use below pip command to install them. MAKE sure proxy for pip is setup if needed.

I type

C:\ti\mcu_plus_sdk_am243x_08_06_00_43\tools\boot>python -m pip install pyserial tqdm xmodem 

getting error:

C:\msys64\mingw64\bin\python.exe: No module named pip

I'm not familiar with python.

Please help.

Thanks,

Eli

Hello Eli,

What version of Python do you have?

Try using python –version.

If that doesn't work, try python3 –version instead.

Best Regards,

Ralph Jacobi

Hi Ralph,

python --version  says Python 3.10.12

What does it mean "Dependant modules not installed"

it asks for         python -m pip install pyserial tqdm xmodem

How do I install it ?

I've never used python before.

Thanks,

Eli

Hello Eli,

Frankly I am not sure and I'm confused that pip isn't installed. It's supposed to be installed by default with Python 3.4 and newer.

Our instructions on Python installation and verification are here: https://dev.ti.com/tirex/content/mcu_plus_sdk_am263x_08_06_00_34/docs/api_guide_am263x/SDK_DOWNLOAD_PAGE.html#INSTALL_PYTHON3

If pip really isn't installed, you should try and re-install python. Beyond that, you will need to search for a solution, I don't know how to install pip from python because I've never had to do that and none of our other users ran into this issue.

Best Regards,

Ralph Jacobi

Hi Ralph,

I installed new python 3.11.4

C:\ti\mcu_plus_sdk_am243x_08_06_00_43\tools\boot>python uart_uniflash.py -p COM7 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null_hsfs.cfg
[ERROR] Dependant modules not installed, use below pip command to install them. MAKE sure proxy for pip is setup if needed.

python -m pip install pyserial tqdm xmodem --proxy={http://your proxy server:port or leave blank if no proxy}

Which python should I use ?

Is there a way around to get my EVM going ?

Thanks,

Eli

Hello Eli,

Have you tried

python -m pip install pyserial tqdm xmodem 

If so what result did you get?

Best Regards,

Ralph Jacobi

Hi Ralph,

Yes I did.

It installed the missing python packages.

Now I can run - python uart_uniflash.py -p COM7 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg

Mike suggested I run default_sbl_null_hsfs.cfg but in AM243x SDK ther's no such option only default_sbl_null.cfg

Were can I get the default_sbl_null_hsfs.cfg for AM243x ?

Please advice.

Thanks,

Eli

Hi Eli,

Glad you were able to get your board working.  If you run into any more issues, please feel free to open a new E2E post as neede.

Thanks,
Mike
