TMS320F28335: What part of the target configuration should I modify to test 'Wait-in-Reset Emulation Mode' feature?

TMS320F28335: Wait In Reset Mode Failure

Part Number: TMS320F28335
Other Parts Discussed in Thread: TMDSEMU200-U

Hello there,

 

I am using the TMS320F28335.

 

I have finished developing the firmware and activated the CSM, to connect controller, if I change the boot mode of the chip to 'Branch to check boot mode' everything is fine. However, i have to use the "wait in reset mode".

 

I cannot access the JTAG emulator with "wait in reset mode".

 

I do some changes in the target configuration file, advanced settings, The JTAG nTRST Boot-Mode and nothing changed.

 

I think i can't change the emu0 and emu1 pins status. 

 

When I check the card's schematic, the EMU0 and EMU1 pins seem to reach the JTAG connection.

    Hi Halit,

    Currently, what are your EMU0 and EMU1 pins configured to be?

    Kind regards,

    Dear Favela, 

    As stated in Table 7.2 of the spru430F document, the JTAG n TRST Boot-Mode is set with EMU1 high and EMU0 low. I tried other options too, but nothing changed. I tried to upload image but the system gave an error.

    Hi Halit,

    I have brought this to the attention of the CSM expert, as I believe that is what is preventing you from accessing the JTAG emulator while in wait in reset mode. 

    Additionally, please note that due to the holidays there might be a delay in responses.

    Kind regards,

    Yes, EMU0 and EMU1 are pinned out to JTAG debug probe.

    What are you setting in the target configuration file? Can you please confirm with a scope that TRSTn/EMU0/EMU1 are being properly set by CCS? 

    Best,

    Dear Matt, Hello,

    As a debugger, I was able to activate the "wait in reset" mode using the xds560v2 System Trace. I did this with the same configuration and the same ccs11.2 software.

    Then I reinstalled ccs11.2 on another computer from TI's own website and tried again, but still couldn't get it into the "wait in reset" mode with the xds200 debugger.

    Best Regards,

    Hello,

    To make sure we're on the same page:

    • XDS560v2 works on CCS 11.2 with PC #1
    • XDS200 does NOT work on CCS 11.2 with PC #2

    Have you checked if the XDS560v2 works on PC #2? Does the XDS200 work on PC #1?

    Best,
    Matt

    Dear Matt,

    Let me clarify situation,

    • XDS560v2 works on CCS 11.2 with PC #1 and PC #2 with the "wait in reset" mode feature. 
    • XDS200 work on CCS 11.2 with PC #1 and PC #2. If CSM is not active, the program can be loaded. XDS200 does NOT work on CCS 11.2 with PC #1 and PC #2 with the "wait in reset" mode feature.

    Best Regards,

    Are you doing this by setting the properties like the below for XDS560v2?

    Hi Ki,
    Actually, I configure the XDS560 debugger as follows and can actively use the wait-in-reset mode.

    The JTAG NTRST Boot-Mode   --> Enabled - EMU1 is high, EMU0 is low,

    The Power-On-Reset Boot Mode  ---> Disabled - Both EMU pins remain hi - z 

    When I do the same configuration with xds200, "wait in reset mode" doesn't work, that's the problem.

    Ah I see. With XDS560v2, you see the EMU 0/1 pins in correct state as specified while with XDS200, it is not.

    Please note that you are using a very old and unsupported version of CCS. Could you try the latest CCS version to see if the same issue exists?

    Thanks
