IMXRT685-AUD-EVK debugging issue with JLink

[e_matthews]

it is the first time i use IMXRT685-AUD-EVK, i meet two issues blocking in setup stage by following the Tutorial steps.

First Issue:

when debugging the example, error message popups as followng snapshot:

Spoiler

the logs from output is captured in attached text file: MCUxpresso_err.txt

The environment and versions of IDE is as following list:

MCUXpressoIDE: 24.9.25

JLink: V810 (installed with MCUXpressoIDE)

Windows 10 Pro x64 22H2

Second Issue:

failed when use xt-ocd to connect EVB through JLink, "Error: SWD Wait time-out expired!" printed.

the template topology.xml is from here , and the modified version (with my serial number) is in attached

whole log is as following:

Ubuntu 22.04:

Have tried different combination with OS, xtensa ocd versions and JLink versions:

Win10, Win11 and Ubuntu 22.04

xtensa ocd version: 14.07, 14.08, 14.11

JLink version: V810, V810C, V696(in another topic, this version fixed similar error, but not mine)

Also checked the jumps as default:

Dear @e_matthews ,

Thank you for your interest in the NXP MIMXRT product, I would  like to provide service for you.

Please tell me your SDK information, It must be consistent to your Board.

From image you post I know your board is MIMXRT685-AUD EVK board , so you should import MIMXRT685-AUD-EVK SDK, not MIMXRT685-EVK SDK, It is very import.

Also, I suggest you can refer to this link

https://www.nxp.com/document/guide/getting-started-with-imxrt685-aud-evk-development-platform:GS-MIM...

Wish it helps you.
If you still have question about it, please kindly let me know.

Best Regards

Dear @mayliu,

Thank you for your kindly advice, I will follow your guide to check the toturial from the correct link.

On the other hand, I double checked the wrong link that I jumped in:

https://www.nxp.com.cn/document/guide/getting-started-with-imxrt685-aud-evk-development-platform:GS-... 

the only difference between two links: mine is "www.nxp.com.cn" and the video content in the first section are different:

And then checking for the SDK version, what i used was for MIMXRT685-AUD-EVK as following:

I also rebuild the SDK from the new link. The new downloaded SDK package are identical with my old one:

Thank you again for replying! But there is still issue No.2 blocking, and it is not related with SDK. Only Jlink and xt-ocd are involved.

Dear @e_matthews ,

I use MIMXRT685-EVK debug, It is similar to  MIMXRT685-AUD-EVK.

1: Please make sure that modify usbser ID in  topology.xml file according to your JLINK.

2: the command is xt-ocd.exe -c topology.xml,  but I see your command is xt-ocd.exe -c .\topology.xml.  

Wish it helps you.
If you still have question about it, please kindly let me know.

Best Regards

Thanks! @mayliu

For 1, the "./" means the current path, just inditate where's the topology exist. It should be the same if without it.

For 2, i double checked the usbser ID which I used, it was correct and was retrieved from JLink log print as tortuial: 722949484

if I typed the wrong ID, the log was like the following instead of what i've got:

Hi @e_matthews ，

Hi, I have consulted with a RT600 series expert. He give some advices.

1: Please pay attention to the "Getting Started with Xplorer for EVK-MIMXRT685".

The path of the "Getting Started with Xplorer for EVK-MIMXRT685" file is in XXX\SDK_2_16_000_EVK-MIMXRT685\docs.

Especially, check  chapter 2.6 "2.6 Program LPC-Link2 with SEGGER J-Link", and update JLINK firmware.

2: Try to use J-link-commander to connect the board, whether It can connected.

3: Try to use MCUXpresso IDE create a simple project "mimxrt685audevk_hello_world" , using JLINK to debug, whether the project can run normally.

Wish it helps you.
If you still have question about it, please kindly let me know.

Best Regards

Dear @mayliu1 

Thank you for advices.

For 1, JLink firmware is updated with guide, log as:

For 2, JLink commander connection is verified:

For 3, hello world example from SDK is well debugging through JLink:

Does it mean JLink connecting to CPU is OK on IDE?

But JLink connection from xt-ocd still doen't work, it always show "Error: SWD Wait time-out expired!". Does it mean DSP still not work?

Best Regards!

Hi @e_matthews ,

Hi , I 'm glade that your project " hello world example" from SDK is well debugging through JLink.

Question1: Does it mean JLink connecting to CPU is OK on IDE?

Answer: Yes,  If you can debugging, It means CPU is OK on IDE.

Question2: But JLink connection from xt-ocd still doen't work, it always show "Error: SWD Wait time-out expired!". Does it mean DSP still not work?

Answer:  To reduce power consumption, The DSP core will do not power on  when the RT600 boots. If you want debug a DSP code, the RT600 Arm kernel need execute some code .

For the detail description, you can refer to the guide sheet.

Wish it helps you.
If you still have question about it, please kindly let me know.
If your question is solved, please tell me to close this case, thanks.

Best Regards

Thanks! @mayliu1 

It can work after i upload a hello world demo with DSP enabled through IDE (mimxrt685audevk_dsp_hello_world_usart_cm33)

The xt-ocd can connect to DSP now.

So I guess that because i bought a new board which was burned with the factory default image (without DSP enabled), but I want to debug DSP directly and ignore running IDE demo in toturial video, then it causes the communication failure.

Just an advice to add a tip in guide document that to run hello world with DSP first then to try debugging DSP.

Thank you again for your kindly support and your time! That's really helpful to me.
