MIMXRT685-EVK

[ray_deng1]

Dears,

I use NXP LPCScrypt to program MIMXRT685-EVK to JLINK debug probe, but it runs error, and cannot change to JLINK probe. CMSIS-DAP is OK to program. You can check the below log and advice.

Hello Ray, 

At the end of the log that you shared the following information is shown: 

Programming LPCXpresso V2/V3 with "Firmware_JLink_LPCXpressoV2_20190404.bin"

LPCXpresso V2/V3 programmed successfully:

So it seems that the programming of the firmware was successful. Besides, I made several tests on my side and I didn't face any problems while programming the JLink firmware. I used version 2.1.1_15 of the LPCScrypt software. If you try to debug a project on MCUXpresso IDE, does the IDE recognizes the on-board debugger with the JLink firmware?

Hi Victor,

   Thanks for your kindly help,

   Acutually, I can program CMISS-DAP successfully while JLINK not. After program JLINK, open JP1 connector, reboot EVK, it is cannot find JLIN VCOM in Computor Device Manger Tree. MCUXpresso also cannot recognize.

  I have tried LPCScrypt_2.1.1_15, LPCScrypt_installer_2.1.0_842 in 2 Win x64 PC, still cannot work.

Thanks &BRs,

Ray

Hi Ray, 

Thanks for the additional information. Could you please share a screenshot of the result when you run the program_JLINK script? For example: 

Additional to this, MCUXpresso IDE needs SEGGER J-Link software version 6.62c or newer for compatibility with the RT600-EVK. MCUXpresso IDE may ship with an older version, which can be changed within the MCUXpresso IDE preferences. Go to Window > Preferences > MCUXpresso IDE > Debug Options > J-Link Options. 

If you have an older version of JLink you can download the newest version available from the following link: https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack

Hi Victor,

I tried another EVK from my colleague, it is show the same log, and it works well. Below is the log,

Would you please kindly help to advice?

Hi Ray, 

Just to be sure that I understood you correctly. Programming the JLink firmware does work on your colleague's board but not in yours, is this correct? The log that you attached corresponds to your colleague's board or your board?

In the case of your board, you mentioned that it doesn't work, but could you please clarify this? For example, if you go to MCUXpresso IDE and you click the debug option, does the IDE recognizes the on-board debugger?

Regards, 

Victor

Hi Voctor,

Thanks for your patiently support.

My EVK cannot recognized by MCUXpresso while my colleagues can.

Is the LPCLINK2USB firmware broken?

Thanks &BRs,

Ray

[victorjimenez]

Hi Ray, 

Yes, it seems that there's a problem with the on-board debugger of your board. To know for sure if this is the problem, could you help me to do the following tests?

• MCUXpresso doesn't recognize your board, but, does your PC recognized the board? For example, in my case, if I go to the Device Manager I can see the board under Ports.

• If you change the firmware to CMSIS-DAP instead of Jlink, does MCUXpresso recognizes the board?
• If the CMSIS firmware doesn't work, do you have an external debugger on hand? This way you can bypass the on-board debugger and connect directly to the RT685. If you are able to program the RT with the external debugger then we can be sure that the RT is not damaged.

Regards, 

Victor

Dear Victor,

I use external Multilink for debugging, MCUXpresso can recognize the debugger, but cannot link target, maybe MCU RT685 broken.

Thanks &BRs,

Ray

[victorjimenez]

Hello Ray, 

Just to confirm, did you connect the external debugger to your evaluation kit through J19? Also, did you apply external power to your EVK through J6?

You mentioned that you have two boards with you and that you were able to work with one without problems. Just to discard that a misplaced jumper is causing this behavior, could you please compare the jumper settings o both boards?

Regards, 

Victor
