debug error

[vinaymanikkoth]

modified the imxrt 1060 evk board to test HyperRam. debug fails with following messages after that.

tried running a known project as well. right now board has hyperRam mounted. 

[vinaymanikkoth]

yes, not able to program at all. looks like main CPU is not responding to anything. attached the full screenshot of boot utility. let me know if this is not what you asked 

no vendor shows up when usb connected to J9. 

any suggestions to debug U1.

Hi vinaymanikkoth,

   What's your selection in the below now?

OPTION1: USE Hyperflash( DNP R153~R158, Mount R356,R361~R366)
OPTION2: USE QSPI FLASH(Mount R153~R158, DNP R356,R361~R366)

   MIMXRT1060-EVK is using the QSPI option2 in default, do you already modify it?

   If you already modify option2 to option1, please modify back to option2, then try to connect with the QSPI flash, any progress or not?

  BTW, do you have external JLINK or not?

  If yes, you can use the external JLINK and the JLINK commander to connect your board, can you find the ARM core or not?

Best Regards,

Kerry

[vinaymanikkoth]

nothing changed. 

is there any way to verify MCU is powering-up properly ?

can i get the sample device so that i can try to replace the MCU ?

[kerryzhou]

Hi vinaymanikkoth

  I have told you, you use the external JLINK to check your chip with the JLINK commander through the JTAG interface, whether the ARM core can be found or not.

Eg:

Please check it at first.

Best Regards,

Kerry

[vinaymanikkoth]

i dont have a JLINK. i tried to do the same using ULINK2. attached the screenshot of error. 

[kerryzhou]

Hi vinaymanikkoth

  Do you have the NXP LPC-LINK2? That tool also can used as the JLINK.

  BTW, you need to use the SWD interface, not the JTAG, the RT chip in default using the SWD interface.

Best Regards,

Kerry

Hi vinaymanikkoth，

  Do you refer to the AN12239 application note about How to Enable HyperRAM with i.MX RT?

https://www.nxp.com/docs/en/nxp/application-notes/AN12239.pdf

The software project is:

https://www.nxp.com/docs/en/nxp/application-notes-software/AN12239SW.zip

Do you use the same hyperRAM as this application note?

Do you use this project directly, and debug it? If you are using the RT1060, this project should works OK on your board directly.

Wish it helps you!

Any updated information, please kindly let me know.
