MIMXRT1170-EVK bricked

daniJVV — Tue, 04 Apr 2023 14:36:02 GMT

I've been using this board for a month, but trying a new software it got bricked.

When I try to upload a working project this is the result:

I readed about MCU boot utility, but when I try access to the board the USB is not found, and shows this error:

Then I put the board in Serial downloader and I can upload the firmware, but this is not working.

With the Serial downloader and MCU boot utility I have this message:

I need to unlock this to continue working. Does anyone knows what is happening?

Thank you in advance.

Could you please change the MCU Device in MCU Boot Utility to i.MXRT117x and try again?

Let us know if you have another issue.

Hello @RaRo

I got this message when I tried to connect with USB:

With UART I can connect, but I don't know which parameters to look at.
Is there something to check in any memory (boot image, eFuse...)?

Thank you for your help.

I tried to debug a touch screen example that was working before this problem, and now there is no errors when uploading the firmware.

But the problem with USB-HID MCU Boot Utility continues.

Could you please try with the following steps?

First, move your SW1 to 0001 (Serial Downloader mode).
Secondly, place a jumper in position 5-6 in J38 to power the board trough J11.
Then, connect both J11 and J20 to your computer and open the NXP MCU Boot Utility.
After that, select the i.MXRT117x as your MCU Device.
Connect to ROM trough UART.
Then, check now if is detecting your USB-HID connection. Turn off the board and change the position of the jumper in J38 to position 3-4.
Finally, power up the board again only through J20, and check if your board is being detected.
