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.
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.
Hello @daniJVV,
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.
