Can't flash or full erase i.MXRT1050

[maulesh]

Hello,

Facing the issue in my i.MXRT1050 kit, cannot program kit using MCU Xpresso as well as drag-drop method. Previously it was working well. 

 https://community.nxp.com/t5/i-MX-Processors/IMXRT1050-EVKB-can-t-flash-anymore/m-p/1461180 

Tried above given all methods to connect MCUBootUtility using HID device. But couldn't find HID device in MCUBootUtility. 

• Tried with J28 power supply and connect other USB cable to J9 but device didn't detect.
• Tried J1 from 5-6 to 3-4 and connect one USB cable to J9 only but still not detectable.

Switch 7 position: 1-OFF, 2-ON, 3-OFF, 4-ON

 

Is there anything that missing out from my side? or any other method to mass erase chipset?

Please look into it and help me out.

Thanks in advance

Hello @maulesh,

It seems your method is correct, so it could be useful to try with something different:

• Have you tried to do a mass erase trough MCUXpresso IDE GUI Flash Tool? Look at the following community post: Managed to "brick" your i.MX RT1010 EVK? - NXP Community
• Also, it might be useful to try with MCUXpresso Secure Provisioning Tool. You can download it here: MCUXpresso Secure Provisioning Tool | NXP Semiconductors. There you could test your connection with your board trough USB or UART and try to write an image in your board.

Best regards, Raul.

Hi @RaRo,

Thanks for the reply.

I have tried both solutions, but neither worked. I couldn't perform a mass erase using the GUI flash tool, and the processor is not detected over UART or USB when using the MCUXpresso Secure Provisioning Tool.

Hello @maulesh,

Could you please check if your computer detects the USB connection with your board? Please check the Device Manager for that.

[Ports in Device Manager]

Also, if it's possible, could you please try the USB connection with another computer? Is the behavior still happening? This is because some of the USB drivers of the computer might have stopped working.

Best regards, Raul.

Hi @RaRo ,

I've checked the device manager ports as below.

When I connect the board to the connecter J28, I'm able to see the port (COM4) but I think it is failed make connection to the MCU. 

I've another working same board which is working fine which I've tested connection in MCUXpresso Secure Provisioning Tool both serial (J28) as well as USB(J9).

Few observations (in not working board):

• When I press the Reset button (SW4) or System reset POR (SW3) nothing happens to the board even Reset LED (D15) not blinks.
• While drag and drop any binary (LED blinky) to the drive RT1050-EVK, LED D16 blinks and generate the FAIL.txt file with message "The interface firmware FAILED to reset/halt the target MCU".
• USB (J9) also not working.

Thanks.

Hello @maulesh,

Could you please give us more background of what you were doing before the board started with these problems?

Also, could you please measure the voltage signal DCDC_3V3 (test point: TP7) which is the voltage that goes to D15 in your EVK?

Finally, could you please try the following methods with your board?

• SDIO method: Tutorial: Booting the NXP i.MX RT from Micro SD Card | MCU on Eclipse; Using SDIO with SDHC in the i.MX Applications Processors.
• blhost method: How to Enable Recovery Boot from QSPI Flash; MCUBLHOSTUG.

Best regards, Raul.
