NXP ROM in open mode, Can not program Teensey 4.1

c172jeff — Sun, 26 Sep 2021 13:55:36 GMT

Help. This might not be the most ideal place to post this question. I am stuck and need direction.

I bought a Teensey 4.1 board and programmed it a few times. This board is similar to an Arduino but based on a fast chip with tons of features. I guess it is an NXP chip.

I set it aside for a few months and am now looking to reprogram it. I cannot. It seems there is communication to the board but the board throws an error to the loader about NXP Memory

"23:31:18.259 (loader): Opps, NXP ROM in open mode, but we do not yet have code for this case "

I tried two known working USB cables am quite sure that there is communication. I don't think it is a Windows 10 thing. I am running Windows 10.

Can anyone on this forum provide some advice and offer suggestions? I hate to buy a new $40 board when it seems flimsey enough that the ROM gets stuck in open mode. What is ROM? I know it is read only memory, but is this the flash memory that the loader is trying to program?

If so, is there a way that I can close it with an external circuit/connection and/or better code/tools?

I would like to use this Teensey, just that I have a problem throwing money at something that seems likely to repeat. I treated this board nice.

Here is the log from the Teensey loader . The loader asked to press a button, then it displayed the second section with the line of output above. The button press on the Teensey triggered action on the loader.

Hi @c172jeff ,

I haven't Teensey4.1. I'm not sure what's the problem. RT1062 ROM code hasn't open mode.

In https://www.pjrc.com/store/teensy41.html, I see that this board has a dedicated bootloader chip. And there is a Program pushbutton. Pressing the button button puts Teensy into programming mode. Can this work on your board? And Teensy 4.1 will fully erase its non-volatile memory and return the flash memory to a simple LED blink program if the program button is held between 13 to 17 seconds. If you can fully erase flash and power on again, Teensy Loader should can program the board.

Regards,

Jing
