K32W041 - read configuration from memory dump

hres — Fri, 21 Feb 2025 15:01:21 GMT

I have a board with integrated K32W041 chip but I don't know how it's configured. Communication is possible via UART. Is it possible to read the pin and clock configuration from memory dumps made with dk6prog?

Regards,

Are you working with a development kit? Or is it a custom board?

Can you comment on what application did you flashed on the chip?

Regards

Luis

This is a custom board. Currently there is a firmware that allows to configure it from phone on first start.

I would like to prepare firmware with Thread support and run Thread Boarder Router.

Info from dk6prog:

For testing Thread examples and more information about commands please refer to NXP Github

Thank you for your answer. I know that there are examples of how to prepare the appropriate firmware with support for Thread.

I wonder if it is possible to read the current configuration(pins, clocks), for example, using MCUXpresso?
The problem is that the system is connected directly to the SoC, but I don't know, for example, which GPIOs were used.

Hi
No, it's not possible to read, The GPIOs/CLK should be declared in the programming code.

Best Regards

Thank you for your answer. I'm afraid that if I use the firmware from the example I will lose contact with the chip.

Are there sources for the "NXP K32W Device Programmer" application available somewhere?
