K32W041 - Unnable do debug and SDK bug

[adrian_chmiel]

Hi,

I started working with K32W041 and at the beginning I found bug in SDK.

When I create new project for K32W041, MCUxpresso incorrectly generates files and you cannot use e.g. Pin Tools or Clock Tools (there are inform, that MCu is not selected). Also, don't add files board_utility.c/.h in "board" catalog, it's not exist.

For K32W061 everything is ok. Since these are the same processors (only *041 has no NFC) I currently use the SDK for K32W061.

Second thing, there is some problem with debug, sometimes MCU is stuck and I cannot debug any more. In console I see:

And at this moment I don't know how too fix it. I use custom board, not eval board, with LPC-Link

Hi @adrian_chmiel,

I hope you are doing great.

When I create new project for K32W041, MCUxpresso incorrectly generates files and you cannot use e.g. Pin Tools or Clock Tools (there are inform, that MCU is not selected). Also, don't add files board_utility.c/.h in "board" catalog, it's not exist.

The wireless examples are not compatible with the Pin and Clock Tools, you could change your configuration and after that, you could copy them into your code.

Now, what are the MCU settings that you have?

Did you try with a hello world example?

Regards,

Mario

Hi Mario,

Examples and "New project..." button work correctly but only for k32W061.

For K32W041 there are no examples and "New project..." generate incorrect project.

For example:

New project... -> K32W041 -> default settings

and Finish.

When I try build:

And when I try open Pins or clock perspective:

The same procedure for K32W061 works fine.

MCUXpresso IDE v11.2.1 [Build 4149] [2020-10-07]

SDK for K32W 2.6.2

Hi Adrian,

I hope you are doing great. I recommend selecting the UART interface instead of semihost as the debug interface.

You can try to add the board_utility.c and board_utility.h to the "board" folder. The new Application is not released now, but we will release it later.

Regards,

Mario

Hi,

I doesn't have free fins for USART interface, but problem was with debuging not only with checking register but completely in communication programmer <-> MCU (debugger cannod connect to MCU).

When I use JLINK problem is gone, but still exist if we use LPClink.

Additional information:

When I use LPC-Link as a J-Link, debugging work correct.
