Failed when assert(serialHandle);

alan5 — Mon, 13 Apr 2020 01:36:40 GMT

Hi I am working on LPCXpresso54608. I am running on an example to control LED in the shell. But there is an error when assert(serialHandle); with the error message captured

ASSERT ERROR " .fsl_shell.c:820 : serialHandle

The code that I am using is generated by MCUXpresso.

Thank You!

Hi Alan,

Could you please share the detailed process you are following so I can replicate this issue on my side?

Best regards,

Felipe

Also getting same problem running frdmkl27z_shell example project straight out the box from the frdm_kl27z demo examples.

The example is being run in the default DEBUG configuration.

The other semihosting example called frdmkl27z_hello_world works perfectly.

The Assert fails because SerialHandle is null.

If Alan found a fix I would be interested to know what it is.

I don't have a solution yet. I am not using that feature. Just that when I generate the example, I saw this issue. I had proceeded with other tests.

Hi Alan,

I checked the example on my side using my LPCXpresso54608 board and it worked as expected. Please check the below image.

I used MCUXpresso 11.1.1 and SDK 2.7.0 to test it.

Best regards,

Felipe

Hi Alan,

The solution is to ensure that;

SDK Import Wizard -> SDK Debug Console = UART (not Semihost! The default)

as shown below.

(Also you need to give the second attempt at importing this project a suffix so that the [Next] and [Finish] buttons are ungreyed - allowing you to proceed.)

The imported project settings do NOT control the "SDK Debug Console" setting. You have to set it manually.

Regards, and Thank you Felipe,
