FRDM-KW38 Linkserver program issue

[Adam_Ho]

Hi, 

I am using FRDM-KW38,

MCUXpresso IDE v11.8.0.

Press reset button before connected USB port to PC.

After connected to PC, KW38 is in "DAPLINKBOOT",

Paste download file.bin from "https://www.nxp.com/design/design-center/software/sensor-toolbox/opensda-serial-and-debug-adapter:OP..."

Now, I Debug with LinkServer probes,

The window always show "SWD Configuration" 0 available SWD Devices detected.
Connect a device and try again.

Please help me to debug kw38.

Thanks.

Hi Ricardo, 

Is "Delete launch configurations"  mean "clean up debug"?

I have tried, but still not work.

The last SDK example is "frdmkw38_adv_ext_peripheral_bm".

Thanks,

Hi Adam,

Please delete these files:

Are you able to flash any other SDK example?

Please let me know your findings.

Hi Ricardo,

1. I have deleted these file and "Debug using LinkServer probes".

2. The same error occured.

Do you have any other idea?

Thanks,

Hello Adam,

Your FRDM might be in Low Power mode. Could you try to do a mass-erase? By using an "unlock kinetis" command in J-Link Commander, or a mass erase command through MCUXpresso, which works as well.

And the Low-Power mode can be disabled by setting the following macro (in the app_preinclude.h header file) to a 0, like so:

/* Enable/Disable PowerDown functionality in PwrLib */
#define cPWR_UsePowerDownMode           0‍‍‍‍

If this is not working, I would try with an external debugger.  

Hope this helps.

Regards,

Ricardo

Hi Ricardo, 

I use MCUXpresso to do mass erase.

but there is "Target Connection Fail" show in console log. 

 I attach the erase log on below.

Could you find any clue on development board?

Thanks for support.

Hi Adam,

Could you please try using Jlink?

If not, I would recommend checking with an external debugger.

Hello,

Hope you are doing well. Could you please try deleting the launch configurations of the project?

Which was the last SDK example that was running on the board?

Ricardo
