I have bought 5 identical products : FRDM-KW38
I have followed user guide as defined in NXP Video: https://www.nxp.com/document/guide/getting-started-with-the-frdm-kw38:GS-FRDM-KW38
I have imported the NXP SDK example shown in this video frdmkw38_heart_rate_sensor_freertos
After clean, build and launch debug, the FRDM-KW38 is in a bugged state : The firmware has been loaded into the board but I cannot reload again the same firmware. When I want to launch debug, I have a pop-up indicating:
Unable to connect wire for probe index 1.
Error: Wire Ack Fault - target connected?
I have taken another board and after the same usage , I have again the same error. How to restart my FRDM-KW38 and loaded correctly another example or remove this error ?
Thanks in advance for your help.
The NXP link is incorrect to Download – OpenSDA Bootloader and Application
In this page : https://www.nxp.com/design/microcontrollers-developer-resources/ides-for-kinetis-mcus/opensda-serial...
the link is for a FRDM-KW36 (not for FRDM-KW38)
On this page, use only Segger Jlink FRDM-KW38 to perform a debug session
I have rebooted my computer (under Windows 10)
I have cleanup the debug
I have deleted the frdmkw38_heart_rate_sensor_freertos project and reload it again
Clean is Ok
Build in debug mode is OK
BUT Impossible to debug again....
I have selected the DAPLink CMSIS-DAP
Then whatever the action => here I have choice : check files areas blank
The result is :
