Wrong LED ports specified in SDK's build.h

Was I given access to the wrong board in MCUXpresso SDK Builder or does this board's SDK need fixed?

Have a TWR-POS-K81 board. When using (online) MCUXpresso SDK Builder, the only K81 board that appears is the "TWR-K81F150M" and the build is named "SDK_2.4.1_TWR-K81F150M.zip". After downloading the SDK, building and running both demo_apps_led_blinky and driver_examples_gpio_gpio_led, neither one blinks any LEDs.

After examining the board.h and pin_mux.c files and the TWR-POS-K81 User Guide, the following was found:

board.h:

ITEM PORT PIN

Red LED D 11

Green LED D 12

Blue LED D 13

SW3 A 21

SW2 A 4

TWRPOSK81UG.pdf:

ITEM PORT PIN

Red LED C 7

Green LED C 8

Blue LED C 13

Orange LED D 10

Pushbutton A 4

RESULT::

None of the LED port specifications are correct in board.h.

The Orange LED is not even specified in board.h.

There are two switches/buttons listed in board.h but only one in the UG.

When board.h and pin_mux.c files are modified to match the User Guide, the red LED blinks as expected.

Was I given wrong board in MCUXpresso SDK Builder or was this board's SDK based off of another board and not properly changed?

Thanks,

Dan

Hi Dan Davidson,

For K81 materials like the latest SDK the customer must have NDA.
Please contact your local DFAE for assistance on NDA issue.
Please kindly refer to Distributor Network|NXP for more details.

Best Regards,

Robin

Robin,

We have NDA in place (that is how we got the SDK in the first place).

I was trying to determine if it is the correct one or not.

Hi Dan,

Sorry for the inconvenience!
I just got the feedback from related engineer:

There is no SDK support for the TWR-POS-K81.
For this board, the customer should use the TWR-K81F150M.
If there are any differences with I/O - the customer will have to change them manually.

Best Regards,

Robin

Hi Robin,

"If there are any differences with I/O"

Where is the real gpio description ?
