Hi Alice, many thanks for your link (I don't know why it not appear for me,... it was searched but,...),
About your answer,... apparently debug sessions works well,... it was tested in LPC845max board:
I loaded two full SDK' examples (SDK has been fully update), in both cases the error or warning appear when debug session is started.
1st Example. Demo "led_blinky". It seem work with the warning in the debug console. The debug session start (it activate the error in red text) but tha app run and red led blinks as expected.
2nd Example. Driver "gpio_led_output". It seem works, also, whith the warning in the debug console. As previous the error message is activate when debug start. Green led blinks when SW2 switch is pressed (uart data not tested,...)
Without more information I will closed this issue, if it appear some more data I will inform you.
Thanks.
