incorrect pin direction using NXPXSPRESSO

Hi,

We work on MIMXRT1051CVL5B using NXPXSPRESSO, and we have issue with some pin directions:

1. PMIC_ON_REQ should be an output pin that enables the main board power once the SNVS voltage is up. The SW seems to consider it as an input signal, and it can't be changed.

2. pin G13 JTAG_TDO should be defined as output, but the SW seems to consider it as an input signal, and it can't be changed.

Can you please help define the correct direction for the pins?

Hello
Hope you are well.

1. PMIC_ON_REQ is output and the direction cannot be changed by software:

2. The default from the datasheet is an input however as JTAG is the default functionality we can say that it is:

Best regards,
Omar

Hi,

We know the direction of those pins, but our problem is that they are defined incorrectly in the SW NXPXSPRESSO.

We don't know how to change the incorrect pin's direction in the SW

This is more a typo of the tool however the direction of those pins is not affected by this. In the case of G13, the direction is given by functionality. Depending on the functionality, the tool can change direction. On the PMIC_ON_REQ pin, the direction cannot be changed.
It will be helpful to report this typo to avoid further confusion on the direction of the pins.
