How to access GPIOs on FRDM-LS1012A

[hanraaijmakers]

On Arduino connectors of the FRDM-LS1012A there is suppose to be access to the GPIO pins. By default they seem to be mapped to SDHC. How can they be used through the gpio linux driver?

I've managed to get a PBL file with the gpio pins available. The defaults have the SDHC1 enabled, which disables the GPIO pins.

The LS1012A RCW is used for pins assignment.

Look at the QorIQ SDK 2.0 Documentation:

http://www.nxp.com/files/soft_dev_tools/doc/support_info/QORIQ-SDK-2.0-IC-REV0.zip?fasp=1&WT_TYPE=Su...

See the Sections 4.4.4.4 or 4.4.5.5 of this document for RCW changing.

The LS1012A SDK support sysfs for GPIO using.

Have a great day,
