We have a board that we developed a little while ago and succesfully ported uClinux 2008R1-RC8 to. The board was based on the BF537-stamp board. We have a new requirement that we need to add some GPIO to it - however when trying to add GPIO support as shown at:
Device Drivers ---> [*] GPIO Support ---> [*] /sys/class/gpio/... (sysfs interface)
When I goto my kernel settings I do not have "GPIO Support" as an option under device drivers. Either this means I do not have some pre-required item selected or I cannot enable gpio-sysfs support. Is there any way I can get userspace GPIO support under uClinux 2008R1-RC8?
Thanks in advance
