i have a i.MX53 QSB and i want to use the CSPI on the expanstion-port. Therefore i muxed the DISP0_DAT0 Pin to CSPI-SCLK, but there is already a signal on it. Even if i muxed it to gpio and set the value, this signal is still present. I controlled the mux with the mxc_iomux_v3_get_pad function from iomux-v3.c and everything seems right.

Is there anything that also uses the DISP0_DAT0 pin i don´t know or i miss?


best regards,
