On a first look the pinmuxing > looks fishy: 0x0d4 is muxed two times. Hmm, so it is. I'm not really familiar with SDI, I just muxed all the SDI pins, except datapair3. I previously thought that there's only the data and clock pairs for SDI, but the TRM revealed more sdi pins, so I included them. It is well possible that these can be removed: 0x0d0 (PIN_OUTPUT | MUX_MODE1) /* dss_data18.sdi_vsync */ 0x0d2 (PIN_OUTPUT | MUX_MODE1) /* dss_data19.sdi_hsync */ 0x0d4 (PIN_OUTPUT | MUX_MODE1) /* dss_data20.sdi_den */ 0x0d6 (PIN_OUTPUT | MUX_MODE1) /* dss_data21.sdi_stp */ Tomi
