Hi all,
I'm trying to display an image inside U-Boot environment using HDMI output (you right, a splash screen!).
I followed the instructions on the "Technical Reference Manual" (section 10.2.5: "Display Controller Programming Guide" (Table 10-60: "DISPC Configuration (GFX pipeline)") and setup GPIO (41 and 60) as Up and Output). Before setting DISPC_CONTROL1.GOTV I copy a bitmap image in memory (base address 0x80500000 (also configured in the relevant registers DISPC_GFX_BA_j)) but all I see is a black screen. But the "Check signal cable" message disappears from the screen when I boot my card (this makes me believe that the monitor receives a signal).
My question is: I am following the right way to configure the DisplaySubSystem? Any suggestions?
