Hello all, I'm having problems with a framebuffer on /dev/fb0 using the DENX 2.4.24 kernel
I have added the Linux Console Driver for the Epson S1D13806 http://www.erd.epson.com/vdc/RelSoft/generic/s1d13xxx_linux.zip which prints the following to the console as it is initialized Console: switching to frame buffer device S1D13xxx: fb0: s1d13xxx frame buffer device S1D13xxx: Display 240 x 320 8Bpp Whenever the framebuffer is accessed a call is made to the function PROC_CONSOLE in fbcon.c which always returns -1 because the info->display_fg pointer is NULL None of the functions that call PROC_CONSOLE test for this error value. Some commands seem to work because later functions test for con == -1. (FBIOGET_FSCREENINFO works because fbgen_get_fix tests for it) Ofher commands fail because later functions assume the con passed is correct and use it as an index into the fb_display array. (FBIOGETCMAP fails because fbgen_get_cmap doesn't test for it) I guess I'm lucky the whole O/S is not crashing. Is there a way to have PROC_CONSOLE always return a valid value? Or should all the functions in fbgen.c be fixed to handle con == -1? I would like to leave the serial port (/dev/ttyS0) as the console and I don't actually want the framebuffer as the console. I would prefer that only Konqueror/Embedded with Qt/Embedded use the framebuffer. Any assistance would be greatly appreciated. Chris ** Sent via the linuxppc-embedded mail list.
