Modifications are certainly a must: e.g. 2.4.20 in drivers/video/tx3912fb.h thereis _only_ framebuffer definitions for the nino: <pre> #if defined(CONFIG_NINO_4MB) || defined(CONFIG_NINO_8MB) #define FB_X_RES 240 #define FB_Y_RES 320 #if defined(CONFIG_FBCON_CFB4) #define FB_BPP 4 </pre> while 2.4.0-test9 carries the _good_ information for the velo 1, velo 500 and for the helio ( the code for the nino is missing here). In drivers/video/r3912fb.h ( which seems to be the historic version of tx3912fb.h, ouch what a chaos :-( <pre> #ifdef CONFIG_PHILIPS_VELO # ifdef CONFIG_PHILIPS_VELO1 # define FB_X_RES 480 # elif defined(CONFIG_PHILIPS_VELO500) # define FB_X_RES 640 # endif # define FB_Y_RES 240 # ifdef CONFIG_PHILIPS_VELO_4GRAY # define FB_BPP 2 # else /* CONFIG_PHILIPS_VELO_16GRAY */ # define FB_BPP 4 # endif # define FB_IS_GREY 1 # define FB_IS_INVERSE 0 # define VIDEORAM_SIZE (FB_X_RES * FB_Y_RES * FB_BPP / 8) </pre> On the other hand the mobilon needs <pre> # define FB_X_RES 640 # define FB_X_RES 240 # define FB_BPP 4 </pre> This information ( and what else which might be of interest to make the LCD working on this thing) must have get lost on the kernel's way. I really wonder where to find a more or less functional version of the kernel code to start with. -- Volker Jahns, Volker.Jahns@xxxxxxxxxxx, http://thalreit.de, DG7PM
