Logo IMX6
Change Openembedded Logo Solution
1. Download psplash：git clone git://git.yoctoproject.org/psplash
2. Change Image to .c file and .h file : ./make-image-header.sh xxlogo.h POKY ,then will be create Image file xxlogo.c , xxlogo.h
3. Chage xxlogo.c : #include "psplash-poky-img.h change #include "xxlogo.h"
4. Create autogen.sh shell script, will be create Makefile.
Example
#!/bin/bash
acloal
autoheader
automake
autoconf
7. Run "make" and create the "psplash" "psplash-write".
8. Copy psplash and psplash-write to rootfs in /usr/bin/
9. If you will be remove "progress bar", please remark the code.
Remove psplash_draw_progress function define in psplash.c. In psplash.c.
/* Draw progress bar border */
/*
psplash_fb_draw_image (fb,
(fb->width - BAR_IMG_WIDTH)/2,
SPLIT_LINE_POS(fb),
BAR_IMG_WIDTH,
BAR_IMG_HEIGHT,
BAR_IMG_BYTES_PER_PIXEL,
BAR_IMG_ROWSTRIDE,
BAR_IMG_RLE_PIXEL_DATA);
