U-Boot Logo Customization
ROM-5721
MIPI-DSI to LVDS (AUO/G070VW01)
- Change the dtb file used from imx8mm-rom5721-a1.dtb to imx8mm-rom5721-a1-dsi2lvds-g070vw01.dtb by modify CONFIG_DEFAULT_DEVICE_TREE in defconfig.
CONFIG_DEFAULT_DEVICE_TREE="imx8mm-rom5721-a1-dsi2lvds-g070vw01"
- Enable some options in defconfig.
CONFIG_DM_PWM=y CONFIG_BACKLIGHT_PWM=y CONFIG_PWM_IMX=y CONFIG_VIDEO_TC358775=y CONFIG_ADVANTECH_LOGO=y
- Put logo bmp file into the directory "tools/logos/".
- Overwrite LOGO_BMP definition at tools/Makefile to specific customer's logo.

Kernel Solution
Modify the drivers/video/logo/logo_linux_clut224.ppm
客製化logo 圖片儲存成png格式
- pngtopnm linuxlogo.png > linuxlogo.pnm // **首次使用者需要apt-get install netpbm**
# pnmquant 224 linuxlogo.pnm > linuxlogo224.pnm // **轉成224色**
# pnmtoplainpnm linuxlogo224.pnm > linuxlogo224.ppm
mv linuxlogo224.ppm logo_linux_clut224.ppm
logo_linux_clut224.ppm替換kernel/drivers/video/logo/logo_linux_clut224.ppm
1、裝載pngtopnm工具。
$ sudo apt-get install netpbm
注:裝載完以后就會有pngtopnm,pnmquant,pnmtoplainpnm三個工具。
2、選取logo的圖片:
首先選取一個自己喜歡的圖片,然后通過GIMP軟體將該圖片儲存為.png格式,
比如儲存為linuxlogo.png.
3、制作.ppm格式的圖片:
$ pngtopnm linuxlogo.png > linuxlogo.pnm
$ pnmquant 224 linuxlogo.pnm > linuxlogo224.pnm
$ pnmtoplainpnm linuxlogo224.pnm > linuxlogo224.ppm
或者
$bmptoppm linuxlogo.bmp > linuxlogo.ppm //生成ppm
$ppmquant 224 linuxlogo.ppm > linuxlogo224.ppm //轉換成224色彩
$pnmnoraw linuxlogo224.ppm > linuxlogo224.ppm //轉換成ascii格式
4、替代原有的圖片。
$ make clean SUB_DIR=./drivers/video/logo/ //來清除logo目錄下的.c和.o檔案
注:apus板子的圖片名叫logo_dec_clut224.ppm,所以只要用第三步生成的圖片替代即可。
Yocto Openembedded Solution
Change Yocto 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);
*/
