如何确认nand.img分区里是否有splash.bmp ?挂载后啥也看不到,不像SD卡镜像都能查看各个分区内容
genimage-nand.cfg文件:
flash nand-128M {
pebsize = 128K
numpebs = 1024
minimum-io-unit-size = 2048
}
image sysimage-nand.img {
flash {}
flashtype = "nand-128M"
partition u-boot {
image = "u-boot-sunxi-with-nand-spl.bin"
size = 512K
}
partition splash {
offset = 0x80000
image = "splash.bmp"
size = 512K
}
partition kernel {
offset = 0x100000
image = "kernel.itb"
size = 5M
}
partition rom {
offset = 0x600000
image = "rootfs.squashfs"
}
}

这个问题是图片格式问题，修改为RGB888就行了，原来的是ARGB888，RGB565格式也会提示Error: compression type 3 not supported
