Hello,
Thanks for your attention.
I gotta know the purpose of function omap_get_config. I added an
item related to OMAP_TAG_LCD to my board file, so it can register the
fb device successfully.
But I have another question. When I compile the frame buffer into
kernel, there is not any output information in my serial terminal
since
Uncompressing
Linux............................................................................................
done, booting the kernel. If I compile it as module, it is fine.
However, debugging the module is not convenient on my board. I need to
add it to root filesystem and burn it to the flash.
I used u-boot as my bootloader. The bootargs is set to be
" noinitrd console=ttyS0,115200n8 root=/dev/mtdblock4 rootfstype=jffs2
init=/linuxrc mem=64M ".
How can I solve this problem? Thanks very much !
