[U-Boot] [U-boot] not support parsing Android's boot.img format ?
Hi, experts:
It seems current uboot does not support parse boot.img which saved in NAND chip.
Boot.img contains : kernel.img and ramdisk.img
It contains a header struct:
struct boot_img_hdr
{
unsigned char magic[BOOT_MAGIC_SIZE];
unsigned kernel_size; /* size in bytes */
unsigned kernel_addr; /* physical load addr */
unsigned ramdisk_size; /* size in bytes */
unsigned ramdisk_addr; /* physical load addr */
unsigned second_size; /* size in bytes */
unsigned second_addr; /* physical load addr */
unsigned tags_addr; /* physical addr for kernel tags */
unsigned page_size; /* flash page size we assume */
unsigned unused[2]; /* future expansion: should be 0 */
unsigned char name[BOOT_NAME_SIZE]; /* asciiz product name */
unsigned char cmdline[BOOT_ARGS_SIZE];
unsigned id[8]; /* timestamp / checksum / sha1 / etc */
};
Nand boot cmd usually should retrieve kernel.img from boot.img.
Best wishes,

Not sure what the purpose of your message is.
Are you asking if U-Boot is able to parse android's img forat, as your message's subject implies? But in the body you seem to know it does not.
Are you asking for someone to provide a patch? There is no indication of such a request in your message, and besides, I don't think this U-Boot tehcnical list would be the place to make such requests for volunteer work.
Are you considering whether this change is valuable or not, in order to determine if you should submit a patch? If so, the I suggest that you don't ask questions first, since anyway you'll have to post the patch eventually, so just post it directly, and list any explanations, questions, etc below the '---' line.
Best wishes,
Amicalement,
Hi, Albert: Sorry for making trouble for you! I just wants to make sure uboot not support this feature now.
Maybe i will submit a patch in the future.
