Subject: [U-Boot] Boot Linux kernel with initramfs fails

Hi everyone,

We made a custom board based on imx6solo.
I have the same problem !

I am using Mfgtools in order to flash the eMMC. In this regard, I made 
my own manufacturing u-boot, and linux kernel too.

I have some trouble booting linux kernel with initramfs. I built linux 
kernel with CONFIG_BLK_DEV_INITRD, so Kbuild generates 
usr/initramfs_data.cpio which is integrated into the kernel.

We have an MX6Q Sabre SD eval board so I could compare differences 
between each log kernel boot. Using Mfgtools with manufacturing firmware 
provided by freescale on my MX6Q SabreSD, in the log, there is the line 
"Unpacking initramfs...".

I notice that on my custom board, this line is not present, so there is 
a problem with this. In order to debug, I print in populate_rootfs 
(init/initramfs.c file) the value of "initrd_start" variable. I notice 
that initrd_start is 0, so the code below inside the "if" is not executed :

    if (initrd_start) {

    #ifdef CONFIG_BLK_DEV_RAM

          int fd;

          printk(KERN_INFO "Trying to unpack rootfs image as
    initramfs...\n");

          err = unpack_to_rootfs((char *)initrd_start,

                    initrd_end - initrd_start);

          if (!err){

               free_initrd();

               return 0;

          } else {

               clean_rootfs();

    unpack_to_rootfs(__initramfs_start, __initramfs_size);

          }

          printk(KERN_INFO "rootfs image is not initramfs (%s)"

    "; looks like an initrd\n", err);

          fd = sys_open((const char __user __force *) "/initrd.image",

    O_WRONLY|O_CREAT, 0700);

          if (fd >= 0) {

               sys_write(fd, (char *)initrd_start,

    initrd_end - initrd_start);

               sys_close(fd);

               free_initrd();

          }

    #else

          printk(KERN_INFO "Unpacking initramfs...\n");

          err = unpack_to_rootfs((char *)initrd_start,

                    initrd_end - initrd_start);

          if (err)

               printk(KERN_EMERG "Initramfs unpacking failed: %s\n", err);

          free_initrd();

    #endif

          return 0;

    }

In order to know whereinitrd_startis initialized, I looked into the 
other sources and I notice it is initialized in arch/arm/mm.init.c, 
function arm_memblock_init, with the variable phys_initrd_start :

/* Now convert initrd to virtual addresses */

   initrd_start = __phys_to_virt(phys_initrd_start);

   initrd_end = initrd_start + phys_initrd_size;

phys_initrd_start is initialized in the same file arch/arm/mm.init.c, in 
functions early_initrd, parse_tag_initrd, parse_tag_initrd2 and 
early_init_dt_setup_initrd_arch

I used printk in these functions, but it appears that none of them are 
executed, so phys_initrd_start is not initialized, and obviously 
initrd_start not too.

So, do I have to call early_initrd by myself in my board setup code, or 
do I miss some configuration in my kernel ?

My kernel hangs after the last line, instead of doing "Freeing init 
memory: ..." but I don't know if it comes from the same problem or not...

Anyway, can you tell me if my initramfs problem comes from 
missconfiguration ?

Do you have any idea where my mistakes are ?

I searched in linux code, on Internet, but I don't see any solution...

Thanks a lot !

Regards,
