How to debug second boot loader by calling adi_rom_boot()

I am using the following code segment to call adi_rom_boot() from Linux add-in 1.2 uboot to boot my second boot loader..

It was working initially but all of a sudden it failed to boot.

Is there any way to debug that from adi_rom_boot().

Thanks

A.C.

void *boot_address = (void *)(SPI_BASE + CONFIG_SPI_UBOOT_OFF);

uint32_t boot_flags = 0;

void *hook = (void *)0x00000000;

uint32_t boot_command = 0x00010207; //from spec for SPI boot, auto, SPI2

adi_rom_boot(boot_address, boot_flags, 0, hook, boot_command);
