Part Number: 66AK2H14
Hi all,
Software environment: Processor SDK 0.3.01.00.06
On my custom board, I rebuilt the UBOOT and now the UBOOT was up after setting the 66AK2H14 as ARM SPI BOOT MODE.
Then I followed this page 
and tried to boot the Linux from USB mass storage device.
I clearly followed every steps to setup the USB boot environment.
The following instructions seem not complete.
setenv boot usb
setenv args_all 'setenv bootargs console=ttyS0,115200n8 rootwait"
setenv args_usb 'setenv bootargs ${bootargs} rootfstype=ext4 root=/dev/sda2 rw ip=dhcp'
setenv init_usb 'usb start; run set_fs_none args_all args_usb'
setenv get_fdt_usb 'fatload usb 0:1 ${addr_fdt} ${name_fdt}'
setenv get_kern_usb 'fatload usb 0:1 ${addr_kern} ${name_kern}'
setenv get_mon_usb 'fatload usb 0:1 ${addr_mon} ${name_mon}'
saveenv
So I added some other steps as below
setenv boot usb
setenv args_all 'setenv bootargs console=ttyS0,115200n8 rootwait'
setenv args_usb 'setenv bootargs ${bootargs} rootfstype=ext4 root=/dev/sda2 rw ip=dhcp'
setenv init_fw_rd_usb 'setenv rd_spec -'
setenv set_fs_none 'setenv addr_uinitrd -'
setenv init_usb 'usb start; run set_fs_none args_all args_usb'
setenv get_fdt_usb 'fatload usb 0:1 ${addr_fdt} ${name_fdt}'
setenv get_kern_usb 'fatload usb 0:1 ${addr_kern} ${name_kern}'
setenv get_mon_usb 'fatload usb 0:1 ${addr_mon} ${name_mon}'
setenv name_fdt 'uImage-k2hk-evm.dtb'
setenv name_kern 'uImage-keystone-evm.bin'
setenv name_mon 'skern-k2hk-evm.bin'
setenv addr_fdt '0x88000000'
setenv addr_kern '0x82000000'
And the complete UBOOT environment variables were as below
=> print
addr_fdt=0x88000000

Then I typed the BOOT command. The boot message was showed as below

Uncompressing Linux... done, booting the kernel.
You could see that the BOOT sequences was stuck.
From this page
I had set the kernel using 'Kernel low-level debugging functions' and 'early printk'.
But I still had no more things output after 'booting the kernel'.
So how should I do to debug further? How to enable CONFIG_DEBUG_LL? Could anyone help me?

Feng
