[U-Boot] imx6: USB SDP failed for u-boot-dtb.img

[Jagan Teki]

Hi,

U-Boot SPL 2018.03-rc3-00111-g0cb2734156-dirty (Mar 06 2018 - 17:19:36 +0530)
Trying to boot from USB SDP
SDP: initialize...
SDP: handle requests...

and SPL reenumerated USB VID/PID as
[24774.255201] usb 1-2: new high-speed USB device number 101 using xhci_hcd
[24774.425174] usb 1-2: New USB device found, idVendor=0525, idProduct=b4a4
[24774.425181] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[24774.425185] usb 1-2: Product: USB download gadget
[24774.425189] usb 1-2: Manufacturer: FSL

HID v1.10 Device [FSL USB download gadget]

Now I've launched u-boot-dtb.img

$ imx_usb u-boot-dtb.img
...
vid=0x0525 pid=0xb4a4 file_name=mx6_usb_sdp_spl.conf
config file <.//mx6_usb_sdp_spl.conf>
parse .//mx6_usb_sdp_spl.conf
Trying to open device vid=0x0525 pid=0xb4a4

Here is mx6_usb_sdp_spl.conf file
   mx6_spl_sdp
   hid,uboot_header,1024,0x910000,0x10000000,512M,0x00900000,0x40000

Look like the u-boot-dtb.img has FIT header and imx_usb can't process
the same, any help?
