- Insert the micro SD card in the board, power it up and U-Boot messages should

2. Booting via Serial Download Protocol (SDP)
---------------------------------------------
The mx6ulevk board can boot from USB OTG port using the SDP, target will
enter in SDP mode in case an SD Card is not connect or boot switches are
set as below:
Sw602: 0 1
SW601: x x x x
The following tools can be used to boot via SDP, for both tools you must
connect an USB cable in USB OTG port.
- Method 1: Universal Update Utility (uuu)
The UUU binary can be downloaded in release tab from link below:
https://github.com/NXPmicro/mfgtools
The following script should be created to boot SPL + u-boot-dtb.img binaries:
$ cat uuu_script
uuu_version 1.1.4
SDP: boot -f SPL
SDPU: write -f u-boot-dtb.img -addr 0x877fffc0
SDPU: jump -addr 0x877fffc0
SDPU: done
Please note that the address above is calculated based on SYS_TEXT_BASE address:
0x877fffc0 = 0x87800000 (SYS_TEXT_BASE) - 0x40 (U-Boot proper Header size)
Power on the target and run the following command from U-Boot root directory:
$ sudo ./uuu uuu_script
- Method 2: imx usb loader tool (imx_usb):
The imx_usb_loader tool can be downloaded in link below:
https://github.com/boundarydevices/imx_usb_loader
Build the source code and run the following commands from U-Boot root
directory:
$ sudo ./imx_usb SPL
$ sudo ./imx_usb u-boot-dtb.img
