Boot

USB SDP

More info at, u-boot/doc/README.sdp

  1. Clone imx_usb_loader
$ git clone git://github.com/boundarydevices/imx_usb_loader.git
$ cd imx_usb_loader
$ make
  1. Build the BSP and copy SPL, u-boot-dtb.img in imx_usb_loader directory
  2. Put the board in “Serial Download Mode”
  3. Plug-in USB-to-Serial and USB OTG cables to Host and Turn-on board
  4. Identify VID/PID using lsusb

Bus 001 Device 010: ID 15a2:0061 Freescale Semiconductor, Inc. i.MX 6Solo/6DualLite SystemOnChip in RecoveryMode

  1. Update the conf files

    imx_usb.conf

    0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf
