Enable SDP protocol support in SPL for DH i.MX6 DHSOM, now that those
components fit into the SPL due to LTO.
To start U-Boot via SDP upload on i.MX6 DHSOM based board, proceed as follows:
- Compile imx_usb [1] .
- Power off the i.MX6 DHSOM based board.
- Connect both USB-serial console and USB-OTG miniB ports to host PC.
- Switch board to USB boot mode.
- Power on the board.
- Verify using '$ dmesg' that a new device has been detected as follows:
New USB device found, idVendor=15a2, idProduct=0054, bcdDevice= 0.01
New USB device strings: Mfr=1, Product=2, SerialNumber=0
Product: SE Blank ARIK
Manufacturer: Freescale SemiConductor Inc
- Upload U-Boot SPL:
$ imx_usb u-boot-with-spl.imx
- Wait for SPL to come up, the following print ought to be the last on
UART console:
SDP: handle requests...
- Upload U-Boot proper:
$ imx_usb u-boot.img
