2. Using imx_usb_loader for first install with SPL
--------------------------------------------------
imx_usb_loader is a very nice tool by BoundaryDevice that
allow to install U-Boot without a JTAG debugger, using
the USB boot mode as described in the manual. It is
a replacement for Freescale's MFGTOOLS.
The sources can be found here:
https://github.com/boundarydevices/imx_usb_loader.git
Booting in USB mode, the i.MX6 announces itself to the Linux Host as:
Bus 001 Device 111: ID 15a2:0061 Freescale Semiconductor, Inc.
imx_usb_loader is able to download a single file (u-boot.imx)
to the board. For boards without SPL support, it is enough to
issue the command:
sudo ../imx_usb_loader/imx_usb -v u-boot.imx
Getting U-Boot when SPL support is active, it requires
two downloads. imx_usb_loader downloads the SPL into
OCRAM and starts it. SPL will check for a valid u-boot.img, and
because it is not found, it will wait for it using the y-modem
protocol via the console.
A first install is then possible by combining imx_usb_loader with
another tool such as kermit.
sudo ../imx_usb_loader/imx_usb -v SPL
kermit kermit_uboot
and kermit_uboot contains something like this (set line should be adjusted):
set line /dev/ttyUSB1
set speed 115200
SET CARRIER-WATCH OFF
set flow-control none
set handshake none
set prefixing all
set file type bin
set protocol ymodem
send u-boot.img
c
The last "c" command tells kermit (from ckermit package in most distros)
to switch from command line mode to communication mode, and when the
script is finished, the U-Boot prompt is shown in the same shell.
