imx_loader
i.MX/Vybrid recovery utility
Description
This utility allows to download and execute code on Freescale i.MX5/i.MX6/i.MX7 and Vybrid SoCs through the Serial Download Protocol (SDP). Depending on the board, there is usually some kind of recovery button to bring the SoC into serial download boot mode, check documentation of your hardware.
The utility support USB and UART as serial link.
Installation
Two binaries are available, imx_usb and imx_uart for the two supported connections.
Windows
Two variants have been tested successfully to build imx_usb and imx_uart on Windows:
MinGW
MinGW allows to use the GNU toolchain (including GCC) to compile a native Microsoft Windows application. A MinGW specific make file (Makefile.mingw) is available which allows to build imx_usb/imx_uart with the native make port (mingw32-make.exe). After installing MinGW, make sure you have a compiled copy of libusb available and build imx_loader using:
This dynamically links against libusb, hence make sure to ship the library libusb-1.0.dll along with imx_usb.exe.
Visual Studio
The subdirectory msvc/ contains the project files for Visual Studio 2015. Make sure you have the Visual C++ component installed. There is one solution containing two projects, one for imx_usb and one for imx_uart. The imx_usb project requires libusb to be present at ../../libusb (relative to the msvc) directory. If you use an alternative location or compile libusb from source too, you will have to alter the include/library path in the project settings.
macOS
libusb and pkg-config can be installed via Homebrew.
If imx_usb fails to claim interface, com.apple.driver.usb.IOUSBHostHIDDevice needs to be unloaded so libusb can claim, run:
Usage
Using USB, your device should be detected automatically using the USB VID/PID from imx_usb.conf. Using UART, the user has to specify a configuration file. This file is needed to use the correct protocol variant for the target device (transfer configuration). The configuration file can also contains work item(s).
Work items can also be defined using the command line. By specifying a file in the command line, the utility automatically uses this file as a work item and reads parameter from its header:
However, parameters can also specified manually, e.g.
The UART link uses hardware flow control using RTS/CTS, so make sure those are available. The imx_uart utility will configure the target tty with the right baud rate (115200) and flow control settings:
