Download the files listed in Section: "Downloadable Files" to the top of the Linux i.MX RT installation.
Install the BSP, as per the respective "Installing and activating cross development environment" document in the "Software" section on the Emcraft site.
From the top of the Linux installation, activate the Linux cross-compile environment by running:
Code Block $ . ./ACTIVATE.sh
Install U-Boot to the target board.
for the IMXRT10XX-EVK boards as per Installing U-Boot to the NXP i.MX RT10XX EVK Board
for the IMXRT1170-EVK boards as per https://emcraft.com/imxrt1170-evk-board/installing-uboot-to-imxrt1170-evk-board
From the top of the BSP installation, go to the Linux kernel tree and install the kernel patch, eg:
Code Block $ cd linux/ $ patch -p1 < ../../linux-flexcan.patch
From the top of the Linux installation, go to the
projects
sub-directory, and patch therootfs
project:Code Block $ cd projects/ $ patch -p1 < ../../projects-flexcan.patch
On the Linux PC intended for execution of the CANsocket test suite, ensure that the following software is installed (Emcraft used Linux PC running the
Fedora 16
(3.1.0-7.fc16.i686.PAE) installation; the other Linux distributives should work too, but may require some additional steps like compilation and installation of the CAN framework kernel modules):Install
can-utils
package on the Linux PC (commands below are for a Fedora host):Code Block $ sudo yum install can-utils ... $
Install and build
can-tests
on the Linux PC:Code Block $ cd ~ $ git clone https://github.com/linux-can/can-tests.git $ cd can-tests $ make $ sudo DESTDIR=/usr PREFIX= make install
Load the CAN kernel modules on the Linux PC:
Code Block $ sudo modprobe can $ sudo modprobe can-raw $ sudo modprobe slcan
Connect the VSCOM USB-CAN adapter to the Linux PC and configure it as follows:
Get the VSCOM USB-CAN serial device name (in the example below it is
ttyUSB0
):Code Block $ dmesg | tail [77641.738206] usbcore: registered new interface driver ftdi_sio [77641.739086] usbserial: USB Serial support registered for FTDI USB Serial Device [77641.747063] ftdi_sio 1-2:1.0: FTDI USB Serial Device converter detected [77641.747348] usb 1-2: Detected FT232R [77641.781982] usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0 [78603.073189] can: controller area network core [78603.073360] NET: Registered PF_CAN protocol family [78618.877319] can: raw protocol [78632.316446] CAN device driver interface [78632.334423] slcan: serial line CAN interface driver
Configure the VSCOM USB-CAN adapter to run with a 1Mbps CAN-bus speed (the
-s8
parameter inslcan_attach
), enable the corresponding network interface:Code Block $ sudo slcan_attach -o -s8 /dev/ttyUSB0 attached tty /dev/ttyUSB0 to netdevice can0 $ sudo slcand -o -s8 -t hw -S 3000000 /dev/ttyUSB0 $ sudo ifconfig can0 up
If you have disconnected the VSCOM USB-CAN adapter from the Linux PC, before reconnecting it back run the following command:
Code Block $ sudo killall slcand
