Prepare
For Upgrade firmware, A tool named usb-flash and a new firmware are needed.
New Firmware
Ask PM for help to get the latest firmware like SLCAN-FD0V0102.bin .
Tool
usb-flash is integrated by default in version 20250408 or later.
Check usb-flash :
# usb-flash -v
Advantech HID IAP Console v0.1
For early versions, download the tool from here : usb-flash
And unzip usb-flash to /usr/local/bin/ on DUT.
# tar -zxvf usb-flash.tar.gz -C /usr/local/bin/
# chmod +x /usr/local/bin/usb-flash
Firmware in DUT
Check firmware version in DUT, taking can0 for example:
# /tools/test/adv/can/can_get_firmware_version.sh can0
[ OK ]: can0 Firmware Version : 0102
CAUTION
Firmware upgrades are only supported in V0102 or later versions
Enter Upgrade Mode
Stop slcan driver
# pkill slcanfd
Get Can port
Get can port ttyACMx (x=0、1、2...)
# dmesg | grep slcan
[ 6.880193] can0: slcan on ttyACM0.
[ 6.890344] can1: slcan on ttyACM1.
Swith MCU to IAP mode
# usb-flash -s /dev/ttyACM0
# usb-flash -s /dev/ttyACM1
# usb-flash -s /dev/ttyACM2
... ...
Reboot DUT
Reboot DUT for MCU to enter IAP mode.
# reboot
Upgrade Firmware
Check IAP Mode
Check whether MCU is in IAP mode.If there are nodes hirawx (x=0、1、2...) , MCU is in IAP mode.
# ls /dev/hidraw* -al
crw------- 1 root root 235, 0 Apr 8 05:56 /dev/hidraw0
crw------- 1 root root 235, 1 Apr 8 05:56 /dev/hidraw1
Upgrade Firmware
Taking SLCAN-FD0V0102.bin as an example of the file name of the latest firmware.
Suppose SLCAN-FD0V0102.bin is located in the root folder of the USB flash disk.
Adjust SLCAN-FD0V0102.bin and /run/media/sda1/SLCAN-FD0V0102.bin according to your actual situation.
# cp /run/media/sda1/SLCAN-FD0V0102.bin ./
# usb-flash -f SLCAN-FD0V0102.bin
Enter Y for each can to start upgrade process.
