Software

The ICnova A20 SODIMM is supported by the official Buildroot, Kernel and U-Boot, support has been added with the corresponding releases listed in the table below:

Buildroot 2023.11 https://buildroot.org/
Kernel 6.5 https://kernel.org/
U-Boot v2024.01 https://u-boot.org/

The ICnova A20 SODIMM features an on-board hardware-bootloader which can boot the module from SD-Card.


To build new software for the ICnova A20 SODIMM on an ICnova_ADB4006 a buildroot environment must be prepared following the official documentation on https://buildroot.org/docs.html.

Then proceed to build the software by following the steps listed below:

buildroot$ make clean
buildroot$ make icnova-a20-adb4006_defconfig
buildroot$ make

The generated software image can then be flashed onto a SD-Card (e.g. located at /dev/sdc):

buildroot$ sudo dd if=output/images/sdcard.img of=/dev/sdc bs=4096

Then insert the SD-Card into the ICnova_ADB4006.


The ICnova A20 SODIMM on an ICnova_ADB4006 will then boot from the SD-Card and provide a linux console on the serial interface. Login as "root" for which no password is set.
