Hi there,
I am getting error don't know the reason,
It's showing : start4x.elf: is not compatible, this board requires newer software
I've checked firmware version it's up to date. 11th jan 2023 release, Raspberry pi 4 version is Rev1.5 8GB RAM.
Ubuntu 20.4 is required as it supports ROS noetic and later version of ubuntu don't support ROS1.
Also I've tried booting on Pi 3B+ it boots without any error.
please help me out of this.

Hello I found a similar issue, boot would not start and complained that start_x.elf was not compatible and needed newer software.
Turns out apparently my RPi 4 required a firmware update (odd because the RPi says it is from 2018).
I found the fix in this forum: https://forums.raspberrypi.com/viewtopic.php?t=346302
I copied manually all files start*.elf and fixup*.dat from this repo https://github.com/raspberrypi/firmware/tree/master/boot to the boot partition in the SD system-boot partition to update the firmware
After that it booted and started the set up process.
Unfortunately I am stuck again because the setup crashed during keyboard configuration...
Hope it helps you
The forum links to this PDF guide describing the firmware update process: https://pip.raspberrypi.com/categories/685/documents/RP-003476-WP/RP-003476-WP-1.pdf
Also the new issue with Ubuntu MATE setup process crashing during keyboard configuration is very similar to the one described here: Installing Ubuntu mate - #9 by Zero Any ideas are welcome
