Hello Port ARM!

I have a MNT Reform2 modular laptop with the Freescale LS1028A CPUmodule, but only a very vague understanding of how booting arm really works.

I know that a specific u-boot will be required, some dtb(?) and thatu-boot has very poor support for this particular processor in that itdoes not support the onboard MMC nor is able to provide graphics outputon the built-in screen (I work around this by using the system's onboardttl serial port)

My ambition is to run NetBSD on this system, and I've gotten a kernel toboot with this CPU module by first loading u-boot from themanufacturer's SD card, stopping the boot process and swapping the SDcard for the netbsd aarch64 generic install image.

This seems to have used the UEFI boot method. It won't automaticallyboot the kernel though, as the root partition seems to be on "hd0b".

Once the kernel is loaded it can't enable the second core and doesn'tfind any disks. The CPU is seen as "unresponsive", none of the MMCdevices are found nor the SSD, and lots of other devices are "notconfigured".

I think the manufacturer-provided (for linux) dtb is loaded, I eventried using the "dtb" command in the netbsd bootloader but the dmesgresults is the same.


What would be the way forward from here?

I also have the older i.mx8mq CPU module at hand and will try that onetoo once I get a thermal conductive pad so I can heasink it. Thereexists a netbsd-bundled dtb for this chip and u-boot can output to thegraphics console so if I can't get the faster module working, the slowerone should have a better chance of success.
