Espressobin anyone ?

Sun Jun 2 16:40:54 UTC 2019

Hi

I managed to get it to boot with the following:

setenv fdt_name 'efi/boot/armada-3720-espressobin.dtb'
setenv image_name 'efi/boot/bootaa64.efi'
setenv bootmmc 'mmc dev 0; fatload mmc 0:1 $kernel_addr $image_name;fatload mmc 0:1 $fdt_addr $fdt_name; bootefi $kernel_addr $fdt_addr'
run bootmmc

Then when the FreeBSD loader fails to load the kernel enter:

set currdev=disk0p2
Boot

That will boot the kernel:

/boot/kernel/kernel text=0x92aab0 data=0x190f48+0x84ab1c syms=[0x8+0x137580+0x8+0x12372b]
Using DTB provided by EFI at 0x8000000.

However, the MMC/SDcard fails to be found so it will stop at mounting root.

Having a disk on the SATA port can make it work from there though.

The etherswitch is not found, but the single “nata” port does show up..

All in all the support is barely enough to boot a kernel, but a long way from being useful.

You can use 12-stable as well, the same support seems to be present there, and its much more stable, -current as is today panics…

Oh, and you need to get the “right” .dtb file, otherwise you get panic’s etc.

YMMV…
