About

These are my notes about the Seeed Studio Odyssey X86J4105 board.

Firmware/BIOS/UEFI

See firmware.

USB keyboards

Be aware that (non)-composite USB keyboards can only be used to enter the BIOS (by pressing the DELETE key) when Fast Boot is disabled (which is the default after a BIOS Restore Defaults).

Poweroff

See https://forum.seeedstudio.com/t/how-to-completely-turn-off-the-network-interfaces-while-odyssey-x86j4105-is-turned-off/255557

Poweron (using Wake-On-LAN)

Make sure you enable the Wake-On-LAN feature in the Chipset page of the firmware:

Then you can send a Wake-On-LAN "Magic Packet" from a local network interface to one of the odyssey network interfaces mac addresses, e.g.:

sudo etherwake -i enp3s0 00:e0:4c:01:93:a8

UEFI Boot Loader

Since the board ships with Windows 10 pre-installed, the UEFI bootloader retains the Windows Boot Manager entry as seen by:

efibootmgr --verbose

The command should return the current boot settings, something alike:

BootCurrent: 0001
Timeout: 5 seconds
BootOrder: 0001,0002,0000,0005
Boot0000* Windows Boot Manager	HD(1,GPT,93faa71b-80e1-42f4-a7dd-0fb3a1c1a75e,0x800,0x32000)/File(\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI)WINDOWS.........x...B.C.D.O.B.J.E.C.T.=.{.9.d.e.a.8.6.2.c.-.5.c.d.d.-.4.e.7.0.-.a.c.c.1.-.f.3.2.b.3.4.4.d.4.7.9.5.}....................
Boot0001* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\SHIMX64.EFI)
Boot0002* UEFI: Built-in EFI Shell	VenMedia(5023b95c-db26-429b-a648-bd47664c8012)..BO
Boot0005* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\GRUBX64.EFI)..BO

Manually remove the Boot0000 entry with:

efibootmgr --verbose --bootnum 0000 --delete-bootnum

The command should return the current boot settings, something alike:

BootCurrent: 0001
Timeout: 5 seconds
BootOrder: 0001,0002,0005
Boot0001* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\SHIMX64.EFI)
Boot0002* UEFI: Built-in EFI Shell	VenMedia(5023b95c-db26-429b-a648-bd47664c8012)..BO
Boot0005* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\GRUBX64.EFI)..BO

Or better yet, remove all entries, as in my case:

efibootmgr --verbose --bootnum 0001 --delete-bootnum
efibootmgr --verbose --bootnum 0002 --delete-bootnum
efibootmgr --verbose --bootnum 0005 --delete-bootnum

Delete the boot order (grub-install will re-create it):

efibootmgr --verbose --delete-bootorder

Then reinstall the ubuntu boot entry with:

grub-install

The end result should be:

BootCurrent: 0001
Timeout: 5 seconds
BootOrder: 0000
Boot0000* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\ubuntu\shimx64.efi)

Then reboot the machine:

reboot

After reboot, the boot settings should be something alike:

BootCurrent: 0000
Timeout: 5 seconds
BootOrder: 0000,0001,0002
Boot0000* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\SHIMX64.EFI)
Boot0001* ubuntu	HD(1,GPT,e2daca90-f32f-4d3e-b696-0244329c6551,0x800,0x100000)/File(\EFI\UBUNTU\GRUBX64.EFI)..BO
Boot0002* UEFI: Built-in EFI Shell	VenMedia(5023b95c-db26-429b-a648-bd47664c8012)..BO

NB The entries after Boot0000 are automatically populated by the UEFI.

UEFI Reboot To Firmware

The system can reboot to the firmware using:

systemctl reboot --firmware-setup

For more details see:

SystemD will manipulate these UEFI variables:

efivar --name 8be4df61-93ca-11d2-aa0d-00e098032b8c-OsIndicationsSupported --print
efivar --name 8be4df61-93ca-11d2-aa0d-00e098032b8c-OsIndications --print
GUID: 8be4df61-93ca-11d2-aa0d-00e098032b8c

Network Boot

See Network Boot.

Ubuntu

Ubuntu 20.10 works out of the box.

WiFi

The Wifi/Bluetooth module has two IPEX MHF4 RF antenna connectors.
