Hello to everyone.
I’m trying to install UEFI firmware on the KHADAS EDGE-V based on Rockchip RK3399,but it does not work : the HDMI screen connected to the board does not turn on.
What I want to do is to use it for booting FreeBSD 14.x on the KHADAS EDGE-V.
To be able to achieve the goal,I’ve started a thread on the FreeBSD forums,here :
Basically this is what I did.
First of all,I’ve got all the necessary files here :
Then. I created this “script” to use with fdisk /dev/sdi :
label: gpt
label-id: 6265BE94-368D-4AF4-B4B7-A866CF8B2CD9
device: /dev/sdi
unit: sectors
first-lba: 34
last-lba: 249737182
sector-size: 512
/dev/sdi1 : start= 64, size= 8000, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4, uuid=c98ecab1-1b4a-4a5f-90be-47f303afb025, name="loader1"
/dev/sdi2 : start= 8064, size= 128, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4, uuid=c9e72325-f04a-42f2-ba21-765a84c4a97a, name="reserved1"
/dev/sdi3 : start= 8192, size= 8192, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4, uuid=b4a7ee44-049c-4812-b226-77ed60c6b485, name="reserved2"

/dev/sdi5 : start= 24576, size= 8192, type=0FC63DAF-8483-4772-8E79-3D69D8477DE4, uuid=3e9f170a-c378-4c58-a703-2bc18c596f5e, name="atf"
/dev/sdi6 : start= 32768, size= 102400, type=C12A7328-F81F-11D2-BA4B-00A0C93EC93B, uuid=2fb46bfd-b0d7-454a-a156-39f7a7a06ff8, name="efi esp"
and I’ve applied that layout to the disk. And then I did :
dd if=idbloader.img of=/dev/sdi1
dd if=RK3399_SDK_UEFI.img of=/dev/sdi4
dd if=trust.img of=/dev/sdi5
How to “dd” sdi6 ? The file README does not talk about it at all. It does not even specify what’s the content that should be copied inside there. I dd’ed the EFI partition that’s on the sd card sdk,that’s able to boot FreeBSD for sure :
Disk /dev/sdk: 183.35 GiB, 196865949696 bytes, 384503808 sectors
Disk model: MassStorageClass
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 224BEEEC-6B6B-11EF-83C6-002590EC5BF2
Dispositivo Start Fine Settori Size Tipo
/dev/sdk1 32768 135167 102400 50M EFI System
/dev/sdk2 135168 368345087 368209920 175.6G FreeBSD UFS
/dev/sdk3 368345088 384499711 16154624 7.7G FreeBSD swap
doing this :
dd if=/dev/sdk1 of=/dev/sdi6
(first I reduced 112 to 50 mb)…
This is the resulting partitions layout :
It seems it worked,but I used different values than those suggested in the table below :
I can’t use those values,otherwise I get this error :
Fixed by the user @covacat :
Anyway,something is wrong in the procedure,because when I insert the sd card inside the KHADAS-EDGE-V slot,my HDMI screen does not turn on.
Do you know if I should apply a different procedure and tools ? thanks.
