How to boot FreeBSD installed on the sd card on the Khadas Edge-V instead of Android

Probably my adapter does not work because the pin at 3.3V should be closed with a jumper.

I'm not sure anyway. I see that it is not short and it does not make a lot of sense to e to put a jumper there...

On the tutorial,dude did it using your adapter,which sounds have a better look and it seems better engineered :

That's probably the reason why my adapter doesn't work....

in order to maximize your chances try out these things:
1. check the logic hi voltage level on the adapter and the minicomputer. they must match.

completely disconnect the adapter from minicomputer, but keep both powered up. with a multimeter that reads DC volts check out the voltage between ground and RX, then TX on both devices. common UART voltages can be 1.8V, 3.3V or 5V. if your board is 3.3v your adapter must also be prepared for that level. some adapters indeed have a jumper that select the logic hi voltage. if you have a matching combination then you don't need to worry about any missing jumper.

2. in minicom try different combinations of flow control and reboot the board each time to generate input data
CTRL+ALT+Z O (configuration) -> serial port setup -> F,G. most common is hardware flow control off, software flow control off.
also make sure you have sane stop bits configured. 8N1 is most common. goes without saying that you also need to have the proper speed configured, otherwise you get trash on your terminal. try to flip RX/TX in case you got them wrong.

3. use a laptop that is battery powered to connect to that adapter via USB. sometimes when devices are plugged in and have long ground (Protected Earth) loops small voltage differences in that common ground can cause havoc on small signals like that UART. if you don't have a laptop with minicom at least make sure both the PC and the minicomputer are plugged in the same wall power socket.
 
Thanks for your help.

This time I used this adapter :

https://www.amazon.it/dp/B08T24NML9

It looks like the original pine one,but I am still not able to display the messages on the screen as soon as I turn on the RockPro64 board.


1) The yellow jumper on the serial console is set to 3V3 (I didn't touch the yellow jumper as it have been placed by default

2) I've connected a wire to the ground (GND) on the adapter and the other end to pin#6 of the board (red cable)

3) I've connected a wire to RTX on the adapter and the other end to pin#8 of the board (orange cable)

4) I've connected anoter (red) wire to TXD to the adapter and the other end to pin#10 of the ROCKPro64,but I have also tried without

Please give a look at this picture :

Then,on Linux I put hardware and software flow control = yes and :

On Terminal 1 :

Code: 
# screen /dev/ttyUSB0 1500000


On Terminal 2 :

Code: 
# minicom -D /dev/ttyUSB0 -b 1500000

And then I attached an HDMI cable to my monitor,to see if it was able to boot and I powered on the board. Well,it booted regularly,but on the Minicom console I didn't see any message :

https://ibb.co/7NzmpgFK
https://ibb.co/s96D21pN
 
As u can see,black = GND = pin 6 ; brown = RTX = pin 8. The author says that the white wire is not necessary to display the messages.

yes in your red/orange pic gnd goes to 8

Now it's working. I can't believe that after "1000" tries,I have placed the wires to the wrong pins all the time.

Now that's working on the RockPro,I will try with the KHADAS EDGE-V board. My real target.
 
Anyway I suspect that, generally speaking, the problem was to run "screen /dev/ttyUSB0 1500000". I didn't run it before minicom and it worked...
 
Et voila'. Below there is / are the reason(s) why the KHADAS-Edge V does not boot if on the sd card is installed UEFI instead of u-boot :

This is why :

Nor should the material about building RK3399_SDK_UEFI.img also talk about the "efi esp" content, which is a separate thing.

In :

Number Start (sector) End (sector) Size Code Name

6 32768 262143 112.0 MiB EF00 efi esp

"efi esp" is a particular type of msdosfs file system that is to contain FreeBSD's EFI Boot Loader (FreeBSD aarch64 context used below, not what you were using):

EFI/BOOT/bootaa64.efi

That file is a copy of FreeBSD's aarch64 /boot/loader.efi :

# diff /boot/loader.efi /boot/efi/EFI/BOOT/bootaa64.efi

So: no differences. In the context for the above,/boot/efi is the mount point where the file system in the "efi esp" was mounted to be visible in the FreeBSD file system.

Note: the EFI/BOOT/ capitalization convention is my personal one, not necessarily what FreeBSD normally uses.

RK3399_SDK_UEFI looks for and finds that EFI/BOOT/bootaa64.efi and then loads and uses it.

still it should present the edk2 interface / setup or maybe say something about files missing on the esp.
im sure the rk356x one 'worked' without one
 
Remembering that this is the disk structure that I've got after having installed UEFI on the KHADAS Edge-V (that has a RockChip RK3399) :

Code: 
Disk /dev/sdi: 119.08 GiB, 127865454592 bytes, 249737216 sectors
Disk model: STORAGE DEVICE
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

/dev/sdi6   32768 262143  229376  112M EFI System

I want also remember how I have obtained the partitions from sdi1 to sdi6 :

Code: 
dd if=idbloader.img of=/dev/sdi1
dd if=RK3399_SDK_UEFI.img of=/dev/sdi4
dd if=trust.img of=/dev/sdi5
dd if=/dev/sdk1 of=/dev/sdi6

Regarding "sdi6",assuming that I should not do :

Code: 
dd if=/dev/sdk1 of=/dev/sdi6

because sdk1 contained the u-boot that has been installed when I have installed FreeBSD on the RockPro64 board,I have removed it and I've created a new partition,of the same size and type and label (efi esp / fat16) copying the files that are stored on the same kind of partition but on the sd card where I have installed FreeBSD for the RockPro64. I repeat,without using dd,but only cp -r *.

I have started the serial connection and these are the log messages that I've got :

��������� : STUCK here.
 
It seems to me that the efi partition should be empty.

covacat : do you think that the error "GPT 0x3190d20 signature is wrong" could be relevant ?

it's not. if you google search for it you will find successful boot logs with that message

that stops suddenly remembers to me the error that you have talked about some days ago,related to the bug of the frequency,but is was on the Radxa board,not on the Khadas / RK3399...related the missing of the iommu...
 
well that pll bug should only matter on smalish "non standard" hdmi resolutions and you should probably get a fuxed up display not a total hang
 
What about these interesting lines ?

Code: 
No find bl30.bin
No find bl32.bin

And in your opinion,it makes sense to load uboot when I've installed UEFI ?

Code: 
Load uboot, ReadLba = 2000

It seems that UEFI fails because it does not find bl30.bin / bl32.bin and then u-boot is called ? But where is stored u-boot ?
 
bl3x bin is arm trusted firmware. bl31 is usually ok, boards work without bl32 (optee)
ATF exports various apis that kernel can use
the starting u-boot string may be hardwired in idbloader.bin (which probably has the same origin with u-boot)
anyway ATF seems to run ok and then spl/tpl does not seem work
spl/tpl (second/third program loader)
 
From the ML :

Per the above, your GPT is still messed up.

> LoadTrust Addr:0x4000
> No find bl30.bin
> No find bl32.bin
> Load uboot, ReadLba = 2000
> Load OK, addr=0x200000, size=0xf0000

Per the above 2 lines, you still have U-Boot
in place and it is found, loaded, and used.
