usb reset:

Marvell>> usb reet
USB is stopped. Please issue 'usb start' first.

So usb start:

Marvell>> usb start
(Re)start USB...

Nice!

Then ext2ls:

Great!

No I have to check how to boot from here.

Actually, only one of the two USB ports works in uboot.
The USB stick is only detected on the port the closer to the Ethernet socket.

By slightly modifying the tftp boot variables, I have managed to boot from the USB drive.

setenv ipaddr 192.168.1.19
setenv serverip 192.168.1.42
setenv load_initrd_addr 0x3000000
setenv load_image_addr 0x02000000
setenv usb_setup 'usb start'
setenv load_image 'echo loading uImage from usb ...; ext2load usb 0:1 $load_image_addr boot/uImage'
setenv load_initrd 'echo loading uInitrd from usb ...; ext2load usb 0:1 $load_initrd_addr boot/uInitrd'
setenv set_bootargs 'setenv bootargs "console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts earlyprintk=serial"'
setenv bootcmd_exec 'echo Booting Debian . . .; run usb_setup;  run set_bootargs; setenv fdt_skip_update yes; setenv initrd_high 0xffffffff; run load_image; run load_initrd; bootm $load_image_addr $load_initrd_addr'
setenv bootcmd 'run bootcmd_exec; run bootspi'
boot

Note that the bootspi is not working because not present in this version of uboot.

Is it safe to just do a saveenv now or do I have to make some changes before?

After some time, I have the following kernel error in the console:

Do you know if this is an issue?

That's very good to know and noted loudly in the installation instruction!

I think it best that you go through the Steps in the USB installation instruction:

https://forum.doozan.com/read.php?2,76314,91094#msg-91094

You might find something we did not before. And we can improve the instruction.

The IRQ problem above seems to be specific to the fan alarm so it does not hurt anything. However, I think I should look at the DTS again to see if we need to add or remove something.

Theses instructions only use USB for rootfs and flash kernel to flash, isn't it?

Now that I can boot directly from USB, even the kernel, I think I only have to change the uboot env, right?

Yes. If you can go through similar steps. Then we have a new instruction to boot directly from USB :)

So could you copy the Steps and revise them with what you just did (in a new post here in this thread)? Of course, it's your instruction so please write your own explanation if you'd like in each step. It's basically the outline that should be similar.

Ok, I see.

I have installed openmediavault on the NAS and let it run for almost two days, no issue detected, Ethernet and the two sata ports are working.

Only the two disk leds are declared in the DTS so the STATUS, LAN and POWER leds are missing but they may be accessible from the external microcontroller and trigger by the serial port. I did not try yet and did not tried other GPIO.

But I have noticed that if I reboot the system, interrupt u-boot and paste the "setenv" commands, it does not work, I have:

Marvell>> setenv serverip 192.168.1.42
Unknown command 'setenv' - try 'help'

If I enter the commands manually, it seems to work but I cannot find them all with "printenv".

Have you already this strange behavior on reboot? Maybe once I will save the env, the issue won't be there anymore.

For now, I have to pull the power cord to reboot the box.

rreignier,

I don't have this box. So all tests were done by users on this thread.

Yes. Once you save envs then you will know that the box can boot automatically without manual interruption. But please do read again the Installation Instruction steps to see if the issue you are seeing was discussed.

Hi,

I was able to activate both sata in u-boot fo Synology DS218j using

mw.l f1018100 000ff000;

scsi init -- found both HDDs.

But after booting in Linux I could not find sdb.

I'm revisiting this topic and don't recall we have the serial pinouts post for RS816, DS116, or DS118. If you own one of these boxes, please post the serial pinouts.

Thanks!

Thanks, I found that too. But that was DS212+, i.e. not one of these 3 boxes. So the questions to users in this thread is "do they all have same pinouts like below?"

1 3.3V
2 GND
4 TX
6 RX

I used this pinout successfully with these boxes in the past: DS214 (trying to unbrick now), DS413J, DS413 and DS118. I would bet that if you see a connector with 6 pins that it will be the serial port and that is uses this layout.

I do use only 2, 4 and 6. A common plug that is used for connecting servos in RC model flight fits perfectly.

Thanks Jan! that's answered my question.

On your boxes, is this orientation of the pins correct? pin 1 is marked with a triangle

So I've confirmed the pins layout.

2 4 6
1 3 5

Does not matter which orientation, Pin 1 is identified by a marking (either white mark or arrow). From there, the pins layout above is correct.

What Jan said above is good info:

In addition to that, a CD-ROM-SounDBlaster-Audio-Cable with the small white header also fits perfectly to pins 2 4 6. This might be the best, because the cable is shielded.

Does anybody know how to request for GPL source (u-boot) from Synology? what email address I can send the request to (without having to create an account at Synology)?

I'm playing with the DS116 box and something is driving me crazy :)

I will release new uboot for DS116/RS816.

So all old installation methods from raw sectors will be obsolete.
