Please refresh my memory.

How do zifxify and you boot now? entering commands at u-boot prompt? can you save them? (list them here if you never tried to save them).

I interupt u-boot and enter the following, just to note I dropped starting usb once I had gone over to an HDD install. Also my 20 second rootfs delay was just from testing not actually needed. I use rootfs LABEL but actual device is /dev/md0, lastly my rootfs is ext4 in case it make any difference.

Richard,

Looking at the stock bootcmd

bootspi=run syno_bootargs;sf probe 0 50000000;sf read $loadaddr_kernel $spi_pt_addr_kernel $spi_pt_size_kernel;sf read $loadaddr_rootfs $spi_pt_addr_rootfs $spi_pt_size_rootfs;sf read $loadaddr_dt $spi_pt_addr_dt $spi_pt_size_dt;bootm $loadaddr_kernel $loadaddr_rootfs $loadaddr_dt;

And what we have done to boot Debian:

setenv bootcmd_exec 'echo Booting Debian . . .; run set_bootargs; setenv fdt_skip_update yes; setenv initrd_high 0xffffffff; run load_image; run load_initrd; run load_dtb; bootz $load_image_addr $load_initrd_addr $load_dtb_addr'

setenv bootcmd 'mw 0xf10a2620 0x251;mw 0xf10a2e20 0x251;usb xhciinit; run bootcmd_exec; run bootspi'

You have run these commands too many time. It is safe to save them. So that the next series of test will be more convenient.

Before you save them, copy/paste your current envs to a notepad.

====

And at the u-boot prompt:

setenv ipaddr 192.168.1.250
setenv serverip 192.168.1.2
setenv load_dtb_addr 0x1000000
setenv load_initrd_addr 0x3000000
setenv load_image_addr 0x02000000
setenv load_image 'echo loading zImage from tftpserver ...; tftpboot $load_image_addr zImage'
setenv load_initrd 'echo loading uInitrd from tftpserver ...; tftpboot $load_initrd_addr uInitrd'
setenv load_dtb 'echo loading DTB from tftpserver ...; tftpboot $load_dtb_addr armada-385-synology-rs816-v12.dtb'
setenv set_bootargs 'setenv bootargs "console=ttyS0,115200 root=LABEL=rootfs rootdelay=20 $mtdparts earlyprintk=serial"'
setenv bootcmd_exec 'echo Booting Debian . . .; run set_bootargs; setenv fdt_skip_update yes; setenv initrd_high 0xffffffff; run load_image; run load_initrd; run load_dtb; bootz $load_image_addr $load_initrd_addr $load_dtb_addr'
setenv bootcmd 'mw 0xf10a2620 0x251;mw 0xf10a2e20 0x251;usb xhciinit; run bootcmd_exec; run bootspi'

saveenv

And then boot to Debian

reset

In Debian, reboot, come back to serial console and interrupt countdown, and try booting stock

run bootspi

After you've verified this work for a couple times, I'll look at the address and see how we should repartition the mtds to store kernel files.

@bodhi
All went well until after the

run bootspi

This booted to stock but on returning to try and boot Debian I am getting dropped to an intramfs prompt. i.e. rootfs not found. I will boot back in via a usb drive and see if stock has overwritten something.

Back when I have got to the answer.

Could be the bootargs. Post the log of the boot to Debian if you're not sure.

@bodhi
No, not bootargs I'm afraid.
Booting into stock deleted my rootfs which was /dev/md0 I'm only speculating but stock uses /dev/md0 as its boot device so maybe it was trying to recover it. I have recovered the raid device but was unable to rescue the file system. I will need to start over.

These things happen when you are breaking new ground :)

Will post back when I'm up and running

During testing, the best storage device to house the rootfs is USB. I always assume that is the case (that you are booting with). Sorry, I must have missed where you indicated that you are actually using the HDD RAID to store the rootfs :)

A little bit of a road block :)

The SPI flash size is 8MB. At minimum 1MB must be reserved for u-boot. And the kernel files size are:

zImage
4.5MB
uInitrd
8.3MB
armada-385-synology-rs816.dtb
18K

Looks like we need to work on u-boot a bit more.

I was hoping that we don't need to understand this 2 memory pokes, and the USB 3.0 init, in this stock bootcmd. However, looks like we do need to figure out at least what this command does.

usb xhciinit

On the surface, it looks like the USB 3.0 port on this box is activated by that. Is there one or more USB 3.0 ports availbe outside?

-bodhi
===========================

@bodhi
Two ports available but I confess I'm not sure at the moment if it is needed or not. When I moved over to a HDD install I deleted the following from the env variables you had supplied originally to zifxify

setenv usb_setup 'setenv usbActive 1; setenv usbType 3; usb start;'

And then from the setenv bootcmd_exec

run usb_setup;

In the setenv bootcmd I left the xhciinit bit because I wasn't sure about it.

Maybe I should just try without it and see what happens ?

Richard,

> Maybe I should just try without it and see what

Yes, definitely.

Flash is good when there are plenty to use. But I did not think clearly... We don't care for flash at all, if we can easily make stock u-boot recognize USB and HDD.

The ideal solution is figuring out how to activate USB and HDD in u-boot. If stock u-boot has a command for it, then it's all the better.

Worse case, we'll just poke the GPIOs. We actually know how go about that (we knew what GPIO to poke already).

-bodhi

@bodhi
I thought stock u-boot was unable to load zImage from USB due to lack of ext2ls or ext2load ?

I have reduced the "setenv bootcmd"

From

setenv bootcmd 'mw 0xf10a2620 0x251;mw 0xf10a2e20 0x251;usb xhciinit; run bootcmd_exec; run bootspi'

To

setenv bootcmd 'run bootcmd_exec; run bootspi'

And we boot no problem from HDD (with zImage, uInitrd, DTB via tftp) USB are visible remove / re-insert, mount etc

I can't recall whether this is true, that brain cells have been loaded with diffferent topics :)) seriously. I need to reread the thread to remember. So if you could, verify this by

help

to see the available commands. See if fatload, load, ext2load, ex4load are avaible.

That is expected. u-boot only deals with kernel files. After the kernel has booted, every devices will be available because the kernel is capable of all that.

The issue is whether u-boot can activate USB or HDD to load the kernel files uImage, zImage, uInitrd, DTB... Currently, as we knew, stock u-boot is quite limited, so we can only load kernel files using tftp.

There we go. These commands are capable of booting from storage devices.

So there is no ext2/ext4 load or fatload.

Bummer! this stock u-boot is really too limited. I have to think what should be the best way forward.

I'm typing whilst you are posting, sorry about that, if this is a dead line I'm ready to try again with Sp1 flash if its ok with you ?

Not sure what you meant by SP1? if you meant SPI, it is not feasible because it is to small (some change in booting scheme needed if we use SPI flash).

For now, I think, keep booting with tftp. I need some time to think it through.

Yeah I meant SPI it's been a long day.

I will leave you in peace to think it all through.

Meanwhile just out of curiosity I will see if I can reduce the zImage size by knocking out as many built in modules as I can.

The SPI flash size is 8MB. At minimum 1MB must be reserved for u-boot. And the kernel files size are:

And I missed this post from you altogether!!

Everything you said consequently now falls into place and hopefully now you know I missed the post you don't think I've not been listening.

@bodhi
Hi
I think we were both trying to do too many things at once and on my side with the final post in sight I was guilty of being just too keen to get it done...... lesson learnt!

I haven't tried reducing the zImage / uInitrd size as yet because although its an option it is probably a less desirable solution as it would be an RS816 specific one.

My other thought is can we load zImage into flash on an assumption it loads enough drivers to then use u-boot scsiboot to load the uInitrd direct from the rootfs ?

Richard,

I think it is running well enough now. So the issue of loading kernel from disk can take its time to resolve. Here are the options.

1. Modify stock u-boot to enable ext2load command (my prefered approach).

What I usually do here is rebuild stock u-boot and use kwboot to boot it with UART. See example here. Having a rescue mechanism working while you are messing with the box u-boot is a must do.

And then if kwboot is successful, modify stock u-boot and boot it with UART. Test thoroughly, and then flash it.

2. Loading zImage, uInitrd, and DTB from the HDD raw sector.

This approach is the simple one. We test stock u-boot to see if it can load kernel files from HDD unused sector. Usually, this is best done with an HDD that is not in RAID array. But it will work with RAID too.

See here the Wiki thread for Howto:

The 1st Howto is simpler, where no RAID got involved. The 2nd Howto has some precaution for RAID.

So I think you can try the option 2 first. While I'll see of I can rebuild stock u-boot using their GPL.

I will try to reduce zImage, uInitrd and DTS to below 7mb first as its my preferred option to boot from flash.

Even if I succeed I am happy to test an HDD raw sector boot as others may prefer to go that way especially if you are unable to rebuild stock u-boot.

Richard,

Sure. But the small uInitrd is not useful. You could squeeze them all in about 7MB, and in the future find that you cannot install new module :)

My goal always has been to make it possible to run a full blown Debian system on disk.

RS816 fan speed control

The fans are all pre-configured in @bodhi upcoming 5.1.x rootfs
To control the fan speed on this box you can install Debian fancontrol.

To install

# apt-get install fancontrol

To configure

# pwmconfig

Or if you prefer download the attached fancontrol config file and install it to /etc

Then start the fan control daemon

# service fancontrol start

Very happy to test anything you ask me to in the interest of achieving your goal and generally helping others get this box up and running.

I will see how "close to the wire" I am with my attempts to reduce size if too close I will drop my preferred option.
