PINE64 - General Discussion on Quartz64

DDC Support / DesignWare HDMI Controller

Mon, 14 Oct 2024 12:31:08 +0000

Hi there,

it seems that by default only the internal I2C-controller of the DesignWare HDMI controller is enabled. However, it is known that this is sufficient to retrieve the EDID, but the internal I2C controller of the HDMI module is not suitable for full DDC support, see the discussion here:

https://patchwork.kernel.org/project/dri.../#22771979

However, the driver supports using an external I2C-controller, and reading through the schematics for the Quartz64 model A

https://files.pine64.org/doc/quartz64/Qu...210427.pdf

it shows that the I2C-5 pins are even connected to the HDMI plug (search for HDMITX). So things are correctly setup in hardware, what is missing are the proper settings in the device tree. This can be cured by the attached device-tree overlay. The overlay

enables the controller for i2c-5 with the m1 pin configuration (see schematics for the board)
removes the respective pins from the pin-control entry of the HDMI controller to resolve conflicts
adds "ddc-i2c-bus = <&i2c5>;" to the hdmi controller section

Afterwards DDC just works, on Linux "ddcutil detect" will succeed and, e.g., "ddcui" can be used to control the settings with a GUI.

How to reengage PCIe when reapplying power?

Sun, 06 Oct 2024 23:11:55 +0000

Hi there,

thanks for this nice board. So far I have a working NAS setup with a Quartz64 model A, using the Startech 8 port SATA board plugged into the PCIe slot.

I am now trying to switch between battery powered "low power" mode and the "regular" 12V power supply. I know from reading the Wiki

https://wiki.pine64.org/wiki/Quartz64_Mo..._a_battery

that the PCIe slot is powerd down while using the battery.

Now comes the challenge: how to properly reengage the PCIe slot when switching back from battery mode to the "fully powered" mode?

So far I tried:

- unmount all drives before disconnecting the 12V main power supply
- remove the PCIe slot via "echo 1 > /sys/bus/pci/devices/0000:00:00.0/remove"
- switch off the 12V supply

So far so good. The system keeps on running, the NIC is still powered, everything seems to work as expected, I am still logged in via ssh after disconnecting the 12V supply.

Now, when I reengage the 12V supply, I try to resurrect the PCIe bus via

echo 1 > /sys/bus/pci/rescan

This makes the PCEe bridge reappear. But the SATA-controller plugged into the slot is not reinitialized. I tried also

echo 1 > /sys/devices/platform/3c0000000.pcie/pci0000\:00/pci_bus/0000\:00/rescan

But this does not seem to have an effect. The output of "lspci" still only reads:

root@nas:~# lspci
00:00.0 PCI bridge: Rockchip Electronics Co., Ltd RK3568 Remote Signal Processor (rev 01)

but should be something like this

root@nas:~# lspci
00:00.0 PCI bridge: Rockchip Electronics Co., Ltd RK3568 Remote Signal Processor (rev 01)
01:00.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch
02:01.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch
02:02.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch
02:03.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch
02:04.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch
03:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)
42:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)
81:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)
c0:00.0 SATA controller: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller (rev 02)

I would be kind of cool (for power-saving reasons) if it would be possible to dynamically switch between battery and 12V main power supply. Is there any knowledge in this forum how to achieve this?

Kind thanks in advance for any comments, best

Quartz64 seeming died

Sat, 20 Jan 2024 01:29:18 +0000

So I was playing around with my Quartz64 board and I did a reboot and it didn't come back up. All I get now is the power led but there is not activity on the display or network. I don't know what I did but I'm hoping it didn't just randomly die.

Has anyone had something like this happen? If so, how did you fix it? I really hope the answer isn't to buy another one.

SOQuartz NPU

Wed, 22 Nov 2023 02:01:44 +0000

I've been wondering about the Neural Processing Unit on the SOQuartz, but can't seem to find any documentation about it from a quick look. What can it do, and what software is available that supports it?

Quartz64B eMMC boot failure

Tue, 14 Nov 2023 20:16:30 +0000

I installed DietPi from https://dietpi.com/downloads/images/Diet...orm.img.xz onto a 32GB SD card and it booted successfully. The system had a 32GB eMMC module installed so using the instructions found in https://dietpi.com/blog/?p=1236 I copied the running SD card image to the eMMC.

The system will not boot from the eMMC but gets a Kernel Panic. Inserting the SD card doesn't help. If I remove the eMMC module, I can boot from the SD card again.

Obviously, the method I used to copy the system from the SD card to the eMMC was wrong. First, I'd like to erase the eMMC module so I can get back to a running system with the eMMC installed. Second, I need better instructions on how to successfully install DietPi on eMMC.

Quartz64 model a neither booting nor resetting without pressing reset button

Mon, 21 Aug 2023 21:39:44 +0000

Hi all, i just installed two quartz64 model a sbc, i choose manjaro arm and it runs pretty well , the only thing that fails is that, to boot the board, it needs to mantain the reset button pressed while connecting the dc power jack, after a while it loads the os.

If not doing so it doesn't boot. So i cannot reboot the board remotely (so it cannot be ran as remote server)

I am using a 64GB sandisk extreme sd (model SDSQXAH-064G-GN6MA ). I have ordered a kingston CANVAS GO PLUS to check if things get better. Also i am thinking if an emmc module will be better, so maybe i'll get a okdo emmc module ( https://es.rs-online.com/web/p/complemen...ck/2565008 ).
What do you think? Has anyone this same boot problems?
Thanks !

Thoughts on repairs for a Quartz64-B

Wed, 02 Aug 2023 05:37:56 +0000

Hello,
I purchased new a Quartz64-b, and eventually found out that the Ethernet is faulty. ...after the 30 days warranty.
(I'm not a complete newb with SBC, but I got it, then ordered a Uart dongle later on, and that took its time to arrive and 30 days later...)

The errors for reference:
[ 163.788898] rk_gmac-dwmac fe010000.ethernet end0: PHY [stmmac-0:01] driver [RTL8211F Gigabit Ethernet] (irq=POLL)

[ 166.513886] rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma

So, a cautionary tale maybe? What to do?

Either: 1) wait - it may be a firmware issue. It hasn't been confirmed.
2) repair it somehow? That seems very difficult.
3) work around it. Wifi is working and a USB Eth --provided its NOT in the USB3 socket.

So, be careful. The quality control may not be there entirely. I don't know.
When you get it in the mail - test it ASAP, but then again you may not know all the faults with the device before the 30days is up .
Would I buy one again? ....probably not.

Li-Pol QUARTZ64 Model-B vs Model-A

Thu, 13 Jul 2023 21:24:01 +0000

Hi
As a new raspberry->pine64 I'm lost in all model options and I find it confusing.
I think a comparison sheet would/table would bring benefit to all buyers to see which on is the most modern which on lack what.

For QUARTZ64 Model-B I found info it can handle 3-pin li-po charging with temp. sensing.

The page for Model-B does not mention it.
So does it mean it's gone in model B?

Figuring out a NAS setup around a Quartz64A

Sun, 25 Jun 2023 02:04:51 +0000

Hello,

For the past few weeks, I've been trying to theorise a setup for a NAS around a Quartz64 A SBC, and would like to get some feedback!

I'd like to run a 2×4TB hard drive configuration (with data replication), mostly for a Nextcloud home server.
I'm thinking of getting the PCIe to SATA III card, and powering the drives directly from the board with the power cable for dual SATA drives. To have enough power for all this, I'd use the 12v5a power supply.

I was somewhat inspired by this blog post and would like to know if anyone has done anything similar…? I went for another setup for powering the drives, suggested on the Quartz64 matrix channel, because I don't have a PC power supply laying around, so that set up would be a lot more expensive for me.

I'm not yet sure if I'd go with the 4 or 8 GB model for the Quartz64, so I'd appreciate feedback on that too, if you have a Nextcloud server!

Thanks to anyone for their help or input! I haven't bought anything yet, so I'm open to any suggestion on how to improve this setup

PS: I am from the EU; does anyone know how import stuff works? I've never ordered anything from overseas, is there a way I can figure out an estimate of how much import duties I'll have to pay?

Very slow GbE when receiving, fast sending

Thu, 25 May 2023 15:51:19 +0000

I received my Quartz64 a little while ago and have been experimenting a bit. The network is extremely slow when receiving data, but does the usual 940 Mbit/s full saturation for 1 gigabit when sending. Please see below iperf3 outputs. 10.0.0.201 is my Quartz64 model A and 10.0.0.4 is a pretty powerful amd64 Linux workstation.

Look at all those retransmits! I've verified that the cable and switch port and everything else in the setup are otherwise fine. This happens in both Arch and Plebian. Did I receive a bad board, should I submit an RMA? Or is there something else going on here?

can't get quartz64-A working

Tue, 11 Apr 2023 19:12:44 +0000

Hi,

I've tried to get a quartz64-A up and running with numerous images (manjaro, plebian, gentoo), and I'm not getting any response from it. The power LED comes on and some of the images light the heartbeat LED, but I don't get a video output, my router doesn't detect a new device on the network (I've attached it via ethernet), and I'm not able to get a response from the uart/usb interface (I'm new to uart, so I'm not 100% sure on this point). I've tried booting off a eMMC and microSD. I checked the microSD with badblocks to see if it was corrupt, but it checks out.

Any recommendations?

Query on available OS

Sun, 05 Feb 2023 10:41:40 +0000

Hi guys,

I'm a newbie to Pine64 but have been following with keen interest for several years and have a query regarding the Pine64 single-board computers.

I am exploring the applications of my Raspberry Pi for some time and want to buy another but would prefer to support this community - so, do the single-board computers work the same as a Pi? Would I be able to flash all the same operating systems as a Pi with for example the Raspberry Pi imager?

Kind regards.
