You can maybe try to revert this commit in 5.0 to see if the problem disappears. https://lkml.org/lkml/2018/12/6/746

I know it can have a big impact on which cards are able to be detected (or tuned) at boot.
Unfortunately I don't have physical access to the affected C2. I seem to remember there was an entry that could be made to boot.txt or boot.ini that could adjust the clock of the emmc? Not sure if this is even an option in mainline uboot (or perhaps my memory is off)

This again? When are they gonna stop fucking with the clock phase? It breaks things every single time.
Yes I know its a pain as it breaks boot :( and may even leads to data corruption via io errors which I seen last time I had issue in 4.x

Appears different boards using the emmc driver like to *work* with different clock phases and there is no 1 setting fits all. I will try to test Odroid C2 on 5.0 soon and provide feedback to Jerome on the almlogic mailing list. Other user has reported a similar issue on a S905 TV box.

The problem does not occur on 5.0-rc6 and the Odroid N2 which uses the same driver but I will doing more testing here to confirm as well. Maybe the timing config can be placed into the device tree and be board specific.

Hi,

Is there someone who has already used hardware video decoding with ffmpeg, using a C2 with the mainline kernel? (4.19.20-meson64 #5.75 SMP PREEMPT Fri Feb 8 10:08:40 CET 2019 aarch64 aarch64 aarch64 GNU/Linux)

These are the tests I did:

ffmpeg -c:v h264_v4l2m2m -i Sintel.2010.720p.mkv -an -vf fps=1 -f image2 -strftime 1 "/dev/shm/p_%S.jpg" -> Working well

ffmpeg -stimeout 5000000 -c:v h264_v4l2m2m -i rtsp://192.168.1.31/11 -an -vf fps=1 -f image2 -strftime 1 "/dev/shm/p_%S.jpg" -> Not working at all! (hardware decoding through a rtsp stream)
I got theses sort of errors and nothting is recorded:
[Parsed_fps_0 @ 0xaaaadbc668a0] Discarding initial frame(s) with no timestamp.

ffmpeg was installed through apt, and not compiled.

Please note that I already asked this question on the armbian forum too. No awsers yet....

Thx for your help

scpcom's release is probably the easiest and best to get started on ubuntu viewtopic.php?f=135&t=22717&start=950#p241098

Lots of changes are still happening in the video decoder department so im not sure exactly where it is at currently.

Hi @Brad, Thx for your help.

I did a try with your suggestion, and revert back to 4.19.8, using all patches from @scpcom. And got the same result!
The hardware video decoder is properly recognized but the output is empty.

This is the output I got with the @spcom image:

Does anyone have any advice for modifying the device tree or creating device tree overlays?

I would like to connect an LED momentary switch to gpiopower, and the LED on the switch to /gpio_leds/hearbeat. I have two issues with this on the mainline kernel:
  • The heartbeat led had been moved to /leds/blue, but running a ftdget /leds/blue gpios returns: 46 13 1 instead of 37 13 1 according to the wiki page: Alternative Heartbeat LED. The wiki is also a bit unclear as to how to find the correct pin bank number for the gpios, in one place it states most of the J2 pins are on pin bank #19, but further on in the example the led is connected to pin bank #96.
If anyone is able to assist me with how to add gpio_keypad into the device tree, and/or how to determine the correct pin bank to move the heartbeat gpios, it would be greatly appreciated. Thanks!

We have tried removing and reinstalling uboot-odroid-mainline in a chroot, but the only thing that seems to get the the C2 to boot again is downgrading to linux-aarch64-4.20. I am baffled since my C2 seemed to upgrade without issue, the hardware and software loadout are nearly identical.

Thanks Brad. Can you post again when this change has made it into an rc? I'm not entirely sure how to track that and other readers might not be either.

Yes will do. It is still under some further discussion at the moment in the mailing lists. Looks like it might bring some added performance boosts as a bonus when it arrives

Anyone else having weird issues lately where an ssh connection to an odroid C2 running the mainline kernel just hangs for a while? As long as the connection is fairly active it doesn't happen, but if it's sitting idle for even like 30 seconds it seem to hang. I'm gonna downgrade to 3.16 and see if it's the kernel or not.

edit: Yes, downgrading the kernel seems to have made the issue go away. Is anyone else experiencing this?

happens to me over the internet. if i'm connected via LAN, it does not disconnect.
if you are using putty, enable the keep alive in the connection section.. 30 seconds works ok

Still having problems, and I'm on a LAN. The connection "freezes" if there is no traffic over it for ~30 seconds, but if you press enter a few times it will eventually come back (10+ seconds later). Not connecting from putty - this is the ssh client that comes with macOS (OpenSSH_7.9p1, LibreSSL 2.7.3).

Oddly, if I first ssh into another non-Odroid board and then from there into the C2, I don't have this problem. The intermediate board is running a 4.9.x kernel and has OpenSSH_8.0p1, OpenSSL 1.1.1b. So on the face of it that would suggest there's some ssh keepalive configuration mismatch between the default settings on latest macOS and on Arch Linux. But if that's the case, then why do I only have this problem when using the mainline kernel and not the Hardkernel 3.16.x kernel?

(Also, why use putty, doesn't even Windows come with openssh now?)

Has anyone had trouble upgrading to 5.0? I pulled the new Arch mainline package today and my C2 didn't survive a reboot. Haven't dug into what happened yet, since I have to pull the eMMC to find out. I don't get HDMI output on the mainline kernels.
Yes and no, I have a C2, running the Arch Linux mainline kernel, it upgraded from 4.20 > 5.0 without issue. However, my brother is running a nearly identical setup to mine, when he upgraded to 5.0 his C2 failed to boot. looking at the serial console the last few lines read:

What colour eMMC are you using? rarecoil, you too?
I'm using one of Ameridroid's generic eMMC cards:

https://ameridroid.com/products/emmc-5-1-module-blank

I bet this is the problem. I haven't attempted this again since my C2 is in use as a home server + haven't had time to mess with it.

If you wish to contact our support department at orders@ameridroid.com, we will exchange the eMMC with an official HK one for the cost of shipping and price difference. That will remove the eMMC as a question regarding compatibility.

I have a working 16Gb black emmc and a non working 64Gb orange emmc. I have been trying some newer patches from Jerome for the orange but no luck as yet, I will do some more testing for this on 5.2-rc when it's out as it has a few more changes. The 64Gb is only new and works on N2 (mainline variant) fine and also c2+n2 hardkernel.

Not sure if it might have worked on older mainline version (C2) as yet.

Seems you're out of stock on red-box HK 64GB eMMC, which would match my generic one.

I just ordered a 128GB C2 HK eMMC from you guys. No big deal. I'll take the upgrade anyway since I could use more eMMC scratch space; I was doing some analysis on my C2 this week and had to dump everything on a large MicroSD which was... slow, to say the least.

Does anyone know who is the kernel developer working on meson MMC stuff? If the Ameridroid eMMC turns out to be the issue, I will donate it to the kernel developer as test hardware.

About running HS400 (DDR 8-Bit + 200MHz), my suggestions are....

1. Solid eMMC chip on Odroid-C2 PCB directly to decrease the data path delay of eMMC I/O, and avoid the contact issue of eMMC adapter. It could improve the quality of eMMC I/O signals.
2. eMMC Host should fine turn the input delay (internal clock for sampling RX data, or delay the RX data without fixed clock) during executing turning operation (send CMD21)
In S905 datasheet, you could find some register of like
SD_EMMC_CLOCK 0x0
[23:20] Cfg_rx_delay
[13:12] Cfg_rx_phase
SD_EMMC_DELAY 0x4 (I don't know it's for input data or output data or both)
SD_EMMC_ADJUST 0x8
SD_EMMC_CALOUT 0x10

3. Other more difficult ways are like
--Using high bandwidth oscilloscope to check the interface timing (if you could probe the eMMC I/O on Odroid-C2),
--Ask eMMC chip vendor to configure their output delay for you

About how to switch signaling voltage between 3.3V/1.8V/1.2V, unfortunately, the datasheet of S905 (v1.1.4) doesn't explain it.
(BTW, I didn't buy Odroid-C2.)

But if that's the case, then why do I only have this problem when using the mainline kernel and not the Hardkernel 3.16.x kernel?

(Also, why use putty, doesn't even Windows come with openssh now?)
ye its very odd, i dont remember this happening before.. and the thing that it happens to me over internet but no on lan... geez that weird

win10 ssh messes up the window whenever some app (like midnight commander, which i use a lot) changes background colors.. they never go back to black..
and i have been using putty since i can remember, so... old habits die hard

After installing Ubuntu 18.04 LTS i followed the guide: http://seafile.servator.de/sbc/odroid/n ... nstall.txt.
System reboots, but now i cannot login with "user(pw)": root (odroid) or odroid(odroid).
any ideas what pw can be.
