Homatics Box R 4K Plus

Help & Support Hardware
6222

I can’t test CE-NG anymore but I can attest similar speeds on CE-NO, at least with the SanDisk on my DuneHD BoxR 4K.

I love hdparm as a tool but definitely not for benchmarks. 3 seconds is way to short to see anything useful and there’s no way to increase the timing to have longer runs. I tend to prefer dd + pv as it allows longer reads so we can see if it remains constant or jumps a bit up and down.

$ dd if=/dev/sda count=6291456 status=none | pv -W > /dev/null
3.00GiB 0:00:27 [ 112MiB/s] [ ... <=> ... ]

and it often reflects real world experience, for contiguous linear reads of big files of course. Random reads are another story :slight_smile:

I doubt it, usually the larger capacity drives of the same line are as fast or faster than the smaller capacity drives. My guess is that USB drives with +200MB/s read rates rely on some feature absent in the 4.9 kernel USB stack.

So I got curious, and got this result:

CoreELEC:~ # dd if=/dev/sda count=6291456 status=none | pv -W > /dev/null
-sh: pv: command not found

Am I doing something wrong, or CE NG doesn’t support this?

Speed test:

It seems pv is not available on CE-NG so remove it from the command line like this :

dd if=/dev/sda of=/dev/null count=6291456

Since we don’t have the pipe anymore, we must specify where to send the data read by dd which is still /dev/null

pv measures the flow passing through it in real time and without it, you’ll have to wait until dd finishes to get the average transfer speed statistics. Remove count=### to read the whole device but it provides little benefit as there’s almost no variation between the start and the end of a USB flash drive like on rotating HDDs

At the end of the day, all this didn’t even matter. I spent an hour trying to boot off the SanDisk and never got it working. No matter what I did to try to get it going, it just kept boot looping.

So I guess I prefer a slower drive that works than a faster one that does nothing!

Does anybody know if it’s still possible to move CE’s data to EMMC if the Homatics is updated to ATV 14? I updated to the new 14.8.7475 today, but when I now run the “mount /dev/userdata /media/data“ command, I get an error:

mount: /var/media/data: wrong fs type, bad option, bad superblock on /dev/userdata, missing codepage or helper program, or other error.

EDIT: Using CE-NG 21.3 because of DV FEL support.

My understanding is that with ATV 14, you can’t move it to EMMC.

Correct info. Android TV uses a different EMMC format on the SEI804’s (like the Homatics)

6232

Use NO. The other versions are EOL

6234

Rocktek G2 Since updating the ATV to version 14.8.7475, I can no longer turn on the CE via IR. Is there a solution?

But Android can be?

6236

yes via BT

6237

Turn on from off? Was IR installed by you as mine(i think) doesn’t have one.

6238

That’s right, I installed IR, for CE but since the new update to 14.8.7475, I can’t turn it on anymore.
When I turn it off, everything shuts down—including the IR sensor—so I can’t turn it back on.

On Android, with the Rocktek G2, when you turn it off, the red LED turns on, which wasn’t the case with version 3717

6239

Was it easy to install? I use CEC so when I switch to that input it turns on from suspend.

6240

I am using CEC from TV to turn of my Ugoos AM9

6241

It should work on the AM9 even without CEC

6242

Yes Its true,
also my Homatics cannot be turned on anymore via IR.
They f.cked up the IR wake up with this forced ATV update I think..
