My too kangaroo pesos worth
I have read on here that the fast samsung chips dont support HDMI. Would there be available a separate 'chip' to put on the board to make HDMI work with a samsung chip. The speed bump with a rockchip just not enough, going back to a 2 core 'main' chip is almost a regression. $20 for the chip, not much of a chip.
Seeing that you will include sata drives, there is no need for emmc connection, put the money you save into the more expensive sata interface I have read about on here.
As a average user I have never heard of emmc or seen the cards in a computer shop.
Would you be able to get sata cables only 5 inches long made for the N1.
Do away with the piddley micro sd card and replace it with a SD slot, stand it on its side if you say there is not enough room, the xu4 has the usb2 standing on its side.
Is the insidious flashing blue light going to be changed to a blue light showing hard drive activity like on a real computer. I turn my xu4 away from me so I dont see the flashing going all the time. I would rather have a light showing hard drive activity so I can see if something going on when it should not be going on when I am on the net.
I dont have a problem with $110, more if the chip was faster. At the moment the speed bump is not high enough.

Linux support for all other SOCs is garbage, and they (likely) cost more due to included modems etc typically not used on SBCs.

emmc is better than sd due to ssd like features (trim, wear leveling, etc), booting from ssd has not yet been achieved on the N1, and costs more due to the SPI Boot flash.

micro sd cards are more reliable than SD slots with adapters for micro sd cards (learned from rpi), which are popular in phones.

you can make the blue light do whatever you want with /sys/class/leds/blue:heartbeat like just turn it off;
Code: Select all
/bin/echo -n none > /sys/class/leds/blue\:heartbeat/trigger

Not to say actual SD cards are less reliable, just that people will certainly use micro SD adapters which are usually not good.

Want to blink the LED with hard drive activity:

*note (needs sysstat package installed)

Code: Select all
#!/bin/bash
iostat -z -d 3 sda | sed -u -e '1d' -e 's/Device.*/none/' -e 's/sd.*/heartbeat/' -e '/^$/d' > /sys/class/leds/blue\[emoji813]beat/trigger &

In addition to the blue LED that can be configured, there is also a red SATA activity LED.

I was just speaking on the current generation hardware, I didn't know that about the N1 since all my drives are tied up.

I actually prefer having the eMMC as the primary OS device because it can just stay where it is and the OS is untouched. SATA devices are more naturally swapped / replaced and can be had in much larger sizes, so they seem better suited to data storage. Ideally I'll never use the SD card slot, but it costs so little to have there and it might be convenient since they are cheap and tend to be lying around when you need them.

As for the 2+4 cores... sure 4+4 would be more compute, but the six are still a performance upgrade from the eight in the XU4 series plus they're ARMv8 and the board has 4GB RAM. That's a substantial enough win for me, even before I contemplate the GPU.

just stick to the SSD, dont need 2 interfaces whatever with the same features.

and costs more due to the SPI Boot flash
seems like I have to read up on SPI boot flash, its name suggests it might be a place to put files to boot a SSD, seeing that it is on the board already and needed, leave it there.

micro sd cards are more reliable than SD slots with adapters for micro sd cards (learned from rpi), which are popular in phones.
if I had a SD slot on my xu4 I would not be using an adapter for micro sd cards in it, I want the micro sd card to go and never come back. and its adapter My xu4 is not a phone


rooted
I went to install 'sysstat' and it did not work, told me to do a 'sudo apt-get update', it downloaded some stuff and then bogged down again with what looks as the same error message. Gdebi, synaptic, software updater all broken. Looks like a big 'dd' job on the micro sd card coming soon. But I want to try Diet Pi first, I have a thread in Other Os's but nobody has replied.

E: flAbsPath on /var/lib/dpkg/status failed - realpath (2: No such file or directory)
E: Could not open file - open (2: No such file or directory)

Not much joy changing the blue LED

Good idea, Me thinks I will need something I can just click on.

All new laptops these days have a SD slot, some are sold without a CD drives, everything being saved to solid memory.

That's a substantial enough win for me, even before I contemplate the GPU.
Waiting for when all the bugs are ironed out and new comparison graphs posted.

I did a full reinstall of ubuntu and able to install sysstat.
I think we need to start all over with the command but this time without the [emoji813] bit.

[1] 3120
odroid@odroid:~$ bash: /sys/class/leds/blue:beat/trigger: No such file or directory
See how it leaves out the backslash in blue\:beat

In sys/class/leds there is a blue\:heartbeat I dont want to try it, dont want to hose my new install, can I go ahead and change the command line? What should it be

/sys/class/leds/blue\:heartbeat/trigger &

OR /sys/class/leds/blue:heartbeat/trigger &

Here is why I will not use a eMMC card and do not want it on the Next 1.
They use slow speed memory in the smaller capacity cards so that one has to buy a more expensive card to get the faster speeds and they make it progressive so that if one wants the fastest speed then one has to buy the biggest capacity cards. (is the eMMC consortium owned by microsoft, it might as well be)

New 8GB test on XU4 Ubuntu
New 8GB eMMC Red PCB for XU4 model is based on Essencore/AIO's eMMC 5.0 technology.

Sequential speed with “dd” test
dd write : 15.1 MB/s
dd read : 104 MB/s

Here is the fastest card I could buy from the local smart phone flee market, 25% faster. 16GB $14 US Phnom Penh

Its due to it being such a small flash chip. An 8GB NAND chip on any recent process is going to be slow due to not being able to use multiple channels or interleave on the controller.

Same thing happens in SSDs where the 128GB sizes are often far slower than the bigger capacities for the same reason.

It's not a conspiracy, it's just how NAND works unfortunately. It requires large parallelisation for speed and small capacities just don't have the raw dies available to do so.

From the wiki on emmc modules

eMMC Read/Write test on ODROID-C2 HS400 mode
8G Write Samsung 45.4 MB/s Toshiba 21.9 MB/s

New 8GB eMMC test on XU4 Ubuntu
New 8GB eMMC Red PCB for XU4 model is based on Essencore/AIO's eMMC 5.0 technology.
Sequential speed with “dd” test
dd write : 15.1 MB/s
dd read : 104 MB/s

So there are faster 8 GB emmc around, but how much one gets stung for them I dont know.
I am following 'joy' to see if he can get SPi boot working for the Next 1 them emmc wont be needed.
Waiting to see what the Next 1 has.
If it has a flashing blue light and a piddley micro SD card instead of a SD card, I wont be buying one.

The flashing blue light.
I had a go at it, this is what I tried.

iostat -z -d 3 sda | sed -u -e '1d' -e 's/Device.*/none/' -e 's/sd.*/heartbeat/' -e '/^$/d' > /sys/class/leds/blue:heartbeat/trigger &

The blue light went off but when I opened firefox it did not show any activity. Rebooted and the blue light is flashing again. End of experiment, waiting to see what the Next 1 has.

That is meant to be put into a file, then chmod +x it, then run it.

The next odroid will almost certainly have a heartbeat, if you don't like it you are free to pursue other devices.

Your limited knowledge seems to cause you undue stress, it shouldn't since these devices can be a great learning experience.

The heartbeat can be easily turned off:

Code: Select all
echo none | sudo tee /sys/class/leds/blue:heartbeat/trigger

Young mr rooted.

Why then was I not given that information. Besides I dont know how to 'chmod +x' or 'run' it as I have not been to college and spoon fed coding.

if you don't like it you are free to pursue other devices

No, I didnt steal my xu4 from Hardkernel, I bought it from them. I am asking for a howto to change the flashing blue light to show hard drive activity like any other computer.

Your limited knowledge seems to cause you undue stress

'Limited knowledge' agreed, it not compulsory to have been to coding college to use Hardkernel products.
'undue stress' no, I just think it is ridiculous that the blue light that has the capacity to function as a hard drive activity light is set to blink all the time.

The heartbeat can be easily turned off:
echo none | sudo tee /sys/class/leds/blue:heartbeat/trigger

Nope, just want it to work like a real computer.

I hope it's not to late to teach some old dogs new tricks;
rooted its kindly trying to help for free,
oldchap should put forth some minimal effort to learn how to use the (hugely popular and well documented since the 1970s) software,
or at least show gratitude to those who have made the effort to learn and spend free time to teach others.

Apparently you (oldchap)
dont know how

to spell "don't", or use the "Quote" button yet so please look into that as well.

I wasn't trying to be an elitist, I was being realistic.

Every Odroid device I have owned has the heartbeat, I was saying the next will as well. If it bothers you so much why would you purchase?

I also did try to help with your issue, didn't want anything in return. Not even a thank you, if I help that is thanks enough.

Good day.
