| 03:04 | cbxbiker61 | just ran a back to back iozone benchmark between sandisk extreme plus 32G (gold) and sandisk ultra 32G (silver) |
| 03:04 | cbxbiker61 | identical setups, freshly untarred filesystem |

| 03:05 | cbxbiker61 | that's 4k on the extreme plus |

| 03:06 | cbxbiker61 | that's 4k on the sandisk ultra |
| 03:07 | cbxbiker61 | you can see there is a significant bump in 4k performance, i'd definately get the extreme plus if you can afford it |
| 11:16 | rabeeh_ | cbxbiker61: which filesystem are you running on? ext4? f2fs |
| 11:18 | cbxbiker61 | f2fs, 3.10.39 |
| 11:22 | cbxbiker61 | rabeeh_, do we have stable patches for cubox-i that enable some of the higher speed sd modes yet? |
| 11:25 | rabeeh | cbxbiker61: the patches are here; but requires hardware modifications |
| 11:26 | cbxbiker61 | difficult hardware mods? or something i could pull off with a small soldering iron? |
| 11:28 | cbxbiker61 | i'm doing a patch that enable multi-thread compression programs in tar when it detects a multi-core system |
| 11:29 | cbxbiker61 | most of the compression programs have multi-core versions now, and i want it to be detected at runtime |
| 11:29 | rabeeh | cbxbiker61: the modifications are two types; one that is easy and will enable DDR50 (and probably SDR104) only on powerup |
| 11:29 | rabeeh | second will add a p-channel transistor that is required to power cycle the sd card |
| 11:30 | rabeeh | the reason for the second one is that there seems to be an issue when soft resetting the system and getting the sd card to identify itself as uhs-1 capable |
| 11:30 | rabeeh | that was reproduced on two different sd cards, samsung and sandisk |
| 11:31 | rabeeh | the first patch is really simple; cut a trace and rewire; i'll send you the description by email. |
| 11:31 | cbxbiker61 | ok, sounds good |
| 11:47 | rabeeh | cbxbiker61: sent that to you |
| 11:47 | cbxbiker61 | thanks |
| 11:47 | rabeeh | you need to cut a wire; rewrite the sd card supply and then remove the 'no1-8-v' from the kernel DT file |
| 11:47 | rabeeh | this will get you DDR50 working; just 'dmesg | grep DDR50' on the boot and you should see it. |
| 11:48 | rabeeh | notice again that 'reboot' or any other soft reboot will make the SD cards that we have tested to report SDXC only |
| 11:49 | cbxbiker61 | ok, i dont have a problem adding the transistor as long as i have reasonable sized solder points |
| 12:03 | rabeeh | cbxbiker61: there is no place for the p-channel transistor on the board; thus lots of wire cutting |
| 12:03 | rabeeh | HB will have that built-in |
| 12:03 | cbxbiker61 | ok |
| 13:09 | erikohman | Hi, i have a cubox i4pro and try to get samba to work. Does it exist any good "how to's" like in the raspberry pi community? |
| 13:10 | erikohman | and does it exist any xbmc distro where CEC work? thanks :) |
| 13:10 | cbxbiker61 | samba should just work as per any samba guides |
| 13:11 | erikohman | what linux distro should i use? arch och debian |
| 13:12 | cbxbiker61 | i can't say....i have my own distro and i don't know which other distro is best supported on cubox-i, maybe someone else can comment |
| 13:18 | cbxbiker61 | i guess i could say that i like the way that arch does thing, much more closely to the way my system works |
