16:45 ngochai Hi guys, is there a reason why SDcard get corrupted? we have about 25 hummingboard i2ex having this problem even of a readonly rootfs (Ubuntu 14.04)
22:37 ngochai hi guys, what is the MicroSD controller that hummingboard use?
22:38 Catwich ngochai: what do you mean by controller?
22:38 Catwich its part of the SoC
22:38 Catwich and supposrts sdxc cards up to UHS-1 afaik
22:39 ngochai Catwich, so what's the name?
22:39 ngochai and what's Linux driver/module name for it?
22:41 mk01 DRIVER=sdhci-esdhc-imx
22:41 mk01 OF_NAME=usdhc
22:41 mk01 OF_FULLNAME=/soc/aips-bus@02100000/usdhc@02194000
22:41 mk01 OF_COMPATIBLE_0=fsl,imx6q-usdhc
22:41 mk01 OF_COMPATIBLE_N=1
22:41 mk01 OF_ALIAS_0=mmc0
22:41 mk01 MODALIAS=of:NusdhcTCfsl,imx6q-usdhc
22:42 ngochai mk01, thanks
22:43 mk01 welcome
22:43 mk01 what are the cards you use ?
22:43 mk01 is there any pattern among them ?
22:44 ngochai Sandisk Ultra UHS-I 32GB
22:44 mk01 ok
22:44 mk01 yes
22:45 mk01 axact hit
22:45 ngochai mk01, ???
22:45 mk01 (card causing issues)
22:45 ngochai really, what card should I use then?
22:46 mk01 what kernel you use right now?
22:46 mk01 the 3.14-*****-sr branch ?
22:46 ngochai 3.14.14+
22:46 mk01 upgrade to the new tree
22:47 mk01 there was lot of work done to make those cards work
22:47 ngochai which new tree?
22:47 mk01 https://github.com/SolidRun/linux-fslc
22:49 ngochai is there any better card if I don't want to use the new kernel?
22:55 mk01 personaly
22:55 mk01 I don't have any other UHS cards
22:55 mk01 just those three SanDisks for testing
22:56 mk01 but general reports / feedbacks do speak about sandisks a lot - jnettlet was also mentioning some ultra-mega-special-speedy SAMSUNG cards
22:57 mk01 so perhaps any others are fine (]assumption).
22:57 ngochai so those samsung cards are better than the sandisk?
22:57 mk01 no I mean - problem reports
22:58 mk01 I don't remember other brands being reported (as causing problems)
22:58 ngochai ok, thank you mk01
22:59 mk01 if you would go for the new tree, I run 4,8 and 16GB sandisks - in HB1 - HB2ex boxes
22:59 mk01 and are fine now
23:00 ngochai what's with the new tree, what's fslc by the way?
23:00 mk01 fslc is freescale
23:00 mk01 this is upstream repo - https://github.com/Freescale/linux-fslc
23:01 ngochai ah I see
23:02 mk01 basically it is very much safe to switch as it is the same 3.14 tree, just with many fixes on top of FSL + support for wider portfolio of imx6 devices
23:02 mk01 (so not just solidrun).
23:04 mk01 perhaps
23:04 mk01 you could just merge the drivers/mmc commits on top of your 3.14.14+ you use now
23:04 mk01 +one or two commits in dtb files
23:05 ngochai well that may take a lot of time I imagine
23:06 ngochai compiling linux-fslc now
23:08 mk01 I was looking at the log difference, it is perhaps up to 10 commits
23:09 mk01 from jnettlet and rmk
23:10 mk01 but SolidRun/linux-fslc branch is regularly updated (as LTS kernel) - 3.14.14+ for some time not anymore
23:11 ngochai alright, thanks
23:11 mk01 welcome
