[09:02:06] <Xogium> heya peeps :) I was jusr wondering, are there any so-called modules soled for this board yet ?
[09:02:25] <Xogium> Flash module for SPI, NAND, eMMC
[09:02:33] <Xogium> how does that work ?
[09:03:40] <Xogium> I checked all over the store but didn't find, if there is. Or is it nothing really special ? I'm confused… I have no idea what that flash module looks like
[10:25:55] <Tsvetan> Xogium: these are not released yet
[10:26:05] <Tsvetan> Happy New Year to all!
[10:27:58] <Xogium> Tsvetan: thanks for the answer :) and happy new year
[10:28:21] <Xogium> Tsvetan: but if I understand correctly, they will be sort of removable spi flash/eMMC/nand ?
[10:30:55] <Xogium> trying to understand the idea… I'm blind so I don't have any idea what the board and connector looks like… I generally understand how something is made when I have it in hand for the first time
[15:53:56] <Tsvetan> Xogium: instead to keep 10 different LIME2 boards with just different Flash NAND/eMMC/SPI we decided to put the flash on module and they to be exchangable. You need 8 GB NAND Flash buy base board with this module etc
[15:54:35] <Tsvetan> for the moment we have 5 different A20-OLinuXino-LIME2 just with different flash on them, this is a bit complicated for the production and logistic
[15:55:25] <Xogium> Tsvetan: definitely ! This is very good. So is it a push-pull socket like on micro sd ?
[15:55:49] <Xogium> also allows for easy replacement of dead flash
[18:08:07] <diego71> Xogium: from the photo is phisicaly very different from a sd connector
[18:08:54] <diego71> much more pins at least
[18:11:30] <Xogium> diego71: oh… Hmm maybe flat pins like some use for connecting SoM ?
[18:13:28] <diego71> it's a sort of rectangular male plug, with pins on the 2 opposing sides
[18:14:44] <Xogium> ah
[18:15:03] <Xogium> so you probably just fit them straight down
[18:15:06] <Xogium> nice
[18:15:14] <diego71> so, probably on bottom side of the memory board there is a socket
[18:15:18] <diego71> yes
[18:15:24] <Xogium> cool
[18:15:34] <Xogium> thanks for explaining :)
[18:18:11] <diego71> you're welcome, btw: there are 40 pin
[18:18:53] <Xogium> oh that little ?
[18:18:58] <Xogium> I expected more pins
[18:21:11] <diego71> there is a 8bit bus for data
[18:21:37] <diego71> so 8 pin + 8 gnd and control line for nand / emmc / spi
[18:22:07] <diego71> 8bit bus seems to be multiplexed between emmc and nand
[18:24:37] <Xogium> diego71: makes sense, eMMC is 8 bit bus
