ok before i assume and start chasing different sdcard formats… Ive inserted an 8GB ext4 sdcard into a mangOH green… but i dont see it, as say sdX … so is it ext / msdos /vfat or does it matter? deeper issue is the sdcard ? or controller? cm info Device: WP8548 IMEI: 359377060159869 FSN: LL731400301610 Firmware: SWI9X15Y\_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06 Bootloader: SWI9X15Y\_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06 priIdPn: 9906351 priIdRev: 01.01 skuId: 1103113 and i am finding this in dmesg [9.495009] mmc0: mci-version: 18 [9.504349] mmc0: bam physical base=0x12182000 [9.507767] mmc0: bam virtual base=0xd0374000 [9.512131] sps:BAM 0x12182000 is registered.

Not all sd cards work with mangoh. We provided a couple that worked. You should use the search section of the forum and you will find the post showing the names of the working ones ---

I would recommend thinking of the forum as a knowledge repository that should answer some of the most common questions. If I do a quick search on the forum, this post is relevant to you > [@Micro SD Support on MangOH](http://mangoh.discourse.group/t/micro-sd-support-on-mangoh/91/17): > > Hi Ashish, I have tested with different SD card and below are working good PNY 4GB Strontium 4GB/8GB Samsung 4GB/8GB Thanks This forum is a public forum where the expectation is that community member contribute to the overall growth of the knowledge base so that we all benefit. To answer specifically to your comment, we are planning a website update in Q1 next year, where we will document the SD cards, GPS antennas, other accessories and other support that go with mangoh platform. Usually, we monitor common forum posts and then do tutorials, videos or general website updates. ---

Hi, Has there been any update on the list of SD cards that are now supported? I’m seeing a similar error -110 as the original post on the mangOH Red and am wondering if it’s because I’m using an unsupported microSD.
