Problems formatting the SD card

[DenaFrancis]

Hi, I have been trying to format the SD card so that I can begin building the ethoscope. I am a biologist, so not much coding experience.

I am trying to format my SD card on a Mac (macOS Mojave 10.14.6)

I am using a card reader hooked up to the computer, and the SD card adapter is on the unlocked position. My SD card is a Samsung Evo 32GB.

This is what the terminal looks like, its a modified archlinux script that I am following from your manual: disk2 is where the SD card is on my computer. Deannes-MBP:~ dena$ SD_CARD=/dev/disk2 Deannes-MBP:~ dena$ echo "o p n p 1 +100M t c n p 2 w"| fdisk $SD_CARD fdisk: /dev/disk2: Permission denied I also tried this to have a look:

ls -l /dev/disk2 brw-r----- 1 root operator 1, 9 1 Mar 16:14 /dev/disk2s1 Not sure if it helps.

I have looked at other posts/problems online, and I have tried to blow into the card reader (someone said that it helped). But it didn't do anything.

When I look at sharing and permissions for the SD card, it says you have custom access. I have asked others online to help with this issue, but the answers were complicated and did not result in a successful outcome.

I am not sure what to do since I invested some of my own money for the parts and would like to proceed with building this. Thanks

Hi, not much of a mac user, but most likely you need admin (supersuser) rights to format your card (https://support.apple.com/en-us/HT202035). Try opening a superuser session $ sudo su. BE VERY CAREFUL then. Especially ensure /dev/disk2 is indeed your sd card and not another drive (that you will break).

Hi Quintin, Yes, I made sure that disk2 is the right one by looking at diskutil list and it had the right size and name. I tried that and this is what I got:

SD_CARD=/dev/disk2 Deannes-MBP:~ dena$ echo "o

p n p 1 +100M t c n p 2 w"|sudo fdisk $SD_CARD Password: Disk: /dev/disk2 geometry: 3891/255/63 [62521344 sectors] Signature: 0xAA55 Starting Ending

: id cyl hd sec - cyl hd sec [ start - size]

Does this look right to you and should I proceed with the rest of the code? If I can. I am not sure that terminal on Mac has the ability to execute some of the mkfs.vfat code. Thanks for your help, Dena

Please do not do this. Use instructions provided on the ethoscope manual online: https://qgeissmann.gitbooks.io/ethoscope-manual/building-and-installation/ethoscope-software.html

You should burn the SD card using balena-etcher and it will be ready to go.

Hi Dr Gilestro,

I find that balena-etcher doesn’t support .tar.gz files. I got this message when I tried to drop the ethos cope image file

/Users/dena/Downloads/ethoscope_core_files (1)/ethoscope_os_20160721.tar.gz is not a supported image type

Sorry about that, seems that it's more complicated for me? Or I am not doing something correctly. I went onto their GitHub site and asked about this issue. But they haven’t responded yet.

Thanks, Dena

You are not supposed to burn that file. Just follow the instructions on the online manual, verbatim.

The SD image you need to download is linked in the manual (it's this one)

[DenaFrancis]

Okay, thank you. I was using the older version of the manual then.
