I am using CoffinOS R54
I tried several microsd card : Samsung, sandisk, from 1go to 128go.

Im connecting the SD card dirrectly without any extender.
Am I missing something ?

Format your SD card on PC to FAT32 fileformat in normal way. Do not use any Amiga tools like HDToolBox, SDMount or Giggledisk.

Make sure you have:

DEVS:sagasd.device
L:fat95
DEVS:DOSDrivers/SD0
DEVS:DOSDrivers/SD0.info

And on Startup-Sequence:

VControl SD=3

Make sure that your DEVS:DOSDrivers/SD0 mountlist uses partition geometry autosense, its contents must be like this:

            FileSystem     = l:fat95
            Unit          = 0
            Flags          = 0
            LowCyl        = 0
            HighCyl        = 0
            Surfaces      = 1
            BlocksPerTrack = 1
            BlockSize      = 512
            Buffers        = 300
            BufMemType    = 1
            BootPri        = 0
            Stacksize      = 4096
            Priority      = 5
            GlobVec        = -1
            DosType        = 0x46415401
            Device        = sagasd.device

If that didn't help, you should check inside the slot to make sure that pins are not bent or damaged.

I know this is off-topic..but I could not help but share this...I have turned my SDNet into an Ethernet port and I am using it to access the internet on my Amiga 500 :D

Hi,
thanks for your help. I tried out what you said. And here is how I test :

0 - inster the SDcard
1 - Boot the amiga
2 - on the top menu, click on mount, I get the following result :
"GiggleDisk : Unable to read block 15 (size 0x800)
3 - Open a shell and type SDDiag, I get the fololowing result :
Debuglevel: 0
SD Card Detection Error: FF

Should the SDDiag return something if the card is no inserted ?

Thanks again for your help.

Hi,
@John, I would be interested in a description of your setup. I want my A500 + Vampire to be able to connect to the network and I am looking for the solutions available.
thanks

Hi,
I tried using an extender and tested the continuity to see if all the pins were OK.
All the continuity tests are fine.
I checked my configuration many times and I tired to use many SD HC cards.
Unfortunatly, I when I use SDDiag, I get SD Card Detection Error: FF.

I there any test that I can do with a multimeter ?

Thanks for your help.

After remembering how and where to add the info (select icon then right click and select icon/information) I added exactly what Simo said and copied the Sdo from System:storage/dosdrivers to System:Devs/dosdrivers, rebooted and it showed up no problem.
 
  Before I did that sddiag was saying it was detected but wouldn't mount, saying it wasn't a dos disk. (I'm running coffin)

Hi,
just a quick update. I sent back the card for repair.
The sd socket was dead (2 out of 10000).
I got the card back working fine :).
