but the sd card is not working, everything works, web ,through bluetooth, via telnet, via usb cable but the sd_card is always not found.

though about remapping the pins, but I guess I wanted to ask first if somebody had a clue

Check the soldering of the SD card socket. We have seen a few poor connections on one of the batches. If you gently push each pin down with a soldering iron, that fixes it.

thanks, gonna check them,

[vascobarbosa]

Checked and rechecked the connections

with the multimeter everything is connected right, and on the right pins

on the web_gui I get always no SD card, and on the computer it works and format in fat32 on a mac osx

This is weird, and sorry about this, but this isnt one of your batchs, had some credits at jlcpcb.com and made them done some boards

I would still suspect the soldering. Those pins can bend up during handling and not solder correctly.

Also see the wiki about formatting the SD card.

fixed it, BAD SD FORMATING

On OSX open the terminal and follow this commands

1) Check what number is the disk

mount

/dev/disk2 on / (hfs, local, journaled) devfs on /dev (devfs, local, nobrowse) /dev/disk3s1 on /Volumes/USB_Disk (msdos, local, nodev, nosuid, noowners) In this case, my disk is disk3. Your disk will most likely be different! Be sure to reference the correct disk - you can and will lose your data if you format the wrong drive!!!

2) Unmount the disk

diskutil unmountDisk disk3

Unmount of all volumes on disk3 was successful

2) Format the drive

sudo newfs_msdos -F 16 /dev/disk3

After a few moments, your drive will format.And it will work
