Can I use 18F4620?

strange. Are you sure that your sdcard is in fat32 ? (look at the properties in windows).

Warning, your firmware version doesn’t support the sdcard exchange. So to change the sdcard, you need to switch off the emulator.

Can you try with an smaller sdcard (<512MB) ?

Yes, both are in FAT32.
I have one unit of 16Mb, but windows don´t let me do it. The only option for 16Mb is Fat16.

I´ll try to get a new smaller sdcard. Thanks

yes it seems that there are some bugs with bigger sdcard(>=512MB). 128MB cards are ok.
I will correct this as soon as possible.

Ok Jeff, I need to get another SD card.

How can I do to give FAT32 format? Does Windows let me do it?

If your sdcard is <=32MB, Windows can't format it in FAT32.

can you dump and pack your 512MB and/or 1GB Sdcard and send me the zip ?

don't forget to compile it in release with all optimizations !
( menu Project->Build Options-> Project -> MPLAB C18 -> Categories -> Optimization)

this is not normal! what does the emulator ?

Can you remake an dump of your sdcard ? the last one was not an physical copy but a partition : it was 488MB and not 512MB !

yes, but I didn´t it.
The memory size is usually determined by Windows or another aplication like SDFormatter (I have both and happened the same).

yes for PC you must put an jumper between pins 02 & 06 or 03 & 07 on J3 depending you want an "A:" or an "B:" drive.

J3 is mapped like this :

----------------------
|FloppyConnector |
----------------------
12 11 10 09
08 07 06 05
04 03 02 01
