Started by timo_kuisma April 23, 2007
Hi,

What meaning the "Unknown error 0xFF".

I use Trancended card 512MB with my MCB2140 board (NXP 2148 processor)

terminal window says next:

efsl LPC2000-port and this Demo-Application

Dear Timo,
Sorry,
You will need a MMC card reader. Insert the card reader (usually USB) in PC.
Also insert the MMC card in Card Reader.
In window it will be recognized as Removable Disk.
Right click on 'Removable Disk' and you will get format option.
Use FAT file system.
EFSL format (mkfs_makevfat) some how does not work properly. Otherwise EFSL
is GREAT.
