Hi,

I am using lpc2106 and SPI0 interface for kingston 2gb sd card.

I have the followowing error :

MMC/SD Card Filesystem Test (P:LPC2138 L:EFSL)(##)
efsl LPC2000-port and this Demo-Application
done by Martin Thomas, Kaiserslautern, Germany
CARD init...spiInit for SPI(0)
Unknown error 0x0 (see SanDisk docs p5-13).
Card failed to init, breaking up...

What is wrong with it ?

if I increase the number of retry to (1000 ~ 10000)

in the function
if_getDriveSize
res = sd_getDriveSize( iface, drive_size );
res becomes -1

here is the screen

MMC/SD Card Filesystem Test (P:LPC2138 L:EFSL)(##)
efsl LPC2000-port and this Demo-Application
done by Martin Thomas, Kaiserslautern, Germany
CARD init...spiInit for SPI(0)
Card identified as SD-Card
numsec 1073800832 sizesec 88
Drive Size is 4 Bytes (4294967295 Sectors)
Init done...
failed with -2

is that something related to command timing ?

What version of EFSL are you using?

How have you connected the SD card to the LPC2138? Is
this prototyped wiring, or is it on a PCB? What is the
trace length?

You may have to take a closer look at the functions to
determine why it is returning the values it is. Usually
this error indicates some sort of hardware communication
problem.
