The -1000 is a timeout thrown while trying to initialize the card. Inside the safe_spi.spin file, you can find the "PRI read_slow" function. Inside there is a block of clde that looks like this:

if( (cnt - SPI_block_index) > (clkfreq << 2) )
    crash( ERR_CARD_BUSY_TIMEOUT )

That sets the timeout to 4 seconds. If you want to try a much longer timeout, just to see if this card is very slow, change to "(clkfreq << 4)" to make it wait 16 seconds.

Can you try this code with another SD card? Is it possible there are problems with the electrical connections, mixing up pins, etc.?

Thanks for the help Jonathan!

The error of timeout is because the old SDcard, with a new one I have the error -1
The pins are not mixed up, i already see hundred times!! :P

I was looking with a voltimeter all the pins:
WP - 0V (if no protect SDcard to Write)
CD - 0V (if card inside)
IRQ - 3.3V
DO - 2.2v (IS NORMAL?) (to P0)
SCLK - 3.3v (to P1)
DI - 3.3V (to P2)
CS - 3.3V (to P3)
RW - 3.3V

with the obj "fsrw-and-friends-1.7" i have the error "-13"...

any suggestion is welcome!
