sio2sd error init card

[pancioalbe]

Hi, you're sorry my English.
I built a sio2sd, using an atmega 32a, I programmed the atmega 32a with the last available file.
but if I start the sio2sd it gives me error no sd / mmc card and after a few minutes it gives me error init card.
I have programmed the atmega 32a without setting the fuses that are written on the website, because if I imposed the merges atmega stops.

does sio2sd not see the sd card for a programming or hardware problem?
I tried sd card from 1gb and 4gb card and following a guide on youtube
thank you so much.

I have no crystal ball available, to see the unknown.

 

If I have to guess, I would suspect the SD card reader,

it's connection, or the SPI bus or something like that.

 

But sorry, it's just a guess - and even with photos...

no chance to help.

sd card works, 3.3 regulator works, i changed 3 atmega 32a.
the slopes welter all

touch up all solder connection. re-program atmega make sure security brown out fuse bits are set.

last thing is other chip and transistor, make sure sd card slot is not damaged, is clear, and not dirty..

I changed the controller and the 74hcxxxx but still error.
I have programmed the atmega without setting the fused bits, because if I set the fused bits as written on the site of the sio2sd the atmega crashes, I already tried two atmega that are now blocked. I have programmed without setting the merged bits.
I prepare the sd card with atari folder and Sio2sd.xex files
How should I set the merges?
I program with avrdude and the command is this:

sudo avrdude -c usbasp -p m32 -u -U flash:w:sio2sd_all_v3.0rc5.bin

and this is the command I used to set the fuses

sudo avrdude -c usbasp -p m32 -u -U lfuse:w:0x3F:m -U hfuse:w:0xC3:m flash:w:sio2sd_all_v3.1rc2.bin

 

I have 3 atmega, 2 blocked and one mounted on the sio2sd, how can I do to recover the two locked at'mega, so to do other tests?
thank you

[pancioalbe]

I give the atari and the sio2sd from no sd / mmc card. and remains locked even if I press the keys nothing changes.
when error init card appears, I can enter the sio2sd configuration

[pancioalbe]

I changed pcb, sd docking, 3.3v regulator, capacitance resistances and 75hxxx but it is always error.
I think problem of fuse atmega

I do not know why but it works after giving this command once again
thank you very much for the answers

Try different sd card or older sio2sd firmware. The newest firmware gave me same issues.

 

Some cards are refused.
