SIO2SD Dead

[flashjazzcat]

Need some help. I fired up the system this morning (testing Diamond GOS) with SIO2SD hooked up as drive B (SIO2IDE is drive A), and all SIO2SD appears kaput. The LCD display comes up with a row of blocks on the top line, and only the green LCD lights up. This is a real pain since I have to take the lid off the Atari now and remove the CF card from the SIO2IDE to transfer anything from the PC. What can be wrong with SIO2IDE? It was working fine last night. It seems as I get one thing fixed up, another breaks...

Hi!

 

Need some help. I fired up the system this morning (testing Diamond GOS) with SIO2SD hooked up as drive B (SIO2IDE is drive A), and all SIO2SD appears kaput. The LCD display comes up with a row of blocks on the top line, and only the green LCD lights up.

Most certainly the Atmel flash ROM was corrupted/erased and you need to re-flash it. You need an Atmel programming cable (a simple parallel port cable will do) for this, re-flashing from the SD card won't work.

 

While you're at it, change the low fuse byte to 0x3f (instead of 0xff) to enable the brownout detector.

 

Christoph (HardwareDoc) and Bernd (BigBen) from ABBUC reported a similar problem, after enabling the brownout detector this issue didn't show up again.

 

so long,

OK - Thanks for the quick reply. Is there an on-line guide to how to go about this?

I'm using avrdude under Linux and built the simple parallel cable ("BSD") as described on the avrdude website.

 

Flashing the SIO2SD then is quite simple:

avrdude -p m32 -c bsd -U flash:w:sio2sd_all.bin -U lfuse:w:0x3f:m -U hfuse:w:0xc3:m

Thanks for the links. Looks like an interesting project building the programmer, at least when I have more time. Is there anyone in the UK who can do this if I send them the chip? Imagine knowing that you were instrumental in helping to get The Last Word 3.0 released on time!
