Smart card 64 MB v. 128 MB

Smart card 64 MB v. 128 MB

[Ken Offer]

Hello all,

Does anyone know why a nand-driver which works for a 64 MB smart card 
would NOT work for a 128 MB smart card?  I've checked the data sheets 
and the two devices look very similar (same block size, same ecc size, 
same 22-pads, etc.)  My driver mounts the device just fine but when I 
try to erase I get I/O errors.  I'm going to look into the software 
side of this but I thought I'd consult the group to find if there are 
any hardware issues.

Thanks!

Should work with 128MB.

Which device & manufacturer ID is displayed, when you mount your device
? There should be a output: NAND device: Manufacturer ID .............
