I had my newly bought second-hand X32 opened and I was curious whether it can use larger SD cards.
The original Behringer SD-card on the i.MX25 board has only 120MiB (“128MB).
According to the i.MX25 datasheet, the SD Card specification 2.0 is supported. That would mean the SDHC standard which goes up to 32GiB.
Now I tried to replace the original card with both - a 32GB (~30GiB) and a 64GB (~61 GiB) cards (i.e. I zeroed the cards first and then wrote the exact image of the original card) and both worked (the original firmware written on those new cards).
However those cards could only have worked in compatibility mode up to a cetrain capacity.
So it would be great to test the maximum capacity in under linux and publish it somewhere.
120MiB seems very little for a reasonable Linux based system.
