BMD has no way to control the manufacture of SD cards and there's no business case for them to subsidize a manufacturer to make compatible cards.
BMD has control over FPGA, which is what the BMPCC consists of. And only BMD has the source codes of it. This is where the error is to be found and rectified and not by third-party manufacturers.
Otherwise please release the source codes.
If it is a hardware problem, please name the problem exactly. BMD did not express itself objectively, so you don't know what the real problem is. Referring to the third is not a solution. Everyone knows that Sony had exactly the same problem and was solved by firmware. So this serves as a decisive weight for credibility?
And here again: Sony had EXACTLY the same problem. It's not true that the problem was a different one. Because the same cards that didn't work at Sony didn't work at BMPCC, BMMCC, VideoAssist either.
That said, the BMPCC is not the greatest choice for long-form work. You'd typically be using a camera that records h.264.
What is told here is actually not to be taken seriously.
@Didier, you're right about everything you write.
BMD should finally react.
Has anyone tested (the affected SD cards that are not recognized) with another BMPCC firmware?
Maybe the cards work with a bit older firmware, 1.6.x and 1.5.x, which you can't find on the BMD side since some time?
