Q18. I am having problems communicating with the uSD card?

Ans. Make sure your uSD card supports SPI interface, that is how the on board GOLDELOX-GFX2 processor connects to the uSD card. There are some duplicate cards in the market which fail to work with SPI with accuracy. No specific brands, it is just that they are duplicates of the popular uSD brands.
