(09-30-2019, 10:25 AM)z4v4l Wrote: the SPI flash size of all pine boards is 128Mbits or 16MBs. it is intended for using as a firmware home, - uboot in this case, and not everything else. it's small for general usage, it wears out for frequent read/write cycles, and it gives you no advantage of having your cryptographic keys there. it is storage for firmware. there is nothing "unreliable " in it. this whole thread became a mess of confusions.


Computers were meant for number-crunching. The Internet was meant for research. But people did not listen ...


The supplied spi flash supports a min of 100,000 erase cycles per sector. Together with a flash filesystem which spread out writes, I can't imagine that the OP will ever wear out her flash.
