Very slow for NAND #34

Open FrankBoesing opened 2 years ago

FrankBoesing commented 2 years ago

Takes more than 10ms sometimes just to open() a file.

Can confirm that NAND QSPI is slower to open files about 300K:

Added QSPI NOR Flash (16MB)
781 micros
813 micros
780 micros

Added QSPI NAND Flash (256MB)
8765 micros
2937 micros
7075 micros

It does not appear at this point to work of opening multiple files with Franks waveplayer with 3 files but no issue with playing single files from a quick and dirty test.

My last test showed times > 12 milliseconds.
