I have one problem with store data into flash on my uC LPC1759. I need to save 64 byte data into flash, but when i use IAP-Interface, it takes more than 1 second. Is there a way to make it faster than 1 ms ? It is possible use DMA for copy data from RAM to Flash? Or write data to flash less than 256 Byte ( UM10360 - minimum size - 256 Byte).
