help
|
||
Many flash memories support erasing small (4096 B) sectors. Depending
|
||
on the usage this feature may provide performance gain in comparison
|
||
to erasing whole blocks (32/64 KiB).
|
||
Changing a small part of the flash's contents is usually faster with
|
||
small sectors. On the other hand erasing should be faster when using
|
||
64 KiB block instead of 16 × 4 KiB sectors.
|
||
|
||
Please note that some tools/drivers/filesystems may not work with
|
||
4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

This enables support for the Quad SPI controller in master mode.

This controller does not support generic SPI. It only supports

SPI NOR.

Enable support for the NXP LPC SPI Flash Interface controller.

SPIFI is a specialized controller for connecting serial SPI
|
||
Flash. Enable this option if you have a device with a SPIFI
|
||
controller and want to access the Flash as a mtd device.
