6.6. MTD SPI driver for ST M25Pxx (and similar) serial flash chips¶
Additionally to the Linux bindings in
the barebox driver has the following optional properties:
- use-large-blocks : Use large blocks rather than the 4K blocks some devices
- support. 4K erase blocks do not work with UBIFS which needs a minimum erase block size of 15360 bytes. Also bigger sectors are faster to erase.
