WebSep 20, 2016 · This answer makes a lot of sense. I suggest to check the datasheet and make sure the sectores are unlocked. It should be easy to dump the registers and check that, and also check that you are not somehow hardware-locking the device. Webspi_flash_control_hw (SPI_FLASH_SECTOR_UNPROTECT, 0, NULL); spi_flash_control_hw (SPI_FLASH_4KBLOCK_ERASE, 0, NULL); spi_flash_write This function writes the content of the buffer passed as a parameter to serial flash. The data is written from the memory location specified by the first parameter. This address ranges from 0 to SPI flash size

WebNov 24, 2024 · INTRODUCTION. Spiffs is a file system intended for SPI NOR flash devices on embedded targets. Spiffs is designed with following characteristics in mind: Small (embedded) targets, sparse RAM without heap. Only big areas of data (blocks) can be erased. An erase will reset all bits in block to ones. WebAug 8, 2024 · Serial NOR Flash typically uses the Serial Peripheral Interface (SPI) protocol to interface with the memory controller. To achieve higher throughput, dual SPI and quad SPI interfaces are available. Another feature used in serial NOR Flash to further enhance throughput is Double Data Rate (DDR) signaling.
