Detailed Description ​

cpp
struct flash_info_t;

Static description of the flash device backing a flash0/flash1/... handle.

Filled in by flash_info. All addresses (sector / write addresses passed to flash_erase and flash_write) are absolute and must lie within [startAddress, startAddress + totalSize).
