`ice_flash.h`

High-level interface for flash I/O. All these functions act on the on-board flash chip. For a generic flash memory I/O, you can see the low-level ice_smem.h

`ICE_FLASH_PAGE_SIZE`

The size of the flash

`void ice_flash_init(void)`

Initialise the SPI1 peripheral, dedicated to flashing the FPGA.

`void ice_flash_read(uint32_t addr, uint8_t *data, size_t data_size)`

addr - The address at which the data is read.
data - The buffer onto which the data read is stored.
data_size - The size of buf.

Communicate to the chip over SPI and read multiple bytes at chosen address onto onto a buffer.

`void ice_flash_erase_sector(uint32_t addr)`

addr - The beginning of the sector

Erase a sector of the flash chip at the given address.

`void ice_flash_program_page(uint32_t addr, uint8_t const data[ICE_FLASH_PAGE_SIZE])`

addr - The address at which the data is written.
data - The buffer holding the data to be sent to the flash chip, of size @ref ICE_FLASH_PAGE_SIZE.

Program a page of the flash chip at the given address.

`void ice_flash_erase_chip(void)`

Send a command to erase the whole chip.

`void ice_flash_wakeup(void)`

Send a command to wakeup the chip.

`void ice_flash_sleep(void)`

Send a command to put the chip to sleep.
