General Description

CyMCUElfTools adds these symbols to a generated ELF file.

Their values are either defined in the linker script (GCC, IAR) or in the assembly code (ARM): (see section Linker scripts). They may be used by CyMCUElfTool as parameters for generating a .cyacd2 file. Also, use the DFU SDK APIs to refer link-time known values to the compile time.

Variable Documentation

◆ __cy_boot_metadata_addr

uint8_t __cy_boot_metadata_addr

Metadata address.

DFU uses this symbol to access metadata.

◆ __cy_boot_metadata_length

uint8_t __cy_boot_metadata_length

Metadata row size.

The DFU uses this symbol to access metadata.

◆ __cy_product_id

uint8_t __cy_product_id

Product ID.

CyMCUElfTool uses this value to place in the .cyacd2 header. The DFU uses this value to verify if an image is compatible with the device.

◆ __cy_checksum_type

uint8_t __cy_checksum_type

Checksum Algorithm of the DFU Host Command/Response Protocol packet.
