Function Documentation

int tffs_boot_partition (  int  drv, unsigned int  rtosSize, unsigned int  sbcSize0, unsigned int  sbcSize1 )

First, this function erases (set to all 1's) the EEPROM erase units that will be reserved for the boot partition. This is caculated using the total of the size parameters. The total size must end up aligning to a 64KB boundary. Next, a bank header is written to the head of the boot partition. The bank header size and offset members are determined by the size parameters passed to the function. A checksum is calculated and stored as the first word of the bank header. In addition, 256 bytes of EEPROM in the boot partition is reserved for an NVRAM emulation area. Parameters: drv  The TFFS drive number (0 or 1). rtosSize  The size in bytes to reserve for the RTOS file in the boot partition. sbcSize0  The size in bytes to reserve for the SBC file 0 in the boot partition. sbcSize1  The size in bytes to reserve for the RTOS file in the boot partition. Return values: 0  Success. -1  Failure.
