Function Documentation

int fpga_inputEnable

(

void

)

enable the inputs from only if the bits 0-7 are output and 8-15 are inputs.

returns if sucessful or terminates.

Test if 0-7 bits are outputs

reinitialize

int fpga_loader

(

crc

load_crc

)

Loads the fpga specified by the crc.

Parameters:

load_crc

The crc of the fpga to be loaded. returns: 0 on sucess or error code.

Initializa the CRC engine.

Find the address which matches the CRC. If there is not match while returns with null

Copy the FPGA from FLASH to RAM

Compute the CRC of the FPGA

Check if the memory has the required CRC

Continue with the other address

Load the fpga
