Function Documentation

int blackfin_setup

(

void

)

blackfin_setup Initialize the blacfin processor.

This function:- 1. Sets up the CCLK = 600 MHz (default); SCLK = 100 MHz (default) 2. Configures the uart to the default baud rate 57600 bps, 8 bits, 1 stop bit 3. Sets up the PORTF in accordance with TLL6527M_FPGAv1-3 configuration

Pre-conditions:

• None.

Post condtions:

• Blackfin ready for fpga programming

Parameters:

Returns:

Zero if the uart is initialized properly. Negative value if the init fails.

int fpga_outputToPortFEnable

(

unsigned short

mask

)

Enable the output FPGA toward the CPU.

The mask is currently unused and may be used in the future

Set cam high for CPLD

int fpga_setup

(

void

)

fpga_setup

This function programs the FPGA.

Pre-conditions:

• The FPGA program data (*.bin file) and should be stored in SDRAM at address pointed to by "FPGA_DATA_START_ADDR".
• The TLL6527M specific 3:8 decoder mapping should be initialised

Post condtions:

• Transfers the data and confirms FPGA programming by by probing FPGA_DONE pin

Returns:

Zero if the FPGA programming was successful. Else negative value.

int fpga_setupById

(

crc

fpga_crc

)

fpga_setupById

Parameters:

load_crc

the crc of the fpga to be loaded return status code.

void RTC_init

(

void

)

RTC_init.

Initializes the RTC to work without the prescaler in order to set the RTC counting frequency to 32.768KHz

void RTC_waitForInit

(

)

The RTC is initialized by default, but needs ~1 second for changes to the prescaler (on by default) to kick in.

This function should be called if the RTC is to be used as soon as a program starts.
