Function Documentation

edt_get_board_description()

int edt_get_board_description	(	EdtDev	edt_p,
		int	force_mezzanine
	)

Get board description.

This attempts to learn as much as possible about the board referred to by edt_p. If the bitfile that's loaded has an option string defined, fill it in and parse its fields if possible. If edt_p is not channel 0, channel 0 is opened, examined, and its fields copied to edt_p. The bfd structure within the EdtDev structure is filled in as much as possible.

Parameters

edt_p	The open EDT device handle.
force_mezzanine	Attempt to load a bitfile to characterize the mezzanine board if no bitfile is loaded.

Returns

0 on success, -1 on failure

void edt_print_board_description

(

EdtDev

edt_p

)

Check the current bitfile to see if it's a test file.

Parameters

The open EDT device handle.

Returns

1 if test file, 0 otherwise

edt_read_option_string()

int edt_read_option_string

(

EdtDev

edt_p

)

Read a new-type option string from the FPGA and copy it into the EDT device handle's internal bitfile descriptor.

EdtBitfileDescriptor.optionstr and EdtBitfileDescriptor.revision_register members.

Parameters

edt_p

The open EDT device handle.

Parameters

bfd	Bitfile descriptor to populate.

Returns

0 on success, -1 on failure

edt_bitfile_option_string()

const char * edt_bitfile_option_string

(

EdtDev

edt_p

)

Get the last EdtBitfileDescriptor.optionstr read from device.

Precondition

Call edt_read_option_string() first, to read the option string from the FPGA.

Parameters

edt_p

The open EDT device handle.

Returns

Bitfile option string.

Parameters

edt_p

The open EDT device handle.

Returns

Bitfile revision string.
