◆ edt_parse_devinfo()

int edt_parse_devinfo	(	const char *	str,
		Edt_embinfo *	ei
	)

Parse the board's embedded information string.

Parameters

	str	An embedded information string, from edt_get_esn, etc.
[out]	ei	Edt_embinfo structure into which the the parsed information will be put.

Returns: 0 on success, -1 on error (input string not valid or too long).

See also: edt_readinfo, edt_get_esn, edt_fmt_pn

During manufacturing programming, EDT embeds selected information is embedded into an unused area of the FPGA PROM. This information is preserved across reloads (via pciload, hubload, etc.) unless options to overwrite are invoked in one of those utilities. This subroutine takes as an argument the full information string, as retrieved from edt_get_esn, edt_get_osn or edt_get_sns, into the fields indicated by the Edt_embinfo structure.

(To see the information string, run pciload with no arguments.)

Note: Information embedding was implemented in Sept. 2004; boards shipped before that time will yield a string with all NULLS unless the board's FPGA has since been updated with the embedded information.

Here is the caller graph for this function:

◆ edt_get_sns()

void edt_get_sns	(	EdtDev	edt_p,

Certain information about the board, including manufacturer's part number, serial number, clock speed, Xilinx FPGA, and options, is embedded in an unused area of the Xilinx FPGA PROM at the time of manufacture.

The data is an ASCII string, with the following colon-separated fields:

serial number:part number:clock speed:options:revision:interface xilinx:

(To see the information string, run pciload with no arguments.)

Note: Information embedding was implemented in Sept. 2004; boards shipped before that time will yield a string with all NULLS unless the board's FPGA has since been updated with the embedded information.
