Embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
A kind of firmware test card of present embodiment for mainboard OBP (Open Boot PROM) being detected by CD-ROM driver interface.
Fig. 1 forms structural representation for the utility model, a kind of firmware test card as shown in the figure, it is provided with an integrated circuit modules 10, this module is provided with a CPLD 100 (CPLD, ComplexProgrammable Logic Device), this CPLD 100 is equipped with CD-ROM driver interface 140, one outside oscillator 110, a detecting unit 130 and a replacement IC120 of one 50/36 pins respectively.
Wherein, the CD-ROM driver interface 140 of one 50/36 pins can be connected to the CD-ROM drive of 50/36 pin interface, makes integrated circuit modules 10 be connected communication with the CD-ROM drive of 50/36 pin interface.
Again, detecting unit 130 is selected detection mode according to the needs of mainboard OBP, and guiding mainboard OBP carries out error-detecting.
Also have a replacement IC120, can be at any time to the action of resetting of this CPLD 100.
One firmware module 20, it is connected in this CPLD 100, and this firmware module 20 is provided with the OBP unit 200 identical with mainboard OBP, for mainboard OBP provides a comparison sample; Also have a data comparing unit 210, utilize the mode of XNOR to compare,, have any difference then to have 0 and produce when all data (DATA) homogeneous phase is all 1.
One display module 30, the electronic display 300 that it is provided with this programmable logic cells output of some demonstrations shows the mistake and the last testing result that occur in the testing process.
Fig. 2 is the structural representation of the utility model detecting unit 130, and this detecting unit 130 as shown in the figure comprises: an error-detecting assembly 132, and in mainboard OBP implementation, guiding mainboard OBP carries out error-detecting; One code write-back assembly 133 when mainboard OBP can't correct execution, is written back to mainboard with the OBP unit 200 in this firmware module 20; One selects executive module 131, selects one of above-mentioned two kinds of assemblies to carry out according to mainboard OBP needs.
The CPLD 100 (CPLD) of this test card is on the same bus (xBUS) with mainboard OBP by the CD-ROM driver interface 140 of 50/36 pin; The selection performance element of this detecting unit 130, obtain and the communicating by letter of mainboard OBP by CPLD 100, when mainboard OBP can't correct execution, select run time version write-back assembly 133, can replace OBP on the mainboard, and by carrying out through CPLD 100 the OBP unit on this card 200, simultaneously, this can be blocked OBP unit 200 and write in the mainboard, replace wrong mainboard OBP; When mainboard OBP can carry out, select error detection assembly 132, the execution signal of mainboard OBP on can monitoring bus, when OBP carries out, CPLD 100 reads in data on the bus and address (Address) information, and address information is sent to the data comparing unit 210 of this card, in OBP, obtain data by address information, this data comparing unit 210 is with the data on the bus and obtain data from OBP unit 200 and compare, wrong, the electronic display 300 that then error code is outputed on this card shows, while run time version write-back assembly 133 mis repair sign indicating numbers, not then carry out the next record data relatively, OBP is finished up to mainboard, detects by electronic display 300 outputs and passes through.
