Test NameStatusNotesModified
Board Status 0 Found and fixed a short on U40 pin 14-15, still see an infinite number of chips on prom chain. U40 possible gone bad. -AC 4/30/08 Saw an infinite number of chips seen in prom chain when initialized in impact. This fault seen for J6 and J7, J4 and J5 show no fault (alex 08/09/08). Tested input/output and clock trace between U28, V2 PROM, V4 PROM, and Misc. PROM with multimeter. Also tested TMS trace between the 3 PROMs. All traces are good (i.e. read as 0 ohm resistance). Found possible fault for the V2 PROM where it received TDI signal but did not output a TDO signal. (Philip 08/09/08). V4_conf_PROG and V2_conf_PROG, CF* on prom chips, pull to GND. U95 replaced no improvement. Both V2 and V4 prom chips replaced by UBC electronics shop, V2_conf_PROG now correct while V4_conf_PROG still held low. V4 prom chip removed by UBC electronics shop. Loaded connectivity firmware directly to chips and the board shows no connectivity faults. (28/10/08 alex). April 2015: Components replaced (C388). 29-04-2015
