Re: [Discuss-gnuradio] Dead USRP box?

[Bob Cameron]

Hi Berndt

Have you heard this happening on more than just our boards? Weird!

I assume you have the same blinking LED so this excludes the EEPROM load from the problem? I use to work on some Alcatel data radios with the Altera chips and we had EEPROM failures every now and then.

I have emailed Matt in case he offers a repair service. If not I might just wait till you have repaired yours. <grin>

Cheers Bob

G'day Bob,

this is exactly what happened to my USRP board. The board seems operational 
except it won't communicate. I've ordered the FX2 chip from DigiKey as I 
believe it to be faulty. Digikey actually managed to sent me the wrong part, 
a RAM chip, inside an otherwise correctly labled package. The hopefully 
correct part is on its way, so it shouldn't be long until we know if it fixed 
the problem.

It just begs the question, what causes this chip to fail? As described by Bob, 
it was left off for several month and failed on subsequent power up.

Seasons Greetings,

cheerio Berndt
