if you hardwire the unit to your router, what do you get when running arp -a in any network device?

connecting ZP directly to my computer. And computer is set to static ip address of 169.254.1.2/24 default gateway of 169.254.1.1
Here's the output from arp -a

arp -a

apparently, there is no ethernet traffic at all from the unit.
what happens when you try to factory reset it?
also, when you connect it to your network, are there any dhcp requests?

On a working unit, when I hold mute button and plug in the power, the LED eventually flash in amber/orange. After release the mute button, LED eventually shows constant white.

On this problematic unit, LED continue to flash white immediate after plug in AC. event with me pressing and holding the mute button, LED never change to amber...it continue to flash white.

I'll take a look at my router log to see if DHCP request is made from the device.

nothing on router DHCP log. Consistent with no ethernet activity analysis from arp -a

I press h to get into boot loader menu

Rincon boot loader version 1.0-27270(ZP) (32M SDRAM). Press 'h' for help.
h - help

There's Boot diagnostics, but press d only result in the bad page magic.

Does anyone know what this mean? Has anyone try this option with success?

Never seen that before.
But as I can see, maybe the nand is fried? 😞

None of the production units (or indeed the diagnostic unit) that I have worked on have a diagnostic partition. A quick look at the bootloader assembly indicates that it refers to a different type of partition that I've never seen before. My guess is that it is a remnant from the development process (remember that the bootloader wasn't designed for us), that's been left in.

I have a RAM chip (ISSI IS42S16800A-7TL) ordered on ebay to replace the one that wont boot on its own. I guess I should order another one for the temperature failing one.


Did you ever get the RAM chip replace? was it easy to do?

Haven't received the chip from China yet. Replacement, well, there's certainly a technique to replacing a 54 pin SMT chip.

Would love to see some pic.
Unless you have previous experience reworking SMT boards, this is not the place to start learning. Practice on some discarded electronics first. You'll have a bunch of failed attempts until you hone your technique.

Ok. I have a zp100 and a bus pirate. I have issues getting connected. The four ports I see are on the network pcb correct? What is the pinout for them vs the bus pirate?

I get connected and see UART> that is all.

I am closer but now the system says read-only file system. That appears to be keeping me from connecting to get the firmware.

The system says read-only file system when I attempt and upgrade or wget. Also is see the Rincon boot loader but then it gets to a busybox v1.00-pre3. Don't know if that is expected. It shows to be running the diag firmware.

Got it connected and recognized now in Sonos Software. Was able to update the firmware. The device I think though is dead....as it doesn't play any audio when speakers are attached. Any idea's where to start?
Userlevel 2
could you please tell us, for reference, how did you revive it? just to keep records in the forum for future people who might need it.
regarding your other issue, check the circuit boards. do a complete cleanup and make sure the audio amplifiers arent fried.
Userlevel 2
Sure.

I used a bus pirate connected to the zp100 which was booting in diag firmware. Setup the bus pirate to run uart mode. Setup Apache on my local workstion windows 8 and downloaded the 28.1-83040-1-1.upd file. Ran update http://169.254.1.2/28.1-83040-1-1.upd. Found that you had to kill anacapa service. Once that was killed the system updated. It booted with local ip address. I had to reboot holding the mute to reset the system then Sonos software would see it. Right now I get no audio and the box appears to freeze often........the timer will begin and then the box goes unresponsive. Where are the audio amplifies on the boards?

My revived used to freeze a lot. I ended up cleaning everthing with contact cleaner and marking sure every wire was connected tight. After doing that, it came back from death and is been running for almost a month now.
Apms are located on the right side of the unit.

andresmorago: I got it working 100%. So after the unit was freezing I took it apart and completely cleaned the inside. Everything now working 100%. Doing a little burn in on the system. Hopefully it all holds. Thanks for all of the help.

What kind of cleaning are talking about hear? is just a matter of blowing compress air to rid of all the dust behind all the crevices?
