ZP100 not booting

Hi,

I've recently acquired a ZP100 however it looks to be stuck in the boot process with a single white light flashing endlessly.

It doesn't appear responsive to holding the mute button on bootup. On powerup all of the network port light flash briefly and the connection lights are solid if wired to bridge via ethernet.

I know this is an old product and I know it is my fault for purchasing it, but is there any other reset tricks or way to update the firmware to get out of this loop?

    Hello

    I got to connect my raspberry pi UART (i dont have a bus pirate) to the ZP100. Im now connected and with ZP100 shell operational.

    Can you please elaborate a little bit more the procedure of killing anacapad? i have tried the following commands but im still seeing several anacapad processes when i run "top"

    code:
    touch /var/run/stopanacapa
    killall -9 anacapad


    code:

    Also, i have already downloaded the current firmware to my pc and im getting the HTTP server ready. i have a question regarding what route should i put the file on so the ZP100 can find it? what ip address should i assign to my pc and what link shoul i emulate?

    Would really appreciate your help! i believe im getting closer to revive that thing!

    Hello all.

    I want to report excelent results reviving my unit. Here is my procedure.

    Since i dont have a bus pirate i had to use the uart that comes in my raspberry pi. connections are pretty much the same.

    i used a program called screen in order to connect to the uart:

    code:
    screen /dev/ttyAMA0 38400


    i created the http server with abyss web server on windows and hardwired the unit with my pc. pc had a ip address of 169.254.1.2 and firewall off just in case.

    emulated the download route like this:
    code:
    http://169.254.1.2/firmware/Gold/28.1-83251-v5.2-pcyakr-RC4/28.1-83040-1-1.upd


    make sure zp100 can ping the computer.

    killed anacapad. had to do it several times until it showed no more processes.

    code:
    touch /var/run/stopanacapa
    killall -9 anacapad


    ran some magic
    code:
    cd /bin
    upgrade http://169.254.1.2/firmware/Gold/28.1-83251-v5.2-pcyakr-RC4/28.1-83040-1-1.upd?cmaj=27&cmin=2&cbld=80271&subm=3&rev=2®=1&serial=000E5XXXXXXX&sonosid=112XXXXXX&householdid=XXXXXXXXXXXXXXXXXX


    first time, it got stuck somewhere on the way and upgrade didnt go through. i power cycled and did same procedure. here is the output.

    after this, unit rebooted and got dhcp address from my router after reconnecting, it updated to my lastest running version which is 29387150MainlineAlpha.

    just an advice that worked for me. run a hard reset after this on your zp100.

    i will do more testing since i note that the unit behaves weird on the alpha version that im running.

    thanks to all the people who has posted here. all these have help me a lot!

    Hello.
    More details about my system. Unit has been very weird lately. It associates sometimes to my system and it keeps freezing after a couple songs. It's still pingable and it has a valid ip address but sonos controller just can't find it. Also, http is not accessible.
    I tried to connect again to the shell via uart but cannot get any command prompt.
    I also tried to reset it. I press mute and volume up, flashes white and then flashing orange appears but won't turn to green. It will stay blinking white/orange.
    sometimes after rebooting, green led will flash but wont associate agan to sonos system.
    I'm running out of ideas here. 😞

    Hi @andresmorago, is this the same unit that you revived recently? If so, have you tried running it with a version of the firmware that is not the alpha?

    Yes. Same unit. The thing Is that I can no longer access either uart or regular operation of the unit. It's very unresponsive.

    So, the fact that you cannot access UART is not super suprising, since the production firmware doesn't have serial access. If you are connected to the machine while booting, does the bootloader info show up?

    andresmorago,

    Always prove that the power supply is stable before getting excited about anything else.

    hello again.
    unit works once in a while and wont stay stable for more than a couple minutes.
    i managed to downgrade it to a stable version (5.3) but still not fully responsive.
    i improved my uart connections and this is what i got when i first power it on:

    code:
    Rincon boot loader version 1.0-27270(ZP) (32M SDRAM). Press 'h' for help.
    SDRAM test...
    Memory test iteration 0
    SDRAM test complete
    Attempting to autoboot from NAND device
    NAND ID is 20:75
    32M NAND flash (ST NAND256W3A) detected
    NAND flash block 1710 is bad
    Section 0 is provisionally good, kernel on partition 1, generation 7
    Section 1 is provisionally good, kernel on partition 4, generation 6
    Attempting to boot kernel from partition 1


    NAND seems to be the problem.
    is there anything else i could do?

    Given the age of the units, it's not that unusual to have a couple of bad blocks. I very much doubt that is an issue. This sounds more like a power supply issue to me.
