Hi all,
another sick Boom just arrived. Besides a mostly burnt display, it also
needed a new power supply connector. But that's not all. It can't
connect.
Here is the list of symptoms I could find out so far:
- Logitech logo does not appear on startup. Instead, the display stays
dark longer than usual and the first thing I can see is "obtaining IP
address"
- the Ethernet (wired) MAC in my DHCP server registers as
04:00:04:00:04:00 which clearly isn't right. But it gets an IP anyway.
A device name is not shown in the DHCP server at all
- in the Boom's setup menu (after pushing the "back" button for some
seconds):
- I can see both my Logitech Media Servers, however it is not
possible to register with them, and the server logs do not show any
contact
- DNS server and Squeezebox Server are indicated to have IP address
4.0.4.0 which is nonsense of course
- sometimes, the device's own IP address also reads 4.0.4.0
- sometimes, the MAC address is shown as 00:00:00:00:00:00
- sometimes, going to the settings requests a setup lock code which
is 1024 (found that out while I could go into the settings without
the code). Most of the times however, I can get into settings
without the code
- I have changed the MAC address manually to what is printed on the
bottom label of the Boom but this setting is immediately lost again
- setting the MAC is somehow restricted where it shouldn't be. The
second digit of the first MAC segment can only be set to 0 or 1 when
using the "up" button on the IR remote. Using "down" reveals the
values 9, 8, 1, and 0. All other segments work as they should
- the factory reset available in the settings did not help
- in some submenus, random horizontal lines appear on the display's
right half
- the display shows two lines where the pixels are considerably darker
than in the other lines. They do show the right content. The display
is brand-new, the old one showed the same issue. This must be
something the Xilinx processor is doing wrong in controlling the
display
- _Xilinx_and_factory_reset_both_cannot_be_triggered_on_startup_,
neither from the IR remote nor the main user panel. It seems the
firmware jumps right past the phase where these keys would be
evaluated (remember the Logo does not appear either)
- running the PCB without the Wi-Fi card, or using a new Wi-Fi card,
did not fix it either
- if the Wi-Fi board is not inserted, the PCB ends up flashing
"Wireless ca" in huge letters and kind of shifted (see attachment),
probably that's the same text as the "Wireless card not installed!"
message that pops up every seconds in the first display line in the
menu
This reminds me closely of the "MAC not set" issue I had (see
'https://forums.slimdevices.com/showthread.php?104987-MAC-not-set)
' (https://forums.slimdevices.com/showthread.php?104987-MAC-not-set)The
impression is that whatever causes the behavior is becoming worse over
time. Settings are incorrect right from the start, but at least the IP
address received from DHCP is valid at first. It gets lost after a bit
of time though.
What happens in the MAC setting screen indicates that some data line is
corrupted and at least one bit is lost. The PCB does not have visible
damage of any kind. From the "MAC not set" drama I remember that
desoldering the flash EEPROM and creating a dump of it is likely to
prove that the firmware image is actually okay, the issues appear to be
more in the region of the CPU or the RAM, however, changing the RAM chip
for a new one did not help last time.
Also tried gently flexing the board, pushing the CPU, applied freeze
spray, all to no avail.
If only I could trigger the Xilinx reset!
Looks like another death, dammit.:(
