KiwiSDR unintentionally shutting down (caused by SW update???)
I have two KiwiSDRs, one local, and one in a remote location 200km away. The remote Kiwi has had a bad habit of turning off without any explainable reason. Since I only visit the remote site in weekends, I switched the two Kiwis previous week, so now the suspect Kiwi is in my primary location.
Last Friday I drove up to the secondary site, bringing the "good" Kiwi. I connected it to antenna, ethernet and power, and switched it on. When trying to log in, i got the response "software upgrade in progress...". (v1.424)
When trying to log in to the other Kiwi, at the primary site, it was dead. No ping. (it was working a few hours earlier)
Both Kiwis have similar power supplies (lab power of 3 or more amps (at around 10V) followed by a LM350T 3A linear regulator at 5.5V inside the Kiwi aluminium profile cabinet (not the original one), current consumption ca 0.6-0.8A fluctuating
I have measured voltages on the Kiwi when it is in the error state:
:input at the Kiwi barrel connector 5.5V
:5VExt pins to BB 5.5V
: 5V from BB ~0V
:3.3V from BB ~0V
The shutdown has been occurring regularly, at least since June/July, and for a while, I am getting a strong suspicion that is is coincident with the software update process. It seems _this_ Kiwi runs a SHUTDOWN and not a reboot after update.
I have not yet restarted the "dead" Kiwi, awaiting tips/advice on checking logs and startup messages from the Kiwi,
