Booting Error

Jim_KangJim_Kang New Member Posts: 5

Back ground :
UP Board was located in inside of instrument. Thus we can’t push power button.
So, we change BIOS setting to boot automatically when 5V power applied.
But randomly UP board didn’t boot even if power was applied.
So, we have to disassemble an instrument and push power button for booting.

Trouble :
1)FAN & LED is normally workable but booting doesn’t proceed (NO BIOS logo) when input power.
2)If we push power button when 1), booting proceed normally.
3)After 2), there was no booting error anymore.

Test Condition:
1)BIOS Version : UPC1BMOT / UPC1BMOS / UPC1DM17
2)BIOS setting : Default (State After G3 [S0 State])
3)Test method : 5V Power ON/OFF in a cycle and then monitor booting process (25sec On / 2sec Off)

This is critical problem for the instrument manufacturer....

    @Jim_Kang
    Do you mean the UP doesn't start, booting when 5V power applied? And easy to reproduce the issue with power on/off test (25sec On / 2sec Off)?
    Please provide us with the following information
    1. Steps to reproduce this issue, or Video
    2. UP board serial number

    Same issue here (UP 4Gb/32Gb, Ubilinux Kernel, Ubuntu 16.04, No graphical interface, No monitor, No keyboard). It is not easy to reproduce the error since it happens randomly every 100 boots (more or less). We guess it should be something related to the voltage profile during the power loss. When this happens you may cycle power as many times as you wish but until you do not push the power button again the UP does not come up.
    Once booted manually everything is normal, bios configuration are correct (State After G3 [S0 State]).

    Since we have several of these devices (actually about 100) in embedded prototypes (which cannot be opened and manually restarted all the times) we hope there could be some setting to force Autostart at every power cycle. Could it be?

    Thank you for your reply in advance

    @Carlo Alberto
    Give me a list of serial numbers, or any
    I need to check which version of UP are you currently using

    MAC Address is 0007 3242 D69D
    Firmware was updated to last available version at March 2019

    This happened so far on at least 4 different models (The others are at customer site at the moment), during an
    experimental phase of 36 prototypes booting on average 8 times daily since February 2019. It is a transportation
    related application and power is attached to the engine so it can be loss at any time and reattached at any time.
    Power was adapted from battery to 5V PS using a 50W TRACO Power DC-DC converter (in 9-48V out 5V).

    The system is fully embedded (no monitor, no disk, no keyboard) and having a readonly filesystem (overlayroot-fs)
    we have no trace in the log of what happened before the event. The only log we collected was CPU temperature
    which however was below 55°C.

    Half of the UP (60 of them from ) were bought early 2017 from Digimax, while a second half (about 50) were bought
    from different Italian resellers (RS-Components, Digimax, Mouser). In a similar application, some of them (6) reboot
    daily since April 2018 without any issue.

    If this behaviour is model related I would like to know that since we are planning a much larger exploitation and
    we need to be sure (at least) that this issue is solved and it will not happen on next and on sale models.
