in UP Squared Troubleshooting and FAQs

MPN: AAEON: UPS-APLP4-A10-08128
Part description: SINGLE BOARD COMPUTER UP^2 (128GB)
Part S/N: C18623921
Failure symptom: cannot find the hard disk frequently

we installed UEFI and eMMC showed up at boot menu in BIOS in the beginning.
But when we re-boot, it doesn’t show. Then when we enter BIOS, we cannot find the previous UEFI bootmgr.
eMMC shows up occasionally but not always.

    Hello @DCleri
    • Which power supply are you using?---------------------------------------------------normal PC POWER 5V DC SUPPLY
    What operating system have you installed on UP Squared?---------------------Window 10
    Have you tried to reinstall the system already?-------------------------------------reinstall the system more than 10 times
    • Currently, the main issue is that it may be missed the hard disk memory units when setup the board discontinuously .
    • Especially when tighten the four screws from board to heatsink, The board’s disk memory units always be missed.
    • Probably we doubt the board’s disk memory units IC has soldering issue.

    @DCleri we don't think this is some kind of application problem becasue it is not the first time we used this part. Our PE thought this was a quatliy issue caused by the soldering problem. please advise your comment asap. This part is urgent for our production. thanks.

    Hi @ASM2019

    After the information you provided, the problem seems most likely an hardware issue of the specific unit.

    Please apply for RMA request from the shop you bought your card and leave a reference to this topic for their information.

    Hi,
    I have the same problem. Until now I had 6 UP Squared, which all worked fine. But with this UP Squared, I was able to install Windows10, but after a time it did not recognize the eMMC.
    I will do as you suggested.

    Hi @Luc_sisseln

    Is also your board a UPS-APLP4-A10-08128 ?

    Please help to confirm if that is the case.

    If the above steps do not work, please apply for RMA through the shop.

    Hi @DCleri
    Yes, I confirm its the A10-08128. The other 6 Up-Boards we are using are also the same, but all work fine.

    Is this issue (e.g. other eMMC) solved with the newer version? And how could I find out if I have a newer version?

    Please apply for RMA for the board that doesn't work.

    It can happen that a board eMMC doesn't work as expected, but the failure rate that we experience is still very low and it shows usually at the beginning.

    I was asking just to understand if it is the same case and report back to our hardware team.
