    I have been running my ESPRESSOBin in production since the day after I got it, with no heatsink and without issue. That said, I haven’t run any super intense workloads on it, as it is being used for NAS mostly, not computation and I compiled my kernel on a different system.

    Also, just to be fair here, I do have it mounted in a case where there is plenty of airflow so this may also be why I haven’t seen the overheating issue.

    TL:DR:
    I haven’t seen any overheating issues yet with my boards and I am not using any heat sink or fan. Haven’t tested under extreme workloads, but at the same time I do have it in a place where it is receiving passive cooling by fan.

    Good luck to you guys figuring out something that works for you!

    Cheers!

    Sounds to me (just guessing here) like you hosed u-boot on the SPI NOR chip. You should be able to place u-boot on an sd-card and boot from it. Once in u-boot on the SDcard you should also be able to re-load u-boot on the SPI NOR (assuming this is the issue). I am not sure if they have this process documented yet, but at least writing u-boot to an SDcard should allow you to boot into an operating system.

    Hope this helps!

    Cheers!

    You should consider getting one of the following:

    This will adapt the Molex to SATA power that can be plugged into SATA your drive for power.

    Hope this helps!

    You may wish to see this thread for how to boot from SATA: Armbian Forum

    Also including some info below:

    setenv bootcmd 'scsi scan; scsi dev 0; ext4load scsi 0:1 $kernel_addr $image_name;ext4load scsi 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/sdb1 rw rootwait; booti $kernel_addr - $fdt_addr'
    save
    run bootcmd

    In the post I include my u-boot config for booting from SATA. If it will be the only drive attached and you do NOT have USB drives connected it should be changed to reflect /dev/sda1 in your case.

    I also used Boot from removable storage – Ubuntu as a reference, and if you type help while in u-boot its pretty easy to get help on the needed commands.

    Hope this helps!

    Cheers!
