[BH] Issues booting from eMMC with NON-BOOTABLE SD card inserted
#1
Hey all,
    I've scanned the forums and haven't seen this mentioned before, but apologies in advance if it has.
    I've flashed a distro to my eMMC flash and it's working great with one exception. Cold booting with a non-bootable (no OS installed) flash drive doesn't seem to work.
     In the past, booting from an SD card, I would insert the SD card, re-insert the battery and press+hold the power button for several seconds and I see the usual boot sequence starting; within a few seconds the status LED would cycle through it's colors and then I'd see a brief flash from the bootloader on commandline before my OS of choice's boot logo, etc...
     Now that I've installed to eMMC, when I power up with a non-bootable SD card inserted, none of the above occurs, not even the status LED cycle, which leads me to believe this is a hardware/firmware issue more than OS/software.
     From what I've read in the wiki, the firmware is set to scan the SD card before attempting to boot from onboard memory.  I've checked the drives I'm using and they are not flagged as bootable in gparted, so I'm wondering if the firmware isn't checking for a boot flag, but just the mere presence of an SD card?

     This isn't a terribly urgent issue for me, but I was wondering if others have experienced this as well. Perhaps it's only on the Braveheart edition? If so, does anyone know when PCB 1.2 will be available in the Pinephone store?
     Thanks in advance!
