Since I have not NUC6CAYS, can you send me the following info in NUC6CAYS:
1. Power on, press F10 to enter the BIOS boot menu.
2. Select boot to UEFI shell.
If there is no UEFI shell, then you need enter BIOS setup program to disable the
secure boot and enable the boot of UEFI shell.
3. After enter the UEFI shell, there is a list of the supported block devices.
4. You can use Page Up and Page Down key to check the whole list.
5. Take a picture of the BIOS version and block device list and email it to me.

Currently kernelflinger in Celadon support the following storage type:
eMMC, UFS, SD card, SATA, NVMe, and also support USB if enabled (disabled by
For eMMC, we already verify that kernelflinger in Celadon support eMMC in Joule, KBL
RVP, Leaf Hill.
Kernelflinger check the eMMC device use two methods:
2. Device path sub type is MSG_EMMC_DP.
If the BIOS does not support anyone of the above methods, then kernelflinger can't
support eMMC in this device.
If you verity that the kernelflinger can't be running in eMMC in the NUC6CAYS and
you own N3350 APL device, can you check the BIOS whether support the above method? Or we
need to buy a NUC6CAYS to verify it, or we modify the kernelflinger to add more log, and
mail it to you, and let you help us to debug it.

Until now eMMC boot & storage wasn't scoped for APL Celadon, you can make a formal

We'll try validating this on APL-NUC and get back to you if there is any progress.

eMMC is not supported in celadon as of now.
Means that there is no support in kernel flinger, however the kernel drivers are in place,
though it is not validated for eMMC boot or external storage.
Thank you and Regards,

I've been testing Celadon on two platforms, both with eMMC (NUC6CAYS and a Celeron
N3350 APL device). For the NUC6CAYS I've disabled the eMMC and used an SATA SSD. Our
final product plans, however, require use of eMMC storage. Kernelflinger appears to not
support the flavor of eMMC being used by these two devices. When using a GRUB installer
image, I'm able to lay it down, but the unit fails to boot and eventually shuts off.
Is there any guidance around usage of eMMC storage with Celadon?
