I'd like to know the differences between M0054-1, M0054-2, M0154-1, and M0154-2.

Hi @dongsup-seo 
It's a fair question but please provide some context for your concern.
Aside from the boot image needed (see link below), the design changes are largely transparent to the end user.

Thanks

@Vinny  Thank you. 
During the installation of voxl-suite 1.1.3 (on about 20-30 devices), some devices showed slight abnormal symptoms (such as being recognized as KONA-QRD devices), 
So I was wondering if it might be due to device revision differences. 
I would like to know what the difference is between M0054-1 and M0154-1.

@dongsup-seo , 

We will prepare a better summary of the differences between M0054-1 and M0154, but the main reason for the new board revision was to update some parts that were becoming obsolete. The differences between the two boards are very small.

When the device appears as KONA-QRD device, this means the VOXL2 was not flashed completely, I think @tom should be able to answer the questions related to that.

@dongsup-seo I would recommend flashing the latest SDK (1.4.1) as that will  have much better handling for M0054-1/2, I think a lot of that logic was missing on 1.1.3 as that is very old.
