==Testbed's hardware Hardware and software configurationSoftware Configuration==
As stated before, the procedure was tested on Bora/BoraEVB hardware platform.
*U-Boot 2018.1 (at the time of this writing, this version was not officially supported by any BELK release yet)
*Linux kernel 4.14.0 (at the time of this writing, this version was not officially supported by any BELK release yet)
*Root file systemfilesystem: extracted from [http://files.digilent.com/Products/PYNQ/pynq_z1_v2.3.zip Pynq-Z1 v2.3 image] and mounted from microSD card.
Original root file system included several kernel drivers built as modules. The Linux kernel used for this test was different than the kernel released along with the PYNQ's root file system, however. Consequently, these modules were not compatible with the kernel running on Bora. To overcome this issue, these drivers were linked statically into the kernel image.
==Setting up Up the boardBoard==
U-Boot environment was configured in order to retrieve the kernel image and the device tree blob from the microSD card. Also, it was configured to make the kernel to mount the root file system from a partition of the microSD card.
The following box shows the full boot process (clock on the "Expand" box):
