Reference design for adrv9364-z720 + adrv1crr-bob and adrv9364-z720 + adrv1crr-fmc

Hello,

Currently I have the ADRV9364-Z7020 + ADRV1CRR-BOB boards, as I don't have the possibility to add an external oscillator,
they told me that I should buy the FMC board for the ADRV9364-Z7020. As my idea is to customize the HDL reference, I followed the suggested steps in Analog Devices to have the HDL reference. Regarding this I have two questions: 1) When I upload the image to my board, the latest version is not compatible with the BOB, so I opted to use version 2019_r1.
In this case I should use the hdl_2019_r1 reference, but cloning from git I get the latest version. How do I get a different version? 2) Cloning the hdl reference, I find that inside / projects / adrv9364z7020 I don't have the fmc board.
Does this mean that I will not be able to customize a design using ADRV9364-Z7020 + ADRV1CRR-FMC? Thanks, Nicole.
