Hi everyone,
In my opinion, use the picozed without a carrier board it doesn't make sense. You always are going to need a carrier board. Avnet has two models the PicoZed FMC Carrier V2 and the PicoZed FMC Carrier V1. And the company I'm working, it is going to desing a custom carrier board according to our necessity.
So maybe, it's better to have only two .dts files. zynq-picozed-fmc-v2.dts and zynq-picozed-fmc-v1.dts.
If we decide to have the zynq-picozed.dtsi and zynq-picozed-fmc-v2.dts, we'll have to decide what hardware description is going to be in the zynq-picozed-fmc-v2.dts and what hardware description is going to be in zynq-picozed.dtsi.
for example the spi0 hw is in the picozed board, but the SD (mmc0), eth0 (gem0) and serial0 (uart1) the HW is in the picoZed but the connectors are in the PicoZed FMC Carrier V2, so It's a little bit confused if this HW description has to be on the zynq-picozed.dtsi file or in the zynq-picozed-fmc-v2.dts file. Do you know what I mean?
Please let me see you opinions about that.
I understand your concern. These SOMs are problematic and it is up2you how you want to do it. My preference would be to add common stuff to dtsi file and carried board stuff to dts file. If that configurations have nothing in common then using just fmc dts is fine for me. When ps7_init.* files are in place it should be visible how MIOs are configured.
Thanks, Michal
