There are many reasons we moved away from the FSBL flow. The *main* reason is
that we encountered various bugs (the FSBL worked okay on the evaluation
board, but once we made our own module with different pinouts and support
chips, the bugs started to appear). With the FSBL being non-free software
("free" as in "freedom", not "free beer") we could not fix these issues ourselves.
A big issue with non-free software is that in say five years a customer will
return to us and ask "hey, can you do this small addition". Chances are that
the tools we used will no longer run on the machines we have then, and in many
cases, it will be impossible to revive the licenses. And we will have no way
of fixing that, other that putting our current machines in the fridge along
with the software.

Hi Mike,

The "open source" way is to avoid the FSBL (and in fact, all of
meta-xilinx-tools) and use u-boot SPL instead. All functionality provided by
the fsbl/bootgen flow is provided by u-boot SPL already.
"All functionality" would be a blanket statement, there are many driver
support that is officially tested by Xilinx in fsbl/bootgen flow, including
safety and security support
Thanks,

Hi, I’m aware of the meta-xilinx-tools layer, but this needs you to have
the Xilinx SDK installed (unless I’m mistaken), I was wondering ion there
were any plans to create support in meta-xilinx for building the FSBL
without the need for the SDK dependency. Peter

Hi (resending from right address),
You can indeed build the FSBL + boot.bin using the meta-xilinx-tools
layer: https://github.com/Xilinx/meta-xilinx-tools

A question, I was wondering why there is no support for building FSBL in
a similar way to that provided by meta-xilinx for the PMU firmware, is
there a technical reason or is it just one of those things that has not
yet been got around to? Thanks in advance Peter.
