The process is completely automated and is based on converting the
header files that come in the CMSIS packages of the processors.
I will send you the file for that chip via pm, you will also have to
tweak compiler/systems/t_embed.pas compiler/arm/cpuinfo.pas but this is
pretty straightforward, only extend both structs for the processors.
There is a second class of Headerfiles that were done half automated
(afaik) by Jeppe Johansen that covers the STM32F7 series. Those Headers
more closely match the STM32 code C-code examples but are a lot less
portable to other chips (Microchip etc...)

Hello list,
I'd like some pointers on generating the RTL files for a processor I
am interested in, the STM32L432KC (which is available for ~$15 with
JTAG on a "Nucleo" board from STMicroelectronics).
The CMSIS (Cortex Microcontroller Software Interface Standard) files,
as they come from STM, use structures to represent the registers. The
example RTL files for STM devices seem to follow this pattern fairly
well, but I would like to know about any discrepancies; I opened one
file and think it was structured more closely to the way libopencm3
does things, but I can't find it again. This may have been the file
for the NXP part listed on the Wiki.
How much was converted by hand, and how much can be automated? M4
devices are noticeably more complicated, and even though this is a
hobby project I am worried about the time investment required to get
my device working with FPC.
What complicates things is the way libopencm3 has their headers
structures is more standard. They avoid using structures that
represent the registers, instead using faux namespacing with lots of
underscores in macro names.
Cheers,
R0b0t1
