STM32U5 support
Hello everybody,
I have started to work on STM32U5 support for Apache NuttX and would like
to get some feedback on how this should be integrated. Realizing that
support STM32F0, STM32L0 and STM32G0 is all handled within
/arch/arm/src/stm32l0g0f0, I would like to rename /arch/arch/src/stm32l5 to
/arch/arm/src/stm32l5u5 and change filenames and literals accordingly.
Would you please let me know whether corresponding changes will be
acceptable?
Thanks!
Michael

This should be good!

Got success to run o LOM204 the Nuttx
Uses the STM32L0

Hi David, Hi Miguel,
thanks for your feedback!

To me the U5 seems to essentially be a re-spin of the L5 on a new
technology node. However, the IP blocks have been updated considerably. I
assume such subtle differences in the IP blocks have been the reason for
the breakage problems you mentioned? I agree with you and will start a new
stm32u5 arch.
Thanks again
Michael

my plans to 2022 is to test on STM32L071, because we sell STM32+SX1276 modules and i want to test the LoRa!

Hi Michael,
Of course you are much closer to the problem than I am. So here is just my
opinion based on the stm32, stm32f7, stm32h7 lessons.
Are the L5 and U5 the same with different marketing names or are there
underlying IP differences? What is the delta?
I would head the direction of splitting them up unless there are only minor
pin map differences and then do those as wrapped includes (see the
stm32F412).
The decoupling adds maintenance overhead but prevents the breakage that we
endured in the stm32.
