The STM32U5 has HS PHY and it's slower than the STM32H5 so why doesn't the H5 have HS PHY or any HS USB support? Will a version that does be released in future? Its almost the perfect chip to use for a future project I have in mind aside from the lac...

Dear ST,I want to be able to use the clang/llvm toolchain here: https://github.com/ARM-software/LLVM-embedded-toolchain-for-Arm/tags with STM32CubeIDE.There was a comment on this community site that you would be looking in to custom toolchain support...

Hi there ST!Could you please merge my PR: https://github.com/STMicroelectronics/STM32CubeG4/pull/39I noticed whilst working on some extremely high performance code using M4 intrinsics that rotates between AOS and SOA for computation using the __PKHBT...

I have the following function to sum 32 16bit signed integers as optimally as I think is possible:int16_t sum32elements2(int16_t vals[]) { uint32_t s1 = __SADD16(*(uint32_t*)&vals[0], *(uint32_t*)&vals[2]); uint32_t s2 = __SADD16(*(uint32_t*)&val...

I'm pretty amazed that you haven't merged this and closed it because your extremely old copy of CMSIS has this old header setup for __PKHBT and __PKHTB and you don't seem to be interested in having an even vaguely up to date CMSIS build. Could you PL...

Hi @Pavel A. thanks for the reply. No, I've not seen any toolchain manager for CubeIDE unless you are referring to this:Which doesn't support anything other than gcc due to the way the interface is designed to require a specific directory structure t...

It is now half way through 2023 and I see no evidence of support for custom 3rd party toolchains for STM32CubeIDE. Am I missing something? Why wasn't this support added? Why do we still, for instance, not have the ability to use llvm/clang? Thanks.

Thanks. If I crack around 41 cycles I'll post full details about my insane journey. It's been a blast. Super great responses from people here have been very helpful.

Thanks, all great points, that really helps. I will do those things shortly.
