Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual sh...

Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...

Hello,Can anyone provide a bit of clarity regarding ST's "Marketing Status" terminology? For example, in the STM32CubeMX MCU/MPU selector, I see the following entries for various 'H7 devices:"NA", "Proposal", "Evaluation", "Preview" & "Active". I p...

Hello,I'm hoping to get clarification on the dual-bank flash availability in STM32G47x parts with fewer than 512K of FLASH. The datasheets (DS12288 & DS12712) cover the B, C and E flash sizes. The first page refers to "up to 512KB Flash", yet there...

Long ago promised; twice deferred. Please update your community on this release! Thank you!Regards,Dave

Now that ST is promoting the STM32MP13 as a real-time solution, it would be a logical addition to the Azure licensing list?

Hello Martin,Are you unlocking and writing the option bytes somewhere? After that, they take effect at the next reset or immediately if you "launch" them.Regards,Dave

The CORDIC operations are faster than a sequence of instructions, but of limited precision. You can also overlap a few instructions while the unit is busy.

Hello GRodr.7,Was Boot0 floating? Notably, you are noticing an effect from the adjacent pin, so my guess is that it was floating...Regards,Dave

Hello Tom,Perhaps try "asm("ldr R0,=0x8001005"); //my app start address"I believe Thumb-2 addresses are designated by bit-0 set.Good Luck,Dave

Re: I am interested in STM32U5 because of CORDIC as I do have trigonometrically intense applications. Apparently DSP with hardware multiply is superior, and is also provided in the STM32U5. Respectfully, why include CORDIC when DSP is also available?
