Hi all, I'm experiencing a strange issue where every once in a while I am unable to enter bootloader on the STM32G0. I have the option bits set correctly and have a hardware push button connected to both nRst and Boot0. I can normally hold the Boot0 ...

I'm working through some code size optimization efforts and noticed that our list file includes some calls to __assert_func. We're not using asserts in our codebase so I'm guessing one of the standard libs is using it. I checked and we have defined N...

I'm building an application for an STM32G0 and noticed that quite a bit of double precision libs such as _strtod_l, __aeabi_dsub, __aeabi_dadd, etc are shown in the linker file. As far as I know, there is no double math being done but obviously somet...

I'm trying to setup a CAN-FD example with data rate switching (1MHz nom, 8MHz data) on an STM32G0B1. It seems to work up to 4MHz, but when I decrease my divisor to get to 8MHz, the CAN frames just stop after the arbitration. Here's my init code that...

Out of no where, seemingly from one build to the next, CubeIDE is not able to launch GDB. I've tried a different project, a different version of the IDE, restarting my PC and no luck.How do I debug what is going on?STMicroelectronics ST-LINK GDB serv...

We have this working with a G0. What are the issues you're facing?

Can you expand on when we need to "remap by hand before making the jump, so SYSCFG->MEMRMP = 0x01" and why this is needed?

I'm not trying to change the bytes though. I set them once and then keep them the same. All I'm doing is powering up and the powering down the ST-Link on board the Nucleo. Is there anything else that latches?

Okay, I did some more digging and this is reproducible on a NUCLEO-G071RB. See steps belowConfigure option bytes using STM32 Cube Programmer:nBOOT_SEL = UncheckednBOOT1 = CheckednBOOT0 = CheckedReproduce expected behavior:Flash blinky app to Nucleo t...
