PC connected to STM32-V3SET via USB. PC COM3 sees the STLINK.STLINK is using CN7 UART TX and Rx lines to L041 USART2 configured pins PA2 & PA3. GND too.L041 has BOOT0 pin on a wire, to allow high or low level at reset.L041 has SWD-loaded program i...

I'm a newbie to STM products. Lots of experience with other vendors, and am used to seeing example solutions that go from point A to point B. STM seems to provide tool descriptions (and I understand why given the combinations of tools, versions, pr...

In Project Explorer view, I have my project directories shown as drop down lists.In >Core, my project used to show >Inc, >Src, and >Startup. Somehow >Src is no longer in the list, yet it is included in the build. I use Windows Explorer to verify tha...

Intermittent results during a loopback (same processor, Tx to Rx) test. Happens the same on both STM32L041G6 and STM32L051K8U6 processors.STM32CubeIDE (recent version) used to enable Uart2, Interrupt enabled, no DMA, 9600 baud, 8bit, 1 stop, no pari...

What about jumping to the boot loader location noted in AN2606 section 5?The ST video at https://www.youtube.com/watch?v=cvKC-4tCRgw shows a way to do this...is the L041xx system bootloader no longer supporting this method?

Thanks for your feedback but it is not helpful. My project constraints are based on our system, which was designed based on the features identified in the STM32L041 documentation and available application notes, which do not provide all the informati...

The picture in step 3 of the Option Bytes options is no longer correct (v2.10.0). There is no "Boot address Option Bytes" choice. What need to do to have the Programmer let me load code into my STM32L041xx?

The mystery continues. But I've discovered that a filter is on for the Src directory which does not show up in the Project Explorer but is built during compile/link. See graphic.But when I go to the "Path and Symbols" window then left-click on the un...

Using F5 didn't do it. I don't find any filters set up or enabled. But the git tree and debugging shows that the file is there an build with the project build.

how to get stm32-v3set with Stm32CubeProgrammer to program STM32L041?

Need to get an inaccessible STML041 into the embedded bootloader via UART, driven from an STM32L051xx. Need a documentation that describes: 1) getting from my app into bootloader mode via UART, 2) use BL to re-flash the L041 with data from L051.

STM32IDE v 1.9.0, Project Explorer View, missing subdirectory. How to get it showing again?

STM32L0x1, trying to get UART2 interrupts working. UART2 on PA2/3 is selected Tx interrupt is working, Rx is not, intermittent results. Modes: Microprocessor Communication and Asynchronous act the same. Details below.

I have been using STM32CubeIDE for several months, works great. Design moved to using onlyL0 family of parts, so decided to load the STM32CubeL0 tools. Unzipped the v1.12.0 and the v1.12.1 patch. But how to integrate with STM32CubeIDE? No instructions!
