The running thread runs vTaskDelay() as it did on the F4. It does not help. Adjusting thread priorities has little effect. Other threads (all started with higher priorities) should have plenty of opportunity to run but almost never do. It all ran...

The F4 board worked fine doing UART DMA. I start to regret this upgrade.Forget DMA and IT for now, just trying to get F7 polling working.First HAL_UART_Receive works, but the rest time out.Register analysis is unenlightening going by RM0385 referen...

Remedial register view help needed.I need to see DMA and UART registers, not having much luck.ron239955_stm1 referred to the i/o registers window, how is this done?From Debug Perspective, Registers View, I see only General Registers.I notice that the...

Compiling with a Release configuration seems to be correct because when connected via j-link, activating "Run" the console now prints "Starting target CPU" and "GDB closed TCP/IP connection" and the CPU starts. But disconnect SWIO and reset power an...

I feel like a complete ***** but darned if I can figure out how to do it.If I should be reading a tutorial somewhere let me know. Flames accepted gratefully.I am using Segger J-link, on a custom board. Debug configurations work fine, programming vi...

Finally solved the original problem. Didn't ever get the polling example going.It turned out that just _reading_ main memory from a bad location caused uart/dma registers to be reset.I didnt expect this so I didn't worry about the mem read, expectin...

The first Receive works, buffer contains good data, rc is HAL_OK, the rest time out and return with HAL_TIMEOUT with no data.Data are sent continuously. Knowledge of how the sending device works, oscilloscope, and the fact that the F4 based boardrea...

Aha. That helps.I am using an F7 chip but SFR window showed F401 which no doubt explains why the register lables didn't correspond to the chip../.settings/com.st.stm32cube.ide.mcu.sfrview.prefsreferenced svd_file_path=<long path>/STM32F401.svdHmm.re...

Hmm. Well, personally I find it frustrating that I have to say "run" to program the chip. I didn't want anything to run, I wanted to program the memory. I am familiar with the Atmel Studio software. It has a very satisfyingly distinct "program c...

Hi Mattias,Thanks for the reply. Based on your answer, for testing, another slightly different board was built with the same MCU and that one does start, so there was something up with the first one.It fooled me because it worked perfectly from Cube...

Why would freeRTOS threads which schedule properly on an F4 fail to do so on an F7? One low-priority thread steals the processor and never yields.

F7 UARTs Anything special?

How does one observe peripheral registers with CubeIDE?

1.3.0 squashes bug 64277-download-and-reset-without-gdb (thank you team). However, when disconnected from SWIO and powered-on the chip never starts.

Can STM32CubeIDE be used to program a device only? The latest revs of CubeIDE work great for dev and debugging. Now I want to turn off -g, recompile, write to device program memory and unplug. How? Can CubeIDE even do this?
