Re: SerialUSB doesn't work on Maple Mini
Try with Serial.begin(115200); while (!Serial) { yield(); } in setup. I had few troubles also with usb serial on stm32duino core, and that line fixed that. Annoying part is only that sketch won't continue untill there is working serial communication with PC. Also, for me, when board is unplugged, i ...

Re: Interesting problem
Well, your board works ok, it's software issue that you can't connect. Only way to make it work without software modification is to press "connect" in same time you power on your board (if possible). Maybe, if you can, get blue pill dev board, so, untill you find solution, experiment on bo...

Re: Interesting problem
Error "No ST-LINK detected!" i get only when i disconnect st-link v2 dongle from USB and try to upload from Arduino IDE. Maybe missing drivers, maybe st-link v2 is stuck in DFU mode, maybe core or Arduino IDE need to be updated. I don't understand what BOOT0 have to do with ST-LINK Utility...

Re: Interesting problem
What error Arduino IDE report? - "No ST-LINK detected!" - "No target connected. Unable to connect to ST-LINK!" - "Unable to connect to the MCU device!" Also, when using STM32 ST-LINK Utility, when you click "connect to target", does it connect or you get error...

Re: Interesting problem
Maybe not related, but got to ask. Do you have STM32F103C8/B chip or chinese clones like SK32F103C8 or GD32F103C8? But i agree with others, if you are compiling with Arduino IDE, and using Roger's core, why not upload from Arduino IDE? In my experience, uploading with st-link needed reset only when ...

Re: Interesting problem
In your code, do you use pins PA13 or PA14? (SWDIO and SWCLK) Or in some way set them as inputs/output (individually or as portA manipulation). Maybe it's in conflict with st-link's pins.

Re: Use timer for precise interrupt
You also need
in your setup.
Code: Select all
timerBase->setMode(1, TIMER_OUTPUT_COMPARE); // 1 is channel number 1, can be 1,2,3 or 4 - Sat Dec 28, 2019 9:49 pm

Re: LTO isn't working?
In my experience, since I have some project that include both interrupts and timer, LTO was working on 1.7.0 core version. You try to downgrade from board manager and test it. And, for me, O3 with LTO produce much faster code then with just O3 (when measured with logic analizer).
