Arduino for STM32

The Quad-SPI memory interface also has a Memory-
mapped mode.

Well, I was wrong about that one!
I did not see an example up on github that showed that magic, but I only spent maybe 15 minutes rambling through the code.

... So what to do, the Daisy Seed has 8MB of external flash, that should be useable to store a lot of presets . ... The external flash is QSPI, so is not memory mapped for access by the linker ... at least through no trick that I am aware of... So, you can likely move lots of strings and config int...

I do not purchase new notebooks ... like expensive cars, they depreciate too quickly. My development notebook is an older i7 HP EliteBook and it came with a 5400 RPM commodity drive - I replaced that immediately with a (at that time) fast 480GB SSD ... that was years ago. The SSD has been good, no e...

... but as far as I can go is 1 or 2KB, still far away from the 19K. Since I'm using Arduino IDE, I adopted the recommended board configuration, but with "-Os" compiler option to shrink the code. ... I honestly do not understand your obsession to the code size. You did not publish your sk...

LTO options were removed 3 years ago in the LibMaple (Roger's) core:

I have no info about the STM32duino Official core.

One of the original scripts: https://forum.arduino.cc/index.php?topic=182849.0 Another oldie to clone chip firmware: https://forum.arduino.cc/index.php?topic=177898.msg1320206#msg1320206 And one for memory usage: https://forum.arduino.cc/index.php?topic=196101.0 The above are obviously in need of re...

Many years (9+) ago, I concocted a Windows 8.0 batch program to move compiled Arduino 1.0 files around my Win machine. I had forgotten about it, so I sat down on a Win 10 box today and created a short batch script (one could PowerShell too) to simply make a record of where the existing ELF file was ...

... it doesn't make sense to rebuild each time the /tmp folder is cleared ... I suggest it makes perfect sense as the temporary files are bound to a specific IDE sessions ... For example: 3 IDE sessions and 3 set of files are separated neatly in subdirectories beneath /tmp Close any IDE session and...
