ChibiOS Free Embedded RTOS

Searching through the threads, it seems that a simulator on Linux existed in history. However, I don't find one in current version. Is it simply dropped? How difficult would it be to put this functionality back?

Ah, I see. Just as a side question, is there a way to use chprintf atomically? Or is there something that can acquire the serial bus? Or must I use other method of locking?

In the makefiles, I see the PRINTF_LIB_MIN, PRINTF_LIB_FLOAT, etc. Do I need these for chprintf to work? When I comment these out, the program compiles just fine, and the sizes are the same. The same stays true for scanf related stuff, although there is no chScanf equivalent. Actually, `chPrintf()` ...

OK, after some investigation, it looks like that those 5K are actually taken by HAL. Enabling everything in Nil config simply adds a few hundred B to the final size, so I guess that is it.

According to the documents, ChibiOS/Nil should not exceed 1KB at maximum configuration. However, when I try to compile the NIL-ARDUINOUNO demo: Size after: AVR Memory Usage ---------------- Device: atmega328p Program: 5278 bytes (16.1% Full) (.text + .data + .bootloader) Data: 555 bytes (27.1% Full)...
