problem booting SparkFun Pro RF - LoRa, 915MHz (SAMD21) without USB attached

Development Boards
1

everything works fine if my device is connected through its usb port to my computer.

if I try to boot it without being connected, the bootloader seems not to load my program

doesnt seem to be my code trying to use USBSerial on boot

did a minimal program (just blinks the blue led) and it still hangs if without the usb cable :frowning:

2

Guess I found the culprit. Sees that the compiler and linker were including the SerialUSB library, even if my source code had all the references to SerialUSB disabled by conditional compiling !!!

managed to find this by turning on compiler verbose … “Detecting libraries used…”

3

Still not sure what triggers this, seems to be an IDE issue. Sometimes the USB module gets linked together, even when no usb function is called from the program.

4

can you share your sketch? Try compiling an empty sketch and see how much USB is included already. As such I don’t expect Including the SerialUSB driver should not be an issue .

5

this is exactly my point. seems to be an IDE issu. here is what I did for the following output: started the IDE from scratch, created a new sketch and compiled it. Note that the USB modules got compiled, although I’m not invoking them. Not sure if the compiled modules are getting linked together though.

when I change my preferences.txt file to

cache.enable=true

compiler.cache_core=true

the outcome changes though - First compilation is full, then after it the unused modules seem to be unused.

Not much I can do with this information. Looks like a “normal” compile to me. There are a lot of software that is part of core which is included always (even with an empty sketch). Can you share the your sketch ? Personally it happened more than once to loose a lot of time on a small typo.

7

I guess I found it !!

I changed my source code with the following conditional compiling to remove the serial output when I wished. Well, seems that the SERIAL definition happens also somewhere else :slight_smile:

#if defined(SERIAL)

/home/paulohm/Arduino/lora1/lora1.ino:41:0: warning: “SERIAL” redefined [enabled by default]

Only got this because I turned on compile warnings

8

In other words, the serial source code was always being included, especially …

#if defined(SERIAL)

SerialUSB.begin(115200);

// Serial communication on startup is not consistent on the SAMD21. The

// following line waits for the serial monitor to be opened before

// continuing. Uncomment if not needed.

while(!SerialUSB);

SerialUSB.println(“Starting”);

#endif
