Happy too early.
It doses not work after a reset or power off.
It works only after upload. I use the Bootloader 2.0

I'm seeing something similar with the 1.8.0 core on Ubuntu, after uploading a sketch the board never shows back up as /dev/ttyACM0, so I cannot open the Serial Monitor.
To upload the sketch again I have to hit RESET right after selecting Upload.
I can then switch to Roger's core, upload a sketch using the above method and the board magically shows back up as /dev/ttyACM0, and works fine after that.
I thought the STM core worked before I updated to the latest release.

Honestly, I'm not able to reproduce your issue.
I will made some other try.
I see last week, that the bootloader have a regression and Roger made a patch.
So it could be fine to test it.

it is not clear to me what this has to do with the bootloader.
I have testet it with the same bootloader on rogers core, it also works after a reset or plug off and on.

I use this sketch:
Code: Select all
int8_t led = 0;
#define csPin 7
#define csPin2 31
void setup() {
pinMode(csPin, OUTPUT);
pinMode(csPin2, OUTPUT);
digitalWrite(csPin, HIGH);
digitalWrite(csPin2, HIGH);
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
if(Serial.available()) {
char c = Serial.read();
Serial.print("hello ");
Serial.print(c);
Serial.println();
}
led = ~ led & 1;
digitalWrite(LED_BUILTIN, led);
delay(100);
}
At SPI1 and SPI2 I have connected a CC1101 an a LAN Modul. can this matter?

You can simplify the led line to
If led is 0 then 1 - led = 1.
If led is 1 then 1 - led = 0.

Hnestly, I don't know why this not work.
Maybe an issue with the reenumeration.
You can try to change the USBD_ENUM_DELAY value which is set to 10 ms by default.
