FireBeetle system panic when trying to set pinMode()

I've been having far too many inexplicable problems with the FireBeetle and decided to reduce everything down to as simple a situation as I could. I wanted to turn every IO pin on and off about once per second, so I could just see if they even work. Long story short - they don't.

If I run the following, I get a panic when I try to set the pinMode on different pins. If I change the order of calls, the pins cthat cause the panics change. The pins that are commented out are pins that have caused panics in the past, but if I put those same pins at the beginning of the list, they pass and others fail.

What the hell is wrong with this hardware? I get the same behavior from 4 different dev boards.
Code: Select all
#define NUM_PINS 24 int pins[NUM_PINS] = {35, 1, 25, 26, 27, 9, 10, 13, 5, 2, 6, /*7,*/ 8, /*11, 36, */ /*39, 34,*/ 3, 15, 18, 23, 19, 21, 22, 14, 12, 4, 16, 17}; void setup() { delay(1000); // put your setup code here, to run once: Serial.begin(115200); pinMode(34, OUTPUT); for(int i=0; i<NUM_PINS; i++) { Serial.print(i); Serial.print(" "); Serial.println(pins[i]); Serial.flush(); pinMode(pins[i], OUTPUT); Serial.println("done"); Serial.flush(); delay(250); } pinMode(LED_BUILTIN, OUTPUT); } bool state = false; void loop() { // put your main code here, to run repeatedly: state = !state; for(int i=0; i<NUM_PINS; i++) { //digitalWrite(pins[i], state?HIGH:LOW); } digitalWrite(LED_BUILTIN, state?HIGH:LOW); Serial.println(state); delay(1000); }

2021-08-31 21:39:10 What got this started is that a number of pins (9, 36, 39, to name a few) don't work as GPIO pins - at all. None of the four boards I have will blink an LED with:

Code: Select all

 void setup() {
  pinMode(36, OUTPUT);
  pinMode(LED_BUILTIN, OUTPUT);
}
 
bool state = false;
void loop() {
  state = !state;
  digitalWrite(36, state?HIGH:LOW);
  digitalWrite(LED_BUILTIN, state?HIGH:LOW);
  Serial.println(state);
  delay(1000);
}

If there's an explanation that gives me a workaround, I'll be happy to hear it, but it's going to be way outside the bounds of what's normal for Arduino. I think I'd rather just send everything back to Mouser than work with hardware I can't trust. foodini
