CCS811 bricked??? about ccs811

Hi John,

I need some more clues to solve this.

If you inspect the ino file, the setup() function, you see

  // Flash
  Serial.print("setup: starting flash of '");
  Serial.print(image_name);
  Serial.println("' in 5 seconds");
  delay(5000);
  Serial.println("");
  ok= ccs811.flash(image_data, sizeof(image_data));

so after the message setup: starting flash of 'CCS811_FW_App_v2-0-0.bin' in 5 seconds the flash() function is called. That function starts as follows.

bool CCS811::flash(const uint8_t * image, int size) {
    ...
    wake_up();
    // Try to ping CCS811 (can we reach CCS811 via I2C?)
    PRINT(F("ccs811: ping "));

This means that after the message setup: starting flash of 'CCS811_FW_App_v2-0-0.bin' in 5 seconds the you must see ccs811: ping ok or ccs811: ping FAILED.

If you don't get that, something very funny is going on.
