ESP32 Wroom32 reliability problem? I have 10pcs in two applications on two HW. Out of 10 new 1pcs at ESPTools 3.5.7 arduino IDE reports "Warning: Could not auto-detect Flash size (FlashID = 0x0, SizeID = 0x0), defaulting to 4MB" which is defective Flash. On the second piece, the FW webupdate reports "Guru Meditation Error: Core 1 Panic'ed (IllegalInstruction). Exception was unhandled. Memory dump at 0x4014e850: Bad00Bad Bad00Bad Bad00Bad Guru Meditation Error: Core 1 Panic'ed (Unhandled debug exception) Debug exception reason: Stack canary watchpoint triggered Guru Meditation Error: Core 2 Panic'ed (Guru Meditation Error: Core 2 Panic'ed (Double exception) " which is a problem again with FLASH, but FW can be loaded via Arduino IDE other pieces work fine. How to solve it? The failure rate is 20% which is enough. What is your experience?
