Hello everyone, I’m experiencing an issue with my Arduino Portenta H7. Whenever I upload any sketch, the red LED starts flashing in a pattern that seems to indicate a system error. I’ve tried resetting the board, entering bootloader mode (green LED pulsing), and uploading simple sketches like ‘Blink’, but the issue persists. I’ve also checked the IDE and updated the firmware, but nothing has worked so far. Does anyone have suggestions on how to proceed or insights into what might be causing this?"
