symptom | The same board produced working hardware JPEG on one day and none at all two days later, surviving reboots, reflashes and driver reinitialisation in between. Measured cleanly: 10 consecutive JPEG capture failures across QVGA, VGA, SVGA and UXGA over about 15 minutes and two separate scripts — then a POWER CYCLE, then 35 or more consecutive successes, including a verbatim re-run of the script that had just failed ten times. Five deliberate attempts to re-trigger the failure afterwards all failed. |
