Challenge 8: "Glitch Storm"

Building on the success of the Power Trip challenge, you are once again faced with the same challenge. The goal remains the same, trigger a voltage glitch to enter a hidden code path and retrieve the flag.

However, the catch this time is that the glitch trigger is no longer the obvious SDA pin. You must discover the new trigger pin and timing to successfully glitch the device.

Your mission is clear:

1. Analyze the device to identify the new glitch trigger.
2. Precisely time and inject the voltage glitch at the discovered trigger.
3. Access the hidden code block and extract the flag over UART.

Notes

This was basically the same as the previous one. After probing around to find what was giving a clock-esque signal (it was pretty obvious) I checked with the logic analyzer:
