This thread was the power-up saga: video of hands soldering USB-C pins with glowing iron tip against the black heatsink area, vise clamping the board on a cluttered desk with CM5 module waiting. Then success—green LEDs flicker on, fans whir from headers, boot to Raspberry Pi OS CLI with green-on-black "Welcome... pi@raspberrypi:~ $" terminal. eMMC imaging hurdles hit hard (RPi docs buried, third-party gaps), USB boot saves the day for flashing, but initial attempts flop—blaming my "terrible solder job" or laptop juice, with a close-up of the suspect connector and a failed flash screenshot. By evening, eMMC's imaged via USB, booting persistently; photo of lit board with yellow Ethernet dangling. @Raspberry_Pi
called out for silence, but official guide unearthed—PCIe dreams next, no crashes on core IO at ~5W idle.
