I want to reflash the system of my Nano(4GB), but after I insert the SD card and use DC to supply power, there shows “No signal” on my HDMI screen(change fews different screens yet).
So what happened to my Nano? Dose it crash in bootloader stage? Shall I put the device into recovery mode to reflash the QSPI-NOR over its module?
We don’t know what happened. You can dump the log with below method.
