After I finish create environment and testing, I tell my college to copy image, he copied image. When I Try to boot no matter the Original One or the copy one .Booth can’t start ,only show up the logo than black screen, but the light still on and gpu still heating but no fan. I though it is about the SD card so I remove and pug in another sd that work on another device, but it still have same problem. When I think it is about the hardware, I remove the sd card than pug it back to the one should work however now it also have same problem. The more I switch to test it spread like virus. I am so lost
Try to enable serial console. Otherwise you are just doing blind debug which you don’t know what you are doing there.
