I downloaded the latest AI64 board image which automatically loads the OS into eMMC. I burned the image into micro SD and inserted into the SD card slot of AI64. After powering it on, the LEDs were scrolling left and right indicating that the image is being transferred into eMMC. After the transfer is done, the bottom LED (Wkup UART0) was lit. Then I removed SD Card and the power and applied the power again. Nothing happens, the bottom LED is lit only. I wanted boot from the SD card, but only the bottom LED stays lit. The AI64 is now totally unresponsive.
I even tried holding BOOT + RST button and applying power then releasing the RST. Waited for lights to turn on, only the bottom LED stays on. I released the BOOT button, no change.
I held the boot + rst button and then plugged in power. The bottom LED lit as before. No other activity on the LED is noticed. I held it for several minute then let go the boot. Didn’t boot. Cannot ping or ssh to debian@192.168.7.2
Try a different SD card, some of those cards are flat out junk. I bought some 64 Gb ones factory sealed and appeared legitimate. None of them work. 32 Gb from same company and they work.
Also make sure to eject the SD card from host, not just remove it.
Thanks Robert, v11.5 image which you provided did boot and i was able to flash the emmc. But, there is no hdmi output. Does this image have graphical desktop ?
