Hi, I have successfully booted my CM5 on the CM5 IO board from an SD card, but I cannot get it to boot from eMMC despite everything I’ve tried. I followed the official documentation for flashing the eMMC with RKDevTool from a Windows PC, but the CM5 does not reboot on its own afterwards like it should (it does reboot on its own after an eMMC flash if I have an SD card with an image plugged in, but it boots from the SD card). I even tried copying the image from the SD card over to eMMC in the system itself. Any help from those that have successfully booted the CM5 from eMMC would be greatly appreciated!
Cannot boot CM5 from eMMC on CM5 IO board
Have you also flashed the SPI image via RKDevTool?
If so then connect to the serial console to see where its getting stuck in the boot process.
Here is the serial log when I tried to boot from eMMC. I’m not too sure what it means or if it’s fixable.

Do you follow this guaid? CM5 dont have spi flash.
Hi, yes I have followed that guide, but I may have only followed it correctly on the second or third attempt (if that matters).
I am concerned that something is bricked or configured or partitioned wrong with respect to the eMMC, or that there is damage to the board. When I received it, I attached the cooler and thermal pad and screwed that on but realized the pcb was visibly bent from the pressure, so I undid the screws. I do know the eMMC storage holds something because it saved a .txt file on my desktop even after rewriting a stock image to the micro SD card.
- following the tutorial, can you recognize the Maskrom mode on rkdevtool? Do you have any logs when writing the image, can you post them
- you can boot the system with the sdcard and check if the emmc is functioning properly
Okay I appreciate the responses, I got the board booting from eMMC and figured out my silly mistake. In the instructions linked, I glazed over the hint block that says to decompress the image file before linking it in rkdevtool. I am fairly new to a lot of this and didn’t recognize that the default CM5 image XZ file type is compressed and different from the Windows.IsoFile file type (extracted) since both have a .img file extension. I think the instructions should probably list this a formal step to check instead of in a hint block, but I digress.
ok，good news.
please how can I boot it from sd card ? any help please
