Hello everyone,
My setup is an MX9 4K with an RK3228B chip and eMMC memory. I think I may be missing a step. I’ve already flashed the image to the eMMC and received a successful completion message. However, when I restart the device, it doesn’t boot from the eMMC. If I put the SD card back in, it boots from the SD card normally. I’ve been looking into a solution using U-Boot, but I could use some help with this.
U-boot boot order priority: first the sdcard, then the USB OTG port and eventually the internal eMMC; you can install u-boot (and the whole system) in the internal eMMC and u-boot will always check for images on external sdcard/USB first.
