I watch boot process in uart console, stop boot process on key press, sequential load a board system. Also watch reflash process. And I want to suggest some improvements. 1. Make better process of reflash firmware: if usb stick contains files: bluecore.audio emmc.uImage rescue.emmc.dtb rescue.root.emmc.cpio.gz_pad.img install.img Then load rescue system from usb stick, it necessary to restore firmware when a partition table or partitions on emmc is broken. Make load it in first bootloader U-boot by pressing Esc and type "goru" command. 2. init ip config and ssh console when load rescue linux from usb.
email @freeroc with this suggestion, will probably have a better chance of geting heard. email in his signature.
Thanks, I think your thought is reasonable. I have forward your advice to R&D related engineers. You will be informed if there are any progress.
