@wdu , hi! Can you share with us the details? Did you just write the binary to the raw flash memory? Starting at which address? I imagine at least some part of the 32MB of flash must be partitioned with a FS (jffs2?), so we must be careful not to overwrite it, right?

Can someone point me to or share the flash's map / partitioning scheme?

@Pavel-Metrokhin , can you please confirm if building the source @ https://github.com/OnionIoT/omega2-bootloader will generate the same bootloader provided @ http://repo.onion.io/omega2/bootloader/ ? In other words, is the GitHub repo complete and up to date or you build the provided bootloader from a private repo?

Thank you!
