We are using U-Boot 1.1.4 on a MIPS 74Kc QCA 9557 processor, which is running Linux Kernel 2.6.32.27. We have a situation were our firmware keeps hanging due to some issues. We are looking into a solution where U-boot and Kernel keep communicating with each other every some minutes. If U-boot finds that there is no communication, it will reset the board. > > I understand that once the Linux Kernel is booted, the bootloader is not there anymore.
