Abstract: A method of updating a bootloader includes a slave controller that includes a central processing unit in communication with non-volatile memory having a shared memory architecture. The shared memory architecture including a non-volatile application memory block having application code and a non-volatile launcher memory block having bootloader code for initiating the slave controller. The method including a step of storing updated code to an application memory block of the non-volatile memory. The updated code includes a first code section having application code for application functions, a second code section having updated bootupdater code, and a third code section having image code for an updated bootloader. Slave controller receives indication to update the bootloader code stored in the non-volatile launcher memory block and then executes the bootupdater stored in the application memory block to update the bootloader stored in the launcher memory block from the image code for an updated bootloader.

Abstract: A memory architecture includes a non-volatile, application memory block having first application code for application functions capable of being called by first application, a non-volatile launcher memory block having second application code for application functions capable of being called by a second application, a non-volatile, shared memory block having shared code for shared functions, and a fixed memory locations dedicated within the shared memory block to store shared function pointers, and a volatile memory storing callback pointers. The second application code is launcher code that is operable to initialize the first application code. At least one volatile memory storing callback pointer is associated with each one of the shared functions. The callback pointers point to callback function code when the first application is executing and to callback function code when the second application is executing.

Abstract: A shared memory architecture is disclosed to support operations associated with executing shared functions from a shared memory space in such a manner that separate pieces of software can execute the shared functions.
