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.
