ABSTRACT:
A field-reprogammable storage control device has a microcontroller, a write-protected memory which contains a boot code for the storage control device, a rewriteable memory for application code executable by the microcontroller, and a jump function located in both the write-protected memory and the rewriteable memory for movement between the write-protected memory and the rewriteable memory for recover after a processing interruption. The storage control device remains operational using the write-protected memory and the boot code while receiving a new application code from a remote site.
