Loading Firmware
(principle)
In the very first beginning a Firmware is released by development. After that the
Alpha test will check the firmware in a Flash controller. Since Eprom controller are
not supported only the Flash version will be checked and released by Alpha test
department. Afterwards the firmware will be distributed via Competence Center in
form of a FLASH File (for flash memory) and mostly as a BINARY file (for eprom).
A never initialized FlashMemory has to be burned once then the Bootstrap-Loader is
resident in the memory. From then on the Memory is ready to being flashed.
(Character set) needs not to be initialized first since the bootstrap loader remains in
the firmware socket).
Please see a chart which intends to clear up the actual situation:
