The resident constant software segment cannot be reprogrammed.
Since the LIN-bus communication and some control features are
necessary for the software download.
The re-programmable software segment could be reprogrammed using
the same principle as the parameters configuration. So there is a RAM
space area up to 128 or even 256 bytes. This RAM area could be loaded
step by step using a configuration frame (similar to the one used for
parameters configuration). Each configuration frame would load four
data bytes in the RAM area. The FLASH memory with the code could be
split into areas (128 or 256). Each area could be step-by-step flashed
after the RAM space is fully loaded. This way any size of
re-programmable software segment in FLASH memory can be
programmed.
