Hello Chury,
The “ERROR L1102: Out of allocation space in segment ROM at address 0xFFFC86” told you that there isn’t enough space at ROM segment.
You may change ROM segment size.
Please edit bootloader-persistent.prm or bootloader-rewritable.prm file for increasing ROM segment size (according to your built configuration – per Figure 4).
If you will change bootloader size for example to 16kB (0xFFC000 TO 0xFFFDFF;), you should also check/modify your BL_FPROT settings in Config.h. Of course, this change should also propagate into your application linker file (ROM will be there only up to 0xFFBFF7)
Or, you may change Optimization level – this may save several bytes. On another side, the project debugging may be tricky with such feature.
If you will use S12ZVL32 instead S12ZVL128, you should edit FLASH_START_ADD definition in Config.h. Of course, also the main application project linker file must reflect that derivative change…
Please be aware that S12ZVL32 has just 1kB of RAM. In that case, we cannot use this bootloader in rewritable built configuration.
If your modified bootloader will use any derivative specific registers (like physical layers, HVI inputs,…), you should also change original mc9s12zvl128.h and mc9s12zvl128.c files per your derivative. See chapter 3.2
I hope it helps you.
Best regards
Radek
