I found the reason why RedBoot didnt work in ROM startup.
there was a line missing in the memory layout file *rom.ldi
CYG_LABEL_DEFN(__reserved_vectors) = 0; . = CYG_LABEL_DEFN(__reserved_vectors) + 0x3000;
CYG_LABEL_DEFN(__reserved_vsr_table) = ALIGN (0x1); . = CYG_LABEL_DEFN(__reserved_vsr_table) + 0x200;
missing --> CYG_LABEL_DEFN(__reserved_virtual_table) = ALIGN (0x1); . = CYG_LABEL_DEFN(__reserved_virtual_table) + 0x100;
SECTION_data (ram, ALIGN (0x10), FOLLOWING (.gcc_except_table))
so the virtual table was polluting the stack (or vice versa).
