I'm trying to use ucc uart provided by QUICC Engine in MPC8569E, and I've checked the ucc_uart.c in linux kernel. However, I can't find the corresponding "fsl_qe_ucode_uart_%u_%u%u.bin" file in nxp's website. Seems the ucode is required only if in soft uart mode. Does anybody know if MPC8569E should use soft uart or ordinary uart? If soft uart should be used, where can I get the ucode or is there any script that can be used to generate it?
