TDA4VM: All firmware is required for tda4 to function properly？

Hi Experts:

            because i don't use c66_1,so I

1， delete c66_1_fw in / lib / firmware,

2，on vision_apps\apps\basic_demos\app_tirtos\common\app_cfg.h,  not define ENABLE_IPC_c6x_1.

3，disabled the c66_1 node on kernel dtb.

when i run the  the encode test ,it printf below, but while then have c66_1_fw,it work ok.
