Can I use BIOS6 IomAdapter for legacy bios5 driver

I try to use the sysbios 6 in our C6748 project and find that the PSP 01_30_01 can only support dspbios 5. After digging through the SYS/BIOS Inter-Processor
Communication (IPC) and I/O User’s Guide, I find out that the IomAdapter can provide a hook for the legacy iom driver to IDriver in sysbios6. This seems to be a rescue for the sysbios 6 user.

I create a simple hello sample project and add the IomAdapter in the RTSC configuration in xgconf and I get the following errors

I add this line "xdc.loadPackage('ti.bios.tconf');" at the beginning of the RTSC configuration script. I get the following warnings

Severity and Description Path Resource Location Creation Time Id

I cannot find any documentation to describe these warnings.

Do you know if the IomAdapter can works with the legacy bios5 PSP driver such as SPI and UART. I attached the RTSC configuration script.

Thanks,
