SYSBIOS - question on SYSBIOS PMI lib for C674x and SYS/BIOS SDK for C6748

Other Parts Discussed in Thread: SYSBIOS, TPS650250

Team,

-The following library seems to be LCDK board is also has support PMI (Power management interface) but not sure.
C:\ti\bios_6_45_xx_xx\packages\ti\sysbios\family\c674\pmi\lib\release\pmiLib_lcdk.a674
C:\ti\bios_6_45_xx_xx\packages\ti\sysbios\family\c674\pscl\pscl_config_lcdk.c
Could you please confim that the SYSBIOS PMI is being validated on the LCDK board and currently supported?

-How does the SYSBIOS PMI lib plays together with the rest of the C674x BIOSPSP from the SYS/BIOS SDK for C6748 (BIOS_C6SDK v2.0):
http://www.ti.com/tool/biossw-c6748Are the low power mode (using the PMI lib) tested as well in the SYS/BIOS SDK for C6748 on the LCDK?

Thanks in advance,

Anthony

Anthony,

The PMI and PSCL libraries were indeed tested on the LCDK board. On the LCDK only frequency scaling was supported, voltage was fixed at 1.3v. See processors.wiki.ti.com/.../Power_Module_for_C6748_and_OMAP-L138

So… because voltage was fixed, there was no communication with the TPS650250 on the board, as you asked about on another thread.

If you have questions about usage with BIOSPSP or BIOS_C6SDK those should be posted to the device forum.

Regards,
Scott
