Hello I am trying to use BCACHE_setSize and BCACHE_wbInvAll in my code.

I am using CCSv5.1 on windows.

While linking the code I am getting following error.

unresolved symbol

_BCACHE_setSize

_BCACHE_wbInvAll

I think I am missing to include some lib file. But I am not sure which one to include.

Can anyone please help me in this?

Regards,

Mike

Hi Mike --

Which device are you using? The BCACHE APIs are only available for the 64x+ and 674x+ devices (not the 64x or others).

Can you send across the 'loadPlatform' line in your .tcf file?

Thanks,
-Karl-

Raf,

For SYSBIOS you should be using the ti/sysbios/family/c64p/Cache module. Why are you using BCACHE? Are you using the legacy APIs? I would still recommend you to move to the Cache APIs if possible.

BCACHE_setSize is not supported in SYSBIOS 6.34.xx.xx - you need to use the Cache version of this.

Because I have an example from TI and there are BCACHE functions.

Did that example come from SYS/BIOS 6.34.2.18?

Of course not but I don't have another.

Can you post the code snipet?

Replace BCACHE by Cache. BCACHE is a DSP/BIOS 5.x API not SYSBIOS 6.x API. Wherever you got that example...its old and needs to be updated to the new APIs.
