Hi all,

How SC589 to use the library of 21489 in cces? As we know 21489 can use the library of 21375 in vdsp, why SC589 cannot use the library of 21489 in cces now?

Hi Alan,

To use the library of ADSP-21489 in the ADSP-SC589, can you please try changing the char size setting in the compiler( Project properties -> C/C++ Build -> Settings -> Tool settings -> Crosscore SHARC C/C++ compiler -> processor - > change the char size to (32-bit(-char-size-32))-word addressing mode.

Please note that ADSP-21489 does not support byte addressing mode, it only supports word-addressing.

For more details about byte addressing and word addressing mode, please refer the compiler manual for SHARC processors from the below link.
