S32R45:Whether the DDR speed meets the requirements?

[Shi_test]

Has anyone encountered this problem?

    On the basis of "RSDK_Multi_RFE_example_S32R45" I tried to run 1024-512-16 range with RF and SPT ( The output data format is "CP4Q_FMTA" ) . I found it OK to put the processed data on SRAM. But if i want to put the processed data on DDR it will not succeed. Because SPT does not return the completion callback "SptEcsIsrCb".  So I wonder if it is possible that the DDR speed is not as fast as the SRAM, causing the loss of chirp?
