Where EDMA LLD error codes are defined

Hi,

I'm trying to do some DMA transfers, but I'm getting these errors:

edma3_test: EDMA3_DRV_enableTransfer Failed, error code: -139
edma3_test: EDMA3_DRV_freeChannel() FAILED, error code: -139

Where do I find the definition of the error codes (the possible values and thei meaning of EDMA3_DRV_Result)?

Thanks

    Hi Johns,

    As you know you have the EDMA LLD in source code so you can find the function EDMA3_DRV_enableTransfer in the file edma3_lld_02_11_05_02\packages\ti\sdo\edma3\drv\src\edma3_drv_basic.c and the function return values in edma3_lld_02_11_05_02\packages\ti\sdo\edma3\drv\edma3_drv.h "/** @brief EDMA3 Driver Error Codes Base define */" and -139 is (EDMA3_DRV_E_BASE = -128) -

    #define EDMA3_DRV_E_INVALID_PARAM               (EDMA3_DRV_E_BASE-11)

    Thanks,

    HR
