FX3 Endpoint Configuration error - only with endpoint 6

[Anonymous]

Using SDK 1.2 I have modified the SlaveFifoSync5Bit example to use 2bit address interface with 4 Bulk endpoints, 2 IN, 2 OUT using four DMA threads

   

In file SlaveFifoSync5Bit/cyfxslfifosync.h I have altered the define statements to:

   

(In this configuration the code runs correctly and enumerates).

   

#define CY_FX_EP_PRODUCER_1                0x02    /* EP 2 OUT  */
#define CY_FX_EP_PRODUCER_2                0x04    /* EP 4 OUT  */

#define CY_FX_EP_CONSUMER_1                0x88    /* EP 8 IN  */
#define CY_FX_EP_CONSUMER_2                0x82    /* EP 2 IN  */

       

However if I use the following define statement, FX3 returns DMAChannelCreateFailed, error code 64. I can set CY_FX_EP_CONSUMER_2  to different endpoints other than 6 and it will work correctly. Why does it not work with EP6?

   

#define CY_FX_EP_CONSUMER_2                0x86    /* EP 6 IN  */

Bump:

   

I can also generate this error using end point 6 with the async example from SDK v1.2
