Hi,

And now, i trying to FX3 to FPGA data trans(FX3->FPGA slavefifo 32bit mode).
but i have some problem, so need you help.
plz, help for using FX3 to FPGA data trans mode.
FX3 to FPGA data trans setting code is below.
dmacfg.prodSckID = CY_U3P_UIB_SOCKET_PROD_1 (0x401)
dmacfg.consSckId = CY_U3P_PIB_SOCKET_0 (0x0100)
dmaCfg.prodHeader = 0;
dmaCfg.prodFooter = 0;
dmaCfg.consHeader = 0;
dmaCfg.prodAvailCount = 0;
And FX3 J5(CTL11), H5(CTL12) PIN is low signal.
CyU3PDmaChannelCommitBuffer function operation, but data is not output.
(I captrued the oscilloscpe, FX3 data0 PAD, And FlagA, FlagB signal is capture successed)
So, can you some advise?

Hi,

   

Did the commitbuffer API return an error? If so which one?

   

Are you getting any PIB Buffer underrun errors?
