Hello,
I have two fx3 in communication in GPIF port.
One is in master state machine, base on master given on GPIF designer and we had a third thread.
the other on slave state machine. identically to sync slave fifo 2bit
FX3 master has 2 threads which push data to FX3 slave reading Thread (only one thread).
FX3 master thread configuration: - dma channel thread 2 : CPU -> PPORT (consumer) in manual out. buffer size 512, buffer count 16.
- dma channel thread 1 : USB -> PPORT (consumer) auto chanel. buffer size 1024, buffer count 8.
- dma channel thread 0 : PPORT (producer) -> CPU manual in. buffer size 512, buffer count 16.
FX3 slave thread configuration : - dma channel thread 0 : PPORT (producer) -> CPUbuffer size 1024 , count 3 CPU -> USB (manual), buffer size 1024 , count 4.
- dma channel thread 1: USB -> PPORT (consumer) auto, buffer size 512, count 8.
What I want to do is sending data from master to slave FX3.
FX3 master threads 1 and 2 send data to FX3 slave thread 0.
THREAD 1-----|
FX3 master | ------> THREAD 0 FX3 slave
THREAD 2 ----|
I can actually make only working one by one but not both at the same time.
My state machine give the priority to thread 1. :: IDLE -> THREAD1 -> THREAD2 -> goback to IDLE
So does any body aware on threading in GPIF Port to help me please?
