Reading data fails on the 16 Bit slave fifo interface
I am trying to read data on the slave fifo interface. As can be seen on the first page of the attached pdf, the first read attempt succeeds and is stopped after flag A (empty/full fixed to thread 0) indicates fifo empty.
On the second page an example is shown, where data is read using two read accesses. The first access works good, while during the second access the data lines get stuck at 0x0000.At the same time flag A gets stuck high until I reset the FX3 chip. The clock frequency is only 10 MHz.
