Problem with FT232H : 32bits TX (fpga--> PC) 16 upper bits with 16 lower bits switched sometimes after a cold start

64bits transfers same problem 16bits words switched : recv 32 B (error, incrément third 16bits word) 0: 0x0018_0e15_0000_0000 1: 0x0018_0e16_0000_0000 2: 0x0018_0e17_0000_0000 3: 0x0018_0e18_0000_0000 recv 32 B (increment ok) 0:...

Problem with FT232H : 32bits TX (fpga--> PC) 16 upper bits with 16 lower bits switched sometimes after a cold start

SOLVED !!! The problem (i checked signals on acbus) during reset and configuration in fifo mode of ft232h got some glitch on rxf# (acbus0) and it starts the check-counter and...

Problem with FT232H : 32bits TX (fpga--> PC) 16 upper bits with 16 lower bits switched sometimes after a cold start

And to conclude, thanks a lot to WangXuan!!!! A lot of time saved! good good job! If interested, i'm planning to integrate everything in xilinx IP to deal directly with...

Hi, Is ok to share, i've already saved a lot of time thanks to you ;) I added this external control of stream to valid my "theory" about the cold...
