Hello all, I'm a computer engineering student at the University of Michigan. I'm trying to use the Milkymist DMX TX core in a class project on an Actel ProASIC FPGA, but I'm running into a strange issue.
When I write any value to an address between 0x200 and 0x3fc in the DMX TX core (via the CSR bus), the core completely stops transmitting. Once the core goes into this state, I can still read and write addresses below 0x200, but whenever I read any address above 0x200, I get a 0, regardless of what I write. Additionally, even while the core seems to be transmitting properly, any reads from addresses 0x400 - 0x7fc in the core return 0, regardless of what I write. I'm using the latest version of the core from Github, clocked at 25 MHz. If anyone could provide any hints or pointers, I'd appreciate it!
