Board 0001 doesn't configure a working FPGA
Board 0001 has problems...
I've observed difficulty accessing the attached flash. Once the flash has finally been programmed, I've observed errors whilst the flash configures the FPGA, like these:
- [Xicom 50-38] xicom: Device:0, user chain number:1, slave index:0. Reading intermittently wrong data from core. Try slower target speed. Make sure design meets timing requirements.
- [Xicom 50-38] xicom: Device:0, user chain number:1, slave index:0, is not a valid CseXsdb Slave core.
- [Labtools 27-3176] hw_server failed during internal command. Resolution: Check that the hw_server is running and the hardware connectivity to the target
But the other three prototypes have worked correctly, with the same flash settings and same configuration files (.mcs and .prm).
In addition, if the FPGA is programmed directly (e.g. impact, chipscope), the FPGA doesn't respond to basic VME accesses, like for example, reading the HWVER register...
