My Mtx Cyclone Board Has Bug, need Mtx help.

Hello,

Now, I have used the Microtronix Cyclone Board nearly two months. During Using, I found bugs with my board.

My SW is Quartus II 4.2 SP1 + Nios II 1.1 Eval + uClinux V1.3.

1. altera_avalon_new_sdram_controller can not work with Nios II s/Core, but can work with Nios II e/Core.

I do know why and how to deal with. I just use the old sdram_controller(SOPC Builder 2.7) instead and the old one is OK.

2. Also, I use old sdram_controller + Nios II s/Core + Flash + epcs_controller + other pio. I can build the uclinux kernel and run it properly. But When I add the EMAC, it can not run. Even it can not run Nios II IDE software examples such as hello_world. I use debug as, and the pointer stay at the beginning of main() all the time.

3. I have checked the example "kitchen_sink" in Mtx Cyclone1_3.zip. I found that in the example, Mtx unconnect the sdram slave port from the data_master and instuction_master of cpu. So, CPU can not access to sdram, only use sram. I do as the example, hello_led can run. When I reconnect the sdram to the data/instruction master, it can not run again.

Does Mtx do it to avoid the bugs on My Cyclone board? I hope it is not so. Or maybe it is my fault.

Whether or no, it is the bug of my Mtx Cyclone Board, can Mtx help me to deal with them?

I want my board to run the components and uClinux fully.

Thank you.
