15 years agoI have replaced the DDR2 memory with on-chip memory (262144 bytes), but the issue somehow was 125MHz clock. I have set the 50MHz clock instead and the Nios started.
The 125MHz clock was running for sure, I have made a blinker which works either with 125MHz clock or with 50MHz clock. The development board is Cyclone III Host board from Altera (2 clocks on board + SMA IN) Now the strange problem is that the console doesn't show anything. It runs the CPU: --- Quote Start --- Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x00081030: verified Initializing CPU cache (if present) OK Downloading 00040000 ( 0%) Downloading 00045CD0 (71%) Downloaded 24KB in 0.4s (60.0KB/s) Verifying 00040000 ( 0%) Verifying 00045CD0 (71%) Verified OK Starting processor at address 0x00040184 --- Quote End --- I've checked BSP parameters, the stdin/stdout/stderr are all set to uart_jtag, but the console screen is empty.
