Reset vector and Exception vector 的問題

Warning: Reset vector and Exception vector cannot be set until memory device

Why there is no answer?

在SOPC 內的CPU 元件設定中, Reset vector 與Exception vector 是必須指定的. 請先在SOPC 內加入memory compoent (如SDRAM, On-Chip Memory), 然後回CPU 設定的視窗, 選擇Reset vector 與Exception vector.

SDRAM, On-Chip Memory是在哪里找呢？

rich

On-Chip Memory:
SOPC 左手邊的System Content 視窗, Memories and Memory Controoler --> On-Chip --> On-Chip Memory (RAM or ROM)

SDRAM:
SOPC 左手邊的System Content 視窗, Memories and Memory Controoler --> SDRAM --> SDRAM Controller

建議先試試on-chip memory. memory size 設定為70K 左右. 如果quartus compile 如果報告記憶體資源不夠, 回來設成小一點的size, 如26K. 如果memory size 小於70K, 在NIOS project 內, 要把"Small C Libardy" 與 "Lightweight device diver API" 打勾, 否則記憶體會不夠.
