如何解决DE0-Nano的EPCS16 无法下载的问题:NO EPCS LAYOUT DATA --- LOOKING FOR SECTION [EPCS-XXXXXX]
在用NIOS的flashprogram对EPCSx进行烧录程序时,出现了No EPCS layout data --- looking for section [EPCS-XXXXXX]的错误,在网上查找了一下,解决办法如下。
1、首先在<nios2_install>/bin文件夹下面新建nios2-flash-override.txt文件;
2、输入下述代码,下面描述的器件都是Altera的EPCS器件,sector_size表示sector大小,sector_count表示sector个数;
[EPCS-202011] # EPCS1N (lead-free)
sector_size = 32768
sector_count = 4
[EPCS-202013] # EPCS4N (lead-free)
sector_size = 65536
sector_count = 8
[EPCS-202015] # EPCS16N (lead-free)
sector_size = 65536
sector_count = 32
[EPCS-202017] # EPCS64N (lead-free)
sector_size = 65536
sector_count = 128
3、在上述代码中添加自己选择的通用SPIFlash,我用的是DE0-Nano板子,上面的EPCS是EPCS16
[EPCS-010216] # EPCS64N (Spansion-lead-free) S25FL064P
sector_size = 65536
sector_count = 128
sector_size和sector_count可以从所用的FLASH手册查找。
