使用上面的设置接收fpga发送的数据,fpga一个start信号发送32768字节的数据,超过linesize的部分会丢失,想要把upp_line_size 的值调大一些,upp手册上只说明 upp_line_offset 必须小于65528(Line Offset Address (UPxD2.LNOFFSET) – The offset address between the first byte in successive lines. The line offset address cannot exceed 65528 (FFF8h) bytes, and must be aligned to a 64-bit boundary in memory (that is, the 3 LSBs must equal 0). )
是不是可以认为upp_line_size 小于65528就是可以的?
