你好
我在使用MIG CORE读取LPDDR内存时遇到问题。 我已经成功发送CMD命令,并且空信号已经返回,但是,我没有成功发送读命令,空信号没有切换到“0”... 在atchment,我已经发布了数字振荡器和StateMachine的捕获来控制MIG,我使用的是LX9 Microboard。 D0信号是我的状态机控制MIG的启用信号 D1信号是StateMachine(WAIT)的返回 D2是cmd_en信号 D3是cmd_en信号的cmd_empty返回值(接受cmd) D6是wr_en信号 D7是rd_en信号 D8是wr_en信号返回的wr_empty信号(wr接受) D9是rd_empty信号 观察振镜图像,不报告rd_empty信号,但报告了wr_empty信号。 任何消化来解决我的问题? 谢谢你的帮助!

I have sucess on send CMD command, and the empty signal has returned, but, i don`t have sucess to send read command, the empty signal not switch to "0"... In atchment, i have posted a capture of digital osciloscope and the StateMachine to control the MIG, i`m use a LX9 Microboard. D0 signal is the Enable signal for my State Machine to controll the MIG D1 signal is a return of the StateMachine (WAIT) D2 is the cmd_en signal D3 is the cmd_empty return of the cmd_en signal (cmd accepted) D6 is the wr_en signal D7 is the rd_en signal D8 is the wr_empty signal returned of the wr_en signal (wr accepted) D9 is the rd_empty signal Observing the osciloscope image, the rd_empty signal is not reported, but, the wr_empty signal has reported. Any sugestion to solve my problem? Thanks for any help! DATA_RAM_Control.txt 8 KB |
