Part Number:DP83822IF
硬件上,采用ZYNQ的RGMII接口,与DP83822IFRHBR连接。在板卡调试中,ZYNQ可以与DP83822通信,寄存器状态也能读到:
IEEE reg[0] = 3100
IEEE reg[0] = 3100
IEEE reg[1] = 7849
IEEE reg[2] = 2000
IEEE reg[3] = A240
IEEE reg[4] = DE1
IEEE reg[5] = 0
IEEE reg[6] = 4
IEEE reg[7] = 2001
IEEE reg[8] = 0
IEEE reg[9] = 0
IEEE reg[10] = 100
reg[F] = 0
reg[10] = 2
reg[11] = 108
reg[12] = 0
reg[13] = 800
reg[14] = 0
reg[15] = 0
reg[16] = 100
reg[17] = 12C1
reg[18] = 400
reg[19] = A01F
reg[1A] = 0
reg[1B] = 7D
reg[1C] = 5EE
reg[1D] = 0
reg[1E] = 102
reg[1F] = 0
问题是:RJ45不能与PHY建立连接。

E2E工程师已回复:
我可以问几个问题以便进一步调试吗:
•我不确定我的理解是否正确,如果我错了,请纠正我:您是在RJ45侧面临连接问题。RGMII在您的电路板上运作良好。
•如果我的理解是正确的,那么您用于连接DP83822的链接合作伙伴是什么?
•如果可能的话,你能画一个关于您设置的框图吗
May I ask couple question for further debug:
I am not sure if my understand is correct, please correct me if I am wrong.
Customer is facing an issue on the link up on the RJ45 side. RGMII works fine in customer's boardIf my understand is correct, what is the link partner that customer is using to link up the DP83822?
If possible, could you also draw a block diagram on what is customer's setup?
