Linux/AM3359: DDR3 Leveling

Shivasharan Nagalikar

Part Number: AM3359

Tool/software: Linux

Team,

One of my customers using Am3359 with the MT41J128M16JT-125, 1600 Speed bin (https://www.micron.com/parts/dram/ddr3-sdram/mt41j128m16jt-125 ). With the following settings they are able to get the levelling done but DDR test is failing. They also have referred to( https://e2e.ti.com/support/processors/f/791/t/469075?AM335x-DDR3-400MHz-SW-leveling-issue)

#define ALLOPP_DDR3_READ_LATENCY    0x00100008
#define ALLOPP_DDR3_SDRAM_TIMING1   0x0AAAD4DB   //0xEAAAE4E3
#define ALLOPP_DDR3_SDRAM_TIMING2   0x28377FDA   //0x266b7FDA
#define ALLOPP_DDR3_SDRAM_TIMING3   0x501F833F // 0x5F7F867F

#define ALLOPP_DDR3_SDRAM_CONFIG    0x61A05282 //0x61C05932

#define ALLOPP_DDR3_REF_CTRL        0x00000C30 //400 MHz * 7.8us
#define ALLOPP_DDR3_ZQ_CONFIG       0x50074BE4

Optimized values after leveling:

#define CMD_PHY_CTRL_SLAVE_RATIO       0x80
#define CMD_PHY_INVERT_CLKOUT          0x0

#define DATA_PHY_RD_DQS_SLAVE_RATIO    0x38
#define DATA_PHY_FIFO_WE_SLAVE_RATIO   0xAA //RD DQS GATE
#define DATA_PHY_WR_DQS_SLAVE_RATIO    0x31
#define DATA_PHY_WR_DATA_SLAVE_RATIO   0x63 //WRITE DATA

#define DDR_IOCTRL_VALUE               (0x18B)

Couple of other observations:

1. With above settings + configuring the DDR PLL to 400 Mhz the levelling reurtns all ZEROs. So currently setting pll as :DDR_PLL_Config( CLKIN, 23, 303, 1);

2. If I hit the continuous refresh the values gets updated always.

OUtput of the Data Integrety test:

Any pointers ?

Here are the tracelength details:
Trace Length (inches)
Byte 0 Byte 1
DDR_CK trace 1.683 1.683
DDR_DQSx trace 1.38 1.38

Shiv, since you have a point to point design, you should be able to use the results of the RatioSeed spreadsheet straight away, without running the software leveling algorithm. Please follow these steps:

1. Enter the trace lengths in the Ratio Seed spreadsheet as you have done. Use 400Mhz for frequency and INVERT_CLKOUT=1
2. Use the resulting values from the spreadsheet in the GEL file. Ensure you have all the slave ratio values from the spreadsheet copied into the GEL, including INVERT_CLKOUT. And change the DDR PLL frequency back to 400MHz. Also, increase READ_LATENCY by 1 (in your case, change LSBs to 9)
3. Run the tests as you have described below.

Let me know results...

Regards,
James

Shiv, it looks like it may be a timing issue. I used the timing spreadsheet with the datasheet you pointed to, and it looks like you used the wrong value for tRFC. It looks like you used a value of 130ns, but it should be 160ns based on the datasheet. This changes a couple of values:

#define ALLOPP_DDR3_SDRAM_TIMING1 0x0AAAD4DB
#define ALLOPP_DDR3_SDRAM_TIMING2 0x28437FDA
#define ALLOPP_DDR3_SDRAM_TIMING3 0x501F83FF

Can you try with these?

Regards,
James
