Tool/software: Code Composer Studio
Hi,
I am using a customized board with AM3359 , DDR3 Chip (MT41J128M16JT-125) based on the Sitara ICE v2 and are operating the DDR3 at 400 MHz operating speed .
I have attached the Customized GEL file along with the DDR3 Register calculation sheet, DDR3 Phy Calculation scheet.
I am following the instructions from the wiki: http://processors.wiki.ti.com/index.php/AM335x_DDR_PHY_register_configuration_for_DDR3_using_Software_Leveling
But the S/W leveling only reports zeros:
Enter the PHY_INVERT_CLKOUT value (0 or 1) from the spreadsheet
0x0
Enter the Seed RD_DQS_SLAVE_RATIO Value in Hex to search the RD DQS Ratio Window
0x40
Enter the Seed FIFO_WE_SLAVE_RATIO Value in Hex to search the RD DQS Gate Window
0x74
Enter the Seed WR_DQS_SLAVE_RATIO Write DQS Ratio Value in Hex to search the Write DQS Ratio Window
0x0
***************************************************************
The Slave Ratio Search Program Values are...
***************************************************************
PARAMETER MAX | MIN | OPTIMUM | RANGE
***************************************************************
DATA_PHY_RD_DQS_SLAVE_RATIO 0x000 | 0x000 | 0x000 | 0x000
DATA_PHY_FIFO_WE_SLAVE_RATIO 0x000 | 0x000 | 0x000 | 0x000
DATA_PHY_WR_DQS_SLAVE_RATIO 0x000 | 0x000 | 0x000 | 0x000
DATA_PHY_WR_DATA_SLAVE_RATIO 0x000 | 0x000 | 0x000 | 0x000
***************************************************************
rd_dqs_range = 0
fifo_we_range = 0
wr_dqs_range = 0
wr_data_range = 0
Optimal values have been found!!

===== END OF TEST =====
I also use the GEL scripts ,the test of DDR_DataTransferCheck() and EDMA() to test the DDR both of which is failed The result is also in a log file attached.
Kindly help in configuring the DDR.
Thanks in advance,
