DDR_DDR_SDRAM_MODE -how to find this value to be entered to the register base on dram chip
1.ESDMODE
2.SDMODE
how qcvs is generating this values ?
dear sir thanks for your reply
i have created an rcw file for 400mhz ddr3 with p2041 i have created a tcl file with qcvs for the 667 mhz ddr3 controller it is reading and writing fine
if i need to decrease the the timing to 667 mhz ddr3 by changing the code word and after flashing into the flash i am facing the error of protocol plugin error ,how to fix this ?
These values are really based on the SDRAM specification, you need to check the datasheet of the SDRAM you are using. For DDR3 memory SDMODE corresponds to Mode Register 0 (MR0) of the SDRAM, ESDMODE - to Mode Register 1 (MR1).
