MLK-11427 imx: mx7d: Update DDR script for mx7d sabresd board
Updated items:
memory set 0x307a0000 32 0x03040001 --> memory set 0x307a0000 32 0x01040001
This is just enable when LPDDR4 is enabled .
memory set 0x307a0064 32 0x0040005e --> memory set 0x307a0064 32 0x00400046
T_RFC_MIN this should be: RU(260ns*528Mhz)/2=69 (0x45)
memory set 0x307a00d0 32 0x00020001 --> memory set 0x307a00d0 32 0x00020083
PRE_CKE_X1024 be (500us*528Mhz/2)/1024 = 129, or 0x81
memory set 0x307a00d4 32 0x00010000 --> memory set 0x307a00d4 32 0x00690000
DRAM_RSTN_X1024 (200us*528Mhz)/1024=104, or 0x68
memory set 0x307a00e4 32 0x00090004 --> memory set 0x307a00e4 32 0x00100004
DEV_ZQINIT_X32 . Should be 16 clocks
memory set 0x307a0100 32 0x0908120a --> memory set 0x307a0100 32 0x09081109
T_FAW=(40ns*528Mhz)/2)=11
memory set 0x307a0104 32 0x0002020e --> memory set 0x307a0104 32 0x0007020d
tXPDLL=24ns*528Mhz=13clocks
File:
MX7D_EVK_DDR3_1GB_32bit.ds
Test result:
3 boards pass 2 days stress test.
