In DDR_CTRL register in Control Module, there are SREF0 and SREF1 field.
When I read back DDR_CTRL, here it is
./mem_rdwr.out --rd 48140618
0x48140618: 0000000
So Both of SREF0 and SREF1 are 0. There are no specification about them.
I don't know if the value of 1 will enable self-refresh or disable self-refresh.
If the value of 1 will enable self-refresh, what should I do to set it in the right way?
Or just set it in ddr_pll_init_ti816x in uboot?
Thanks!
