I substitute my hardware with a newer SDRAM
so i've adapted EBUI registers but i'm not sure if these settings correct.
i use the ebiu_calc.htm received years ago from AD but if i calc my settings per hand they not
So using a BF537 DSP with 125MHz sysclock i use following values from datasheet
Bank specific Values
ext.bank size= 32MB
Column AddrWith = 9 bits
Minimum TRAS = 45ns
Minimum TRP = 20ns
Minimum TWR = 2cycles ???
refresh period 8192rows in 64ms
CAS latency at reset : 2cycles ??
so what are the correct values for EBIU_SDRRC / EBIU_SDBCTL / EBIU_SDGCTL
and what could happen if RRC reg is to big ???
is there a never version for the ebui_calc.htm available ?
