hi

I.mx6 community

can any one help me in this regard

i have connected sram on eim bus and eim configured as half for NOR flash(64mb) and half for SRAM(32mb) and FPGA(32mb) for dualite

Register settings what i have done is

GPR1=0x4840001b

cs1 registers:(0x021b8018)

GCR1=0X00610081

GCR2=0X00001002

RCR1=0X1C022000

RCR2=0X0

WCR1=0X1C092480

WCR2=0X0

IOMUX (its default to lower half data bus)

 

so when i try to write data to sram through ds5 debugger 1 and 3 nibble is not changing only 0 and 2 modifying accordingly

what could be the problem is there any register to set

and NOR FLASH is also connected on lower half databus

 

thanks and regards

saida
