Hi,

 

Did you check whether ddr3 read of your custom IP working fine or not? Sometime this behavior is due to DDR3 read error.

 

Rgds,

@sreelaullas actually  my custom ip is a slave ip.Microblaze is the master that has acess to DDr3 memory as well as the slave ip.

microblaze can read ddr3 memory and write to it.also microblaze can read and write into the custom slave ip that i created.The problem comes when i am using one microblaze and two slaves(mig and custom ip in the same design.
