Hi Wolfgang, The link says about the initialization of the SDRAM; Does it applicable in our case, where we have SRAM on our board. Does the initialization means just clearing the memory in case of SRAM ? We tried clearing the memory before the operation which doesnt work too. We are creating a TLB of 16MB for the SRAM which is not cachable .
