I am using PPC440x5 Cpu core. How to check the chip-select flash is using? Earlier I have run the same code for M29W128GH and it works fine. But with S29GL512 it is not working. Now the difference is only in size and write/read timings. So I believe it should work in smooth manner. kilauea.h file is present in the U-boot. So does this board supports S29GL512P Nor flash chip?
