Hi Frank,
What CPU are you using, and what chip-select is the flash using?
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?
Regards, Prakash

In which file I need to do these changes?
This is not really CFI driver related. It platforms/SoC specific. Which
CPU
are you using? Can you access the FLASH chip from your JTAG debugger?
I tried with the below setting but I am getting the same error as flash
not
found. So I am little bit concerned.
Prakash: As Stefan mentioned, this is probably not a CFI driver issue. Most probably a wrong/non memory controller setup. What CPU are you using, and what chip-select is the flash using?
First, you should be able to read, erase and write via the JTAG before you even think about U-Boot.
What are the error messages? Please post a log.
Please tell which boards supports the S29GL512P NOR flash, so that I can check for reference.
Check kilauea.h for example.
Stefan: Didn't know that. Should have known that a year ago ;-)
