Does it mean I have to CFI_MTD ot common CFI_DRIVER will works?
I was asking that do I also need to add below settings in my board config file.
/*
- Dynamic MTD partition support
*/ #define CONFIG_CMD_MTDPARTS #define CONFIG_MTD_DEVICE /* needed for mtdparts commands */ #define CONFIG_FLASH_CFI_MTD #define MTDIDS_DEFAULT "nor0=fc000000.flash"
No, you don't need those defines for "normal" FLASH access in U-Boot.
And you need to configure your access timing for the chip select to the NOR Chip correctly of course.
In which source file I can see present access timings for the chip select. 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.
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.
Cheers, Stefan
