Dear Marcel,
Is there any example that boots from NOR ?
looking at the defines below, you are not really booting u-boot from NOR...
#define CONFIG_SKIP_LOWLEVEL_INIT
If you do that, you must have an initial boot code before u-boot. See below...
#define CONFIG_SKIP_RELOCATE_UBOOT
Not used anymore.
/* SDRAM */ #define CONFIG_NR_DRAM_BANKS 1 #define PHYS_SDRAM 0x70000000 #define PHYS_SDRAM_SIZE 0x08000000 /* 128 megs */
Those defines have had their names changed.
#define CONFIG_SYS_GBL_DATA_SIZE 128
This constant is wrong, use the auto-generated value.
/*
- Size of malloc() pool
*/ #define CONFIG_SYS_GBL_DATA_SIZE 128 /* 128 bytes for initial data */
This constant is wrong, use the auto-generated value.
Forgot to mention a few items :
I flash the NOR at address 0x10020000 TEXT_BASE is 0x10020000
That really implies you have another boot program running before u-boot. Proably AT91 bootstrap? Is it configured to jumo to 0x1002000, or does it copy u-boot to some SDRAM address and jumps there?
Have a look at the current implementation for top9000 in u-boot-arm/master and compare your files to it. Any differences to your code that are not board and/or SoC specific probably have to be fixed in your board code or you should be able to reason why it must be different for your board.
