I'm experiencing the following problem when building U-Boot with GCC 4.0.0 provided by ELDK 4.0 ARM. My struct bd_info looks like this:
typedef struct bd_info { int bi_baudrate; /* serial console baudrate */ unsigned long bi_ip_addr; /* IP Address */ unsigned char bi_enetaddr[6]; /* Ethernet adress */ struct environment_s *bi_env; ulong bi_arch_number; /* unique id for this board */ ulong bi_boot_params; /* where this board expects params */ #if defined(CONFIG_ZEFEER_DZA) || defined(CONFIG_ZEFEER_DZB) || \ defined(CONFIG_ZEFEER_DZG) || defined(CONFIG_ZEFEER_DZN) || defined(CONFIG_ZEFEER_DZQ) struct /* RAM configuration */ { ulong start; ulong size; } bi_dram[CONFIG_MAX_NR_DRAM_BANKS]; unsigned char nr_dram_bank; #else struct /* RAM configuration */ { ulong start; ulong size; } bi_dram[CONFIG_NR_DRAM_BANKS]; #endif #ifdef CONFIG_HAS_ETH1 /* second onboard ethernet port */ unsigned char bi_enet1addr[6]; #endif } bd_t;
The SDRAM detection algorithm finds how many SDRAM blocks are and how big they are. It fills the following fields accordingly.
struct /* RAM configuration */ { ulong start; ulong size; } bi_dram[CONFIG_MAX_NR_DRAM_BANKS]; unsigned char nr_dram_bank;
When start_armboot invokes simple_strtoul to fill the bi_enetaddr field, the bi_dram[1].start field gets overwritten with a spurious value. Is it actually a GCC-related problem? Any suggestions?
TIA, llandre
