Hi,you all,
When porting on my custom board,u-boot hanged at crc32.c:165 as following:
(gdb) s crc32 (crc=0, buf=0xfff80004 '' <repeats 200 times>..., len=524284) at crc32.c:162 /ppcboot/u-boot-1.0.0-scc3/lib_generic/crc32.c:162:7122:beg:0xfff0440c (gdb) s ^c
Program received signal SIGSTOP, Stopped (signal). 0x00001000 in ?? () (gdb)
For the sake of my special FLASH and board configuration(Hard reset interrupt prefix:0xfff and 4xE28F128J3A--4x8 bit mode),I let CFG_FLASH_BASE=0xFC000000 CFG_ENV_OFFSET=0x3F80000 CFG_ENV_SECT_SIZE=0x80000.
Meanwhile,I changed uInt len to uLong len for my big ENV sector in lib_generic/crc32.c code accordingly.But still hanged forever.Not to mention serial output.
153 uLong ZEXPORT crc32(crc, buf, len) 154 uLong crc; 155 const Bytef *buf; 156 uLong len; 157 { 158 #ifdef DYNAMIC_CRC_TABLE 159 if (crc_table_empty) 160 make_crc_table(); 161 #endif 162 crc = crc ^ 0xffffffffL; 163 while (len >= 8) 164 { 165 DO8(buf); 166 len -= 8; 167 } 168 if (len) do { 169 DO1(buf); 170 } while (--len); 171 return crc ^ 0xffffffffL; 172 }
What's wrong with that?By the way,is there anything special for having u-boot code at 0xFFF00000?Any help would be appreciated.I have trapped in porting my board nearly one month!
Best regards,
SAM
