I suppose you mean the attached patch... the problem is that even if using that patch I still get: mipsel-linux-gcc -Wa,-gstabs -D__ASSEMBLY__ -g -Os -D__KERNEL__ -DTEXT_BASE=0xbfc00000 -I/home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/include -fno-builtin -ffreestanding -nostdinc -isystem /usr/local/mipsel/lib/gcc/mipsel-linux/3.4.3/include -pipe -DCONFIG_MIPS -D__MIPS__ -march=4kc -mtune=4kc -mabicalls -c -o cpu/mips/start.o /home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/cpu/mips/start.S /home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/cpu/mips/start.S: Assembler messages: /home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/cpu/mips/start.S:241: Error: can't resolve `_GLOBAL_OFFSET_TABLE_' {*UND* section} - `L11' {.text section} make: *** [cpu/mips/start.o] Error 1 Ciao, Rodolfo -- GNU/Linux Solutions e-mail: giometti at linux.it Linux Device Driver giometti at enneenne.com Embedded Systems home page: giometti.enneenne.com UNIX programming phone: +39 349 2432127 -------------- next part -------------- Index: ./cpu/mips/start.S =================================================================== RCS file: /home/develop/cvs_private/uboot-mips-exadron/cpu/mips/start.S,v retrieving revision 1.1.1.1 diff -u -r1.1.1.1 start.S --- a/./cpu/mips/start.S 16 Sep 2005 12:14:19 -0000 1.1.1.1 +++ b/./cpu/mips/start.S 27 Sep 2005 21:46:24 -0000 @@ -234,21 +234,34 @@ li t0, CONF_CM_UNCACHED mtc0 t0, CP0_CONFIG + /* Initialize GOT pointer. + */ + bal 1f + nop + .word _GLOBAL_OFFSET_TABLE_ - 1f + 4 +1: + move gp, ra + lw t1, 0(ra) + add gp, t1 + #ifdef CONFIG_INCA_IP /* Disable INCA-IP Watchdog. */ - bal disable_incaip_wdt + la t9, disable_incaip_wdt + jalr t9 nop #endif /* Initialize any external memory. */ - bal lowlevel_init + la t9, lowlevel_init + jalr t9 nop /* Initialize caches... */ - bal mips_cache_reset + la t9, mips_cache_reset + jalr t9 nop /* ... and enable them. @@ -260,21 +273,13 @@ /* Set up temporary stack. */ li a0, CFG_INIT_SP_OFFSET - bal mips_cache_lock + la t9, mips_cache_lock + jalr t9 nop li t0, CFG_SDRAM_BASE + CFG_INIT_SP_OFFSET la sp, 0(t0) - /* Initialize GOT pointer. - */ - bal 1f - nop - .word _GLOBAL_OFFSET_TABLE_ - 1f + 4 -1: - move gp, ra - lw t1, 0(ra) - add gp, t1 la t9, board_init_f j t9 nop -------------- next part -------------- A non-text attachment was scrubbed...
