Being a long time u-boot developer, this is the first time I'm trying to get some fix for the open source code back to mainline. If anything wrong during the process, please be gentle :-) Thank you.

To test: ./u-boot -d dts/dt.bin , then issue: fdt addr 0x100, fdt print will then cause an segmentation fault. After this fix fdt print is functional. --- common/cmd_fdt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/common/cmd_fdt.c b/common/cmd_fdt.c index 5640ded..d5eebcb 100644 --- a/common/cmd_fdt.c +++ b/common/cmd_fdt.c @@ -123,7 +123,7 @@ static int do_fdt(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) if (control) gd->fdt_blob = blob; else - set_working_fdt_addr(blob); + set_working_fdt_addr((void *)addr); if (argc >= 2) { int len; -- 2.1.0 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
