I don't think this can work:
cmd_nvedit.c:599:5: error: 'board_saveenv' aliased to undefined symbol
'saveenv'
cmd_nvedit.c:599:5: error: 'board_saveenv' aliased to undefined symbol
'saveenv'
make[1]: *** [/home/b04825/git/u-boot.0/1022/common/cmd_nvedit.o] Error 1
It looks like weak functions can't be in another source file?
If I change it to this, then it works:
static int __saveenv(void)
{
return saveenv();
}
int board_saveenv(void) __attribute__((weak, alias("__saveenv")));
int do_env_save(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])
{
printf("Saving Environment to %s...\n", env_name_spec);
return board_saveenv() ? 1 : 0;
}
