yes, a change to the build system broke sandbox. you'll need the recent patch to fix things up: [PATCH V3] sandbox: Add improved RAM simulation -mike

Dear Simon,

with current top of tree (v2011.09-690-gfec79ac) I see this (on a i686 host):

-> ./MAKEALL sandbox Configuring for sandbox board... cmd_nvedit.c: In function ‘do_env_export’: cmd_nvedit.c:748:3: warning: format ‘%zX’ expects argument of type ‘size_t’, but argument 3 has type ‘long unsigned int’ [-Wformat] cmd_nvedit.c:774:2: warning: format ‘%zX’ expects argument of type ‘size_t’, but argument 3 has type ‘long unsigned int’ [-Wformat] cmd_nvedit.c: In function ‘do_env_import’: cmd_nvedit.c:865:3: warning: format ‘%zd’ expects argument of type ‘signed size_t’, but argument 2 has type ‘size_t’ [-Wformat] cmd_nvedit.c:865:3: warning: format ‘%zX’ expects argument of type ‘size_t’, but argument 3 has type ‘long unsigned int’ [-Wformat] hashtable.c: In function ‘hexport_r’: hashtable.c:494:2: warning: format ‘%d’ expects argument of type ‘int’, but argument 5 has type ‘size_t’ [-Wformat] hashtable.c:542:4: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t’ [-Wformat] hashtable.c:542:4: warning: format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘long unsigned int’ [-Wformat] hashtable.c: In function ‘himport_r’: hashtable.c:643:3: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t’ [-Wformat]   text    data     bss     dec     hex filename  101737    3004   26128  130869   1ff35 ./u-boot

I have sent up a series which aims to fix a few of these warnings. They don't come up on MAKEALL for me except for microblaze:

fat.c: In function 'do_fat_read': fat.c:876: warning: format '%d' expects type 'int', but argument 4 has type 'long unsigned int' cmd_nvedit.c: In function 'do_env_export': cmd_nvedit.c:748: warning: format '%zX' expects type 'size_t', but argument 3 has type 'unsigned int' cmd_nvedit.c:774: warning: format '%zX' expects type 'size_t', but argument 3 has type 'unsigned int' cmd_nvedit.c: In function 'do_env_import': cmd_nvedit.c:865: warning: format '%zu' expects type 'size_t', but argument 2 has type 'unsigned int' cmd_nvedit.c:865: warning: format '%zX' expects type 'size_t', but argument 3 has type 'unsigned int' cmd_mtdparts.c: In function 'device_parse': cmd_mtdparts.c:878: warning: field precision should have type 'int', but argument 2 has type 'long unsigned int' hashtable.c: In function 'hexport_r': hashtable.c:494: warning: format '%zu' expects type 'size_t', but argument 5 has type 'unsigned int' hashtable.c:542: warning: format '%zu' expects type 'size_t', but argument 2 has type 'unsigned int' hashtable.c:542: warning: format '%zu' expects type 'size_t', but argument 3 has type 'unsigned int' hashtable.c: In function 'himport_r': hashtable.c:643: warning: format '%zu' expects type 'size_t', but argument 2 has type 'unsigned int'

I can't easily see how to remove the hashtable / cmd_nvedit ones in this case.
