[U-Boot-Users] Is this a bug? /rtc/date.c
by Robin Getz 10 Oct '04

10 Oct '04

For architectures/boards which use the to_tm function in /rtc/date.c (which is alot) Dates up to 19Jan2038 03:14:08 work fine, but dates after don't: BOOT> date 011903142038 Date: 2038-01-19 (Tuesday) Time: 3:14:01 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:03 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:04 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:06 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-14:-7 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-14:-3 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-13:-59 This is due to the file the function math, or definition, depending what/where you think the bug is. (or if you think it is a bug at all). void to_tm(int tim, struct rtc_time * tm) because tim is a signed int, dates past 19Jan2038 03:14:08 show up as 1970 with negative days/hours. (ie. the date of 01jan2039 shows up as 1970-01--24507 (Wednesday) Time: -5:-27:-15) Potential solutions: 1) fix math, so negative years show up as years : dates can be set from 1902 to 2038 : 102 years ago, to 34 years in the future). OR 2) change function to be defined as: void to_tm(unsigned int tim, struct rtc_time * tm) which allows things to work until 2106, with existing math. OR 3) leave it alone, by 2010 everyone will have moved to 64-bit time_t, and things will be OK. OR 4) error if someone tries to set the date past 19Jan2038 03:14:08 (this is what Suse 9.0 does). I never checked to see what happens if I let Linux roll over - I didn't feel like crashing my workstation for test purposes, however, then you still need to do #1 above. I will check it out on an embedded target tomorrow. Because this affects so many architectures/boards, I thought I would ask: a) Does anyone care? b) What is the preferred method to fix? (I tried option 2, because it is the most trivial, and it seems to work fine for me). Thoughts? Opinions? -Robin

[U-Boot-Users] Simple JTAG programming tools
by Ing.Gianfranco Morandi 10 Oct '04

10 Oct '04

Dear collegues, forgive me if this subject, is not properly addressed into this list, but I think that almost all of us have been working with Flash. I'm currently working on ixp425 and by searching on the net I found a source code named JflashMM. This code seems to work in conjuction with a .dat (or .txt) file which contains the board configuration (only for pxa250). Anybody has already use this program over the ixp425 development platform? If yes, may I have the configuration file which has been used for? Many thanks Gianfranco

Hello Thomas, I misused CONFIG_MENUKEY in my test program and found an error but not quite sure. Pls check it. BTW, CONFIG_MENUKEY and CONFIG_MENUCOMMAND is only used in the AmigaOneG3SE board, which you maintaine. I didn't see their info in README. Could you pls explain the usage or even better send a patch in README? Thanks a lot.

[U-Boot-Users] How to disable serial console completely?
by Sam Song 10 Oct '04

10 Oct '04

Hi, I'd like to mask serial console totally for system deployment. When I set the console output by '#define CONFIG_8xx_CONS_NONE 1' and made a LCD image, I got the following compiling errors. What should I do next to disable serial console completely? Yeah, README mentions it a little but not enough, I am afraid. I think there should be a switch in <board.h> to disable the serial console simply. Any idea? -Map u-boot.map -o u-boot cpu/mpc8xx/libmpc8xx.a(lcd.o): In function `lcd_putc': /home/BK/lite_dw_u-boot/cpu/mpc8xx/lcd.c:535: undefined reference to `serial_putc' cpu/mpc8xx/libmpc8xx.a(lcd.o): In function `lcd_puts': /home/BK/lite_dw_u-boot/cpu/mpc8xx/lcd.c:574: undefined reference to `serial_puts' lib_ppc/libppc.a(board.o): In function `mem_malloc_init': /home/BK/lite_dw_u-boot/lib_ppc/board.c:130: undefined reference to `serial_init' common/libcommon.a(cmd_load.o): In function `do_load_serial_bin': /home/BK/lite_dw_u-boot/common/cmd_load.c:470: undefined reference to `serial_setbrg' /home/BK/lite_dw_u-boot/common/cmd_load.c:498: undefined reference to `serial_setbrg' common/libcommon.a(cmd_nvedit.o): In function `_do_setenv': /home/BK/lite_dw_u-boot/common/cmd_nvedit.c:244: undefined reference to `serial_setbrg' common/libcommon.a(console.o): In function `serial_printf': /home/BK/lite_dw_u-boot/common/console.c:113: undefined reference to `serial_puts' common/libcommon.a(console.o): In function `getc': /home/BK/lite_dw_u-boot/common/console.c:174: undefined reference to `serial_getc' common/libcommon.a(console.o): In function `tstc': /home/BK/lite_dw_u-boot/common/console.c:187: undefined reference to `serial_tstc' common/libcommon.a(console.o): In function `putc': /home/BK/lite_dw_u-boot/common/console.c:204: undefined reference to `serial_putc' common/libcommon.a(console.o): In function `puts': /home/BK/lite_dw_u-boot/common/console.c:222: undefined reference to `serial_puts' common/libcommon.a(devices.o): In function `nulldev_putc': /home/BK/lite_dw_u-boot/common/devices.c:49: undefined reference to `serial_putc' /home/BK/lite_dw_u-boot/common/devices.c:49: undefined reference to `serial_puts' common/libcommon.a(devices.o): In function `nulldev_puts': /home/BK/lite_dw_u-boot/common/devices.c:52: undefined reference to `serial_getc' /home/BK/lite_dw_u-boot/common/devices.c:54: undefined reference to `serial_tstc' make: *** [u-boot] Error 1 [root@sgj lite_dw_u-boot]# Thanks in advance! ===== Best regards, Sam _________________________________________________________ Do You Yahoo!? 150万曲MP3疯狂搜，带您闯入音乐殿堂 http://music.yisou.com/ 美女明星应有尽有，搜遍美图、艳图和酷图 http://image.yisou.com 1G就是1000兆，雅虎电邮自助扩容！ http://cn.rd.yahoo.com/mail_cn/tag/1g/*http://cn.mail.yahoo.com/event/mail_…

It adds function calc_fbsize() that returns FB size, used in VIDEOLFB_TAG for passing fb info to linux kernel.
