by Stage Iup - Fabrice & Frederic 25 Aug '05

25 Aug '05

Hi i'm actually using U-Boot 1.1.2 on an AT91RM9200 based board and if changed few files to use an LXT971A Phy component instead of using the Phy Davicom component. So i would like to create a .patch file to put all my modifications on U-Boot 1.1.3. Can someone indicates me how can i do it? -- With regards Frédéric Kwiatkowski -- IFOTEC Tél : 04 76 67 53 53

[U-Boot-Users] Software watchdog on mpc8247
by Mike Rapoport 25 Aug '05

25 Aug '05

Hello, I have a custom board with mpc8247 processor. I'd like to use it's internal watchdog capability in u-boot (and linux). I've tried to use the folliwing defines in my board config file (include/configs/my_board.h): #define CONFIG_WATCHDOG 1 #if defined(CONFIG_WATCHDOG) #define CFG_SYPCR (SYPCR_SWTC|SYPCR_BMT|SYPCR_PBME|SYPCR_LBME|\ SYPCR_SWRI|SYPCR_SWP|SYPCR_SWE) #else #define CFG_SYPCR (SYPCR_SWTC|SYPCR_BMT|SYPCR_PBME|SYPCR_LBME|\ SYPCR_SWRI|SYPCR_SWP) #endif /* CONFIG_WATCHDOG */ but the board does not boot when the watchdog is enabled. I use u-boot 1.1.3 release. -- Sincerely yours, Mike Rapoport

[U-Boot-Users] RFC: U-Boot Environment support in SystemAce Compact FLASH
by Keith J Outwater 23 Aug '05

23 Aug '05

Hello all - I have completed the initial port of U-Boot to a custom PPC405/VirtexII Pro FPGA board and I am starting to look at ways to store the U-Boot environment in the CF card used for FPGA configuration by the Xilinx SystemAce. As it stands now, there is DOS FAT read support in U-Boot but no write support, so that would have to be added if the environment was to be stored as a DOS file on the CF card. Another option might be to partition the CF card so as to leave a few sectors unused and use low-level sector read/write routines to store the environment directly to the CF card. This solution seems straightforward, but seems somehow inelegant. I am leaning toward the approach of adding DOS FAT write support and adjusting the initial U-Boot environment to provide sufficient stack space to run the DOS filesystem code during initial boot. Does this seem reasonable? Does anyone know where the original DOS filesystem code came from? Keith

RE: [U-Boot-Users] [PATCH] cfi_flash.c patches
by Woodruff, Richard 23 Aug '05

23 Aug '05

Tolunay, Several Intel chips do provide hardware level protection locks which get cleared at reset. It is useful to use this hardware feature at boot to help protect flash sectors from upper level code during normal operation. The u-boot software lock is nice, but doesn't extend beyond u-boot code while the hardware lock does. The difference in behavior between chips is the issue here. Perhaps it is better to add another compile time flag which allows the hardware features to be used on such chips. Your point is one _hardware_ features behavior should be valued over another's. Having them both via flags is probably the way to go.

[U-Boot-Users] Using "cu" for tranferring files

I did try to use "cu" for tranferring the files. But i can see the monitor command prompt and not enter any input. This problem is related to the flow control, i reckon, and so i try to figure out how do i set it. I have used the settings as mentioned in the DULG manual for setting up "cu". hardflow is set to false. but still i cannot input any values. Is there any other way of setting the hardware and software flow control to none. How do i get this working.

[U-Boot-Users] regarding uboot
by prabha.j＠tcs.com 23 Aug '05

Sir, My name is prabha. I have some questions regarding the uboot. I hope u will help me in this regard. 1.Actually i have a target as intel board with P4 machine and having 830 as intel chip set. I searched whether uboot supports this architecture. I came to know that uboot supports very few intel boards. Now the question is how to bring up this board using uboot and how to get the toolchain for this board. Will uboot supports this architecture or not. 2. I am using p4 as my host m/c and untarred uboot1.1.3 and when i gave make sc520_cdp_config it gives Configuring for sc520_cdp board... and after this if i give make it gives error as make 'make[1]: Entering directory `/root/praba/u-boot-1.1.3/tools' make[1]: `.depend' is up to date. make[1]: Leaving directory `/root/praba/u-boot-1.1.3/tools' make[1]: Entering directory `/root/praba/u-boot-1.1.3/examples' make[1]: `.depend' is up to date. make[1]: Leaving directory `/root/praba/u-boot-1.1.3/examples' make[1]: Entering directory `/root/praba/u-boot-1.1.3/post' make[1]: `.depend' is up to date. make[1]: Leaving directory `/root/praba/u-boot-1.1.3/post' make[1]: Entering directory `/root/praba/u-boot-1.1.3/post/cpu' make[1]: `.depend' is up to date. make[1]: Leaving directory `/root/praba/u-boot-1.1.3/post/cpu' make -C tools all make[1]: Entering directory `/root/praba/u-boot-1.1.3/tools' gcc -g -Wall -pedantic -idirafter ../include -DTEXT_BASE=0x387c0000 -DUSE_HOSTCC -O -c envcrc.c gcc -g -idirafter ../include -DTEXT_BASE=0x387c0000 -DUSE_HOSTCC -c environment.c gcc -Wall -pedantic -idirafter ../include -DTEXT_BASE=0x387c0000 -DUSE_HOSTCC -O -o envcrc envcrc.o crc32.o environment.o make[1]: Leaving directory `/root/praba/u-boot-1.1.3/tools' make -C examples all make[1]: Entering directory `/root/praba/u-boot-1.1.3/examples' gcc -g -Os -D__KERNEL__ -DTEXT_BASE=0x387c0000 -I/root/praba/u-boot-1.1.3/include -fno-builtin -ffreestanding -nostdinc -isystem /usr/lib/gcc/i386-redhat-linux/3.4.2/include -pipe -DCONFIG_I386 -D__I386__ -march=i386 -Werror -Wall -Wstrict-prototypes -c -o 82559_eeprom.o 82559_eeprom.c 82559_eeprom.c: In function `memcpy': 82559_eeprom.c:57: warning: use of cast expressions as lvalues is deprecated 82559_eeprom.c:57: warning: use of cast expressions as lvalues is deprecated make[1]: *** [82559_eeprom.o] Error 1 make[1]: Leaving directory `/root/praba/u-boot-1.1.3/examples' make: *** [examples] Error 2 Now the question is that should i have to build toolchain for this or not.

[U-Boot-Users] Boot x86 target from flash, with the image and file system on the x86 host.
by batsayan.das＠tcs.com 23 Aug '05

23 Aug '05

I am exploring the nfs boot of Fedora 3 for x86 platform. I have two x86 m/c. One(host) is loaded with FC3 . The other (target) has only blank IDE flash dive. My plan is : 1.Prepare kernel image "at the host for the target". (Pls note that host and target both are x86. ) 2.Prepare file system "at the host for the target". 3.NFS mount the kernel image and the file system at host. 4.Connect the flash to the host burn the flash with kernel image 5.Connect the flash to the target and power on the target. 6.The target will, download the image from the host; mounts file sys and boots. The flash should have some boot loader like u-boot along with the kernel image. I am not sure whether bootloader + kernel image can be mixed together and put into the flash. The other solution may be to put only the bootloader onto the flash. When the target is powered on with the IDE flash, the (boot loader+ kernel image) OR (the boot loader) should start up the x86 platform. Pls note that the kernel image, file system etc are kept on the host system by nfs mount. Any pointer to the above will be of great help.

[U-Boot-Users] debugging U-boot with GDB on a Au1550

I have U-boot running on a Au1550 platform. I have verified that re-location to RAM works but the system is crashing somewhere in board_init_r. I would like to debug this with GDB and a BDI2000, but am running into a few issues. U-boot for this platform is linked to 0xbfc00000 (the ROM reset vector). This is not what I am used to as most ARM platforms are linked to the RAM location. After U-boot is relocated to RAM, how do I tell GDB what the new link address is (0x80fdc000 in this case)?

[U-Boot-Users] U-Boot interpreter syntax change?
by Keith J Outwater 22 Aug '05

22 Aug '05

Hello - I was recently porting some old U-Boot scripts to my new board and I was having a problem with the kernel command line. Instead of getting substitutions for things like $(ipaddr), I was seeing, literally, $(ipaddr) in the kernel command line as reported by the kernel. I also saw a similar problem with the U-Boot tftpboot command. This: Ant2> setenv load_kernel tftp $(loadaddr) $(kernel_image); Ant2> run load_kernel Gives this output from U-Boot: Ant2> run load_kernel TFTP from server 192.168.0.100; our IP address is 192.168.0.10 Filename '$(kernel_image)'. While this: Ant2> setenv load_kernel tftp $loadaddr $kernel_image Ant2> run load_kernel Gives this: Ant2> run load_kernel TFTP from server 192.168.0.100; our IP address is 192.168.0.10 Filename 'kernel.uImage'. Which works. I checked the DULG, and the guide indicates that the first form shown above is correct. Have things changed or do I have something misconfigured? Any ideas? Thanks, Keith

[U-Boot-Users] test variable existence in hush
by Andreas Engel 22 Aug '05

22 Aug '05

Hi, can anyone confirm that this is a bug in the hush shell: both test -n "$foo" && echo yes and test -z "$foo" && echo yes result in nothing echoed if foo is not defined. If, on the other hand, foo is defined to a string containing blanks, both commands will echo yes. Is there another way to check the existence of a variable? Regards, Andreas Engel
