[U-Boot-Users] bootm and script images
by Matthias Fuchs 16 Sep '05

16 Sep '05

Hi, I am wondering if there is a special reason why bootm currently cannot handle script images. Does anything speak against bootm calling autoscript() for AU_SCRIPT marked images? Matthias

[U-Boot-Users] Difference between ppc-linux-gcc and ppc_82xx-gcc?
by Sam Song 16 Sep '05

16 Sep '05

Hi all, I encountered a compiling problem on fw_printenv tool in u-boot-1.1.3 tools directory. When setting CROSS_COMPILE=ppc-linux-, there would be a problem but not for CROSS_COMPILE=ppc_82xx-. Well, the funny thing is that both settings work fine to compile a MPC8272ADS image if I disable fw_printenv compilinig in tools/Makefile. ...... thfw_env_main.c:55: (Each undeclared identifier is reported only once fw_env_main.c:55: for each function it appears in.) fw_env_main.c:59: warning: implicit declaration of function `strcmp' fw_env_main.c:63: `EXIT_SUCCESS' undeclared (first use in this function) fw_env_main.c:68: `EXIT_FAILURE' undeclared (first use in this function) fw_env_main.c:73: warning: implicit declaration of function `fprintf' fw_env_main.c:73: `stderr' undeclared (first use in this function) make[2]: *** [fw_printenv] Error 1 make[2]: Leaving directory `/home/sam/work-folder/u-boot-1.1.3/tools/env' make[1]: *** [subdirs] Error 1 make[1]: Leaving directory `/home/sam/work-folder/u-boot-1.1.3/tools' make: *** [tools] Error 2 [root@sam u-boot-1.1.3] Did anyone encounter this case? How it could be? Hope some people take care this difference in the same situation. I tried ELDK3.0 and ELDK3.1.1 and both failed like this. A lesson learned? !

[U-Boot-Users] [PATCH] wrong lcd splashscreen colors (pxa)
by Francesco Mandracci 16 Sep '05

16 Sep '05

Hello world :) it seems that the computation of colors in common/lcd.c:lcd_display_bitmap() is wrong for green and blue components. I checked on version 1.1.3 and on cvs.sf.net. I'm working on a PXA270 but this seems general (as far as I understand). The error is not evident until you use full colors (i.e. if color RGB components/bytes are either 0x00 of 0xff). ------------------------------------------------------ bmp_color_table_entry_t cte = bmp->color_table[i]; ushort colreg = ( ((cte.red) << 8) & 0xf800) | - ( ((cte.green) << 4) & 0x07e0) | - ( (cte.blue) & 0x001f) ; + ( ((cte.green) << 3) & 0x07e0) | + ( ((cte.blue) >> 3) & 0x001f) ; #ifdef CFG_INVERT_COLORS *cmap = 0xffff - colreg; #else *cmap = colreg; #endif ------------------------------------------------------ Hoping this helps. Ciao Francesco Mandracci PS Thank you all for the great job: it's the first time I get to a bootloader prompt (on a new hardware) after only about 6 hours of work.

They must match your architecture, your board's memory map and your kernel configuration. BTW: allthis has been discussed many times before on this list; it would have been a good idea to search a bit in the archives. > What is the justification of saying "This is bound to fail on ARM" for > load address =0 and entry point =0? ARM has usually ROM at address 0; you will not be able to copy your kernel to this address; the following jump to this address provokes undefined behaviour.

[U-Boot-Users] Problem to boot with Multi-File Image
by batsayan.das＠tcs.com 16 Sep '05

Hello, I am trying to boot the OMAP5912 board from u-boot prompt, with a multi file image. I copied the image to RAM at address 10000000, and and execute " bootm 10000000". The system hangs. Even the hard reset does not give the u-boot. FLASH size is 32M RAM size is 32M I was able to boot with the same kernel image at FLASH and the ramdisk mounted as NSF. I used the following command to create the multi file image "mkimage -A arm -O Linux -T multi -C gzip -n 'Ramdisk Image' -d omap/vmlinux.gz:ramdisk.img.gz linux.img" and set "bootargs=rw" before running " bootm 10000000". The following o/p I got Pls help. ***********************LOG*********************************** OMAP5912 OSK # bootm 10000000 ## Booting image at 10000000 ...

[U-Boot-Users] POST on new architecture?
by Robin Getz 15 Sep '05

15 Sep '05

We were looking at adding POST support to our platform, and was digging into POST/ether.c (which seems to be specific for Serial Communication Controllers (SCC). I was wondering if it would be better to add the loopback control into the specific ethernet driver? in ./drivers? Or what way would you prefer to add testing of other architectures ethernet / uart / usb peripherals? Thanks -Robin

Has anyone had any requests for wget? A few users have told me it is easier to set up a http server than a tftp server (firewalls and such). Thanks. -Robin

Re: [U-Boot-Users] Re: "go addr" Question...
by Robin Getz 14 Sep '05

Just an update - We found out what the issue was - the application in question assumed caches were off when it started, and re-initialized things without flushing things, which the hardware didn't like. Since this doesn't seem like a generic U-Boot issue - we are just making sure that when applications are started - they assume cache can be on or off, and set things appropriately. Thanks for the help.
