[U-Boot-Users] New Board Support
by Sangmoon Kim 09 Oct '03

09 Oct '03

Hi, The attached file is a patch for our board called debris. It has 350MHz MPC8245 processor, 128Mbyte SDRAM, 16Mbyte Flash, 1Mbyte EPROM, 4 10/100BASE-T Ethernet ports(82551ER), 4 UARTs(16C554), and CompactPCI Interface(21154) I think It can be a good example for those who want 64-bit(data bus width) flash interface. I also patched cpu/mpc824x/speed.c so that the speed of the board can be correctly reported. I would be appreciate if this patch is included in u-boot CVS tree. Regards, Sangmoon Kim

[U-Boot-Users] gcc print-libgcc-file-name
by Scott McNutt 09 Oct '03

09 Oct '03

The path to libgcc.a may be different based on gcc options. For example: $ powerpc-eabi-gcc -print-libgcc-file-name /usr/local/xtools/lib/gcc-lib/powerpc-eabi/3.2.1/libgcc.a $ powerpc-eabi-gcc -print-libgcc-file-name -msoft-float /usr/local/xtools/lib/gcc-lib/powerpc-eabi/3.2.1/nof/libgcc.a In some cases this can cause problems. In my case, the nios-elf-gcc path defaults to the 16-bit library (which results in a link-time failure). I need to include the -m32 flag to get the correct path to the 32-bit library. In the top-level Makefile, it seems the following would be preferred: PLATFORM_LIBS += -L $(shell dirname `$(CC) $(PLATFORM_CPPFLAGS) -print-libgcc-file-name`) -lgcc over something like: ifeq ($(CPU),nios) PLATFORM_LIBS += -L $(shell dirname `$(CC) -m32 -print-libgcc-file-name`) -lgcc else PLATFORM_LIBS += -L $(shell dirname `$(CC) -print-libgcc-file-name`) -lgcc endif The preferred works fine for the port I'm working on ... but I'm concerned about causing problems for other architectures/boards. Comments/suggestions welcome. --Scott

[U-Boot-Users] Extending bootm command.
by Steven Scholz 09 Oct '03

09 Oct '03

Hi there, from time to time it might be necessary to (decompress and) copy some data from flash to ram. The configuration data for an Altera ACEX 1K FPGA for instance is about 163KB. The gzipped file (for a quite complex design) is only 54kB. So instead of wasting three flash sectors one could store a gzipped and mkimage wrapped version of the data in flash. If calling mkimage with the type STANDALONE like [1] proposes one could then use "bootm" to decompress and copy these data to ram. In order to call "fpga load" afterwards one need the location and the resulting size of the data. That is why I suggest the following patch: * Patch by Steven Scholz, 29 Sep 2003: - A second parameter for bootm overwrites the load address for "Standalone Application" images. - bootm sets environment variable "filesize" to the resulting data lenght for "Standalone Application" images when autostart is set to "no". Then one could do something like if bootm $fpgadata $some_free_ram ; then fpga load 0 $some_free_ram $filesize ; fi Cheers, Steven [1] https://www.denx.de/twiki/bin/view/DULG/HowCanILoadAndUncompressACompressed… + diff -u ./common/cmd_bootm.c.orig ./common/cmd_bootm.c --- ./common/cmd_bootm.c.orig Fri Aug 29 22:58:07 2003 +++ ./common/cmd_bootm.c Mon Sep 29 10:18:56 2003 @@ -247,6 +247,10 @@ switch (hdr->ih_type) { case IH_TYPE_STANDALONE: name = "Standalone Application"; + /* A second argument overwrites the load address */ + if (argc > 2) { + hdr->ih_load = simple_strtoul(argv[2], NULL, 16); + } break; case IH_TYPE_KERNEL: name = "Kernel Image"; break; @@ -347,8 +351,12 @@ /* load (and uncompress), but don't start if "autostart" * is set to "no" */ - if (((s = getenv("autostart")) != NULL) && (strcmp(s,"no") == 0)) + if (((s = getenv("autostart")) != NULL) && (strcmp(s,"no") == 0)) { + char buf[32]; + sprintf(buf, "%lX", len); + setenv("filesize", buf); return 0; + } appl = (int (*)(cmd_tbl_t *, int, int, char *[]))ntohl(hdr->ih_ep); (*appl)(cmdtp, flag, argc-1, &argv[1]); return 0;

[U-Boot-Users] [PATCH] Calculate PLPRCR fields for MPC86x boards
by Pantelis Antoniou 09 Oct '03

09 Oct '03

Hi. The following patch adds a program in the tools directory which aids in the programming of the PLPRCR register for MPC86x based boards. That is given an input clock xin and a target clock gclk2 it will output (if possible) the values of the PCPRCR fields required.

[U-Boot-Users] u-boot support for IBM PPC405EP evaluation board
by Taian Su 08 Oct '03

08 Oct '03

I wonder if u-boot supports IBM PPC405EP evaluation board. I have checked u-boot-0.4.0 supporting list and found two boards with PPC405EP processor. They are the BUBINGA405EP and ASH405. I could not find any further detail spec about these borads, and can not verify if anyone of them is IBM PPC405EP evaluation board. Anyone can help would be highly appreciated. Thanks Taian
