This patch re-formats the s3c24x0 header files in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct, from a comment by Wolfgang on 03/06/2009 - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones, from a comment by Scott on 22/06/2009 - make sure registers are accessed using the proper accessor functions, from a comment by Wolfgang on 03/06/2009 - run checkpatch.pl and fix any error reports Signed-off-by: Kevin Morfitt <kevin.morfitt(a)fearnside-systems.co.uk> --- include/s3c2400.h | 493 ++++----------------------------------------

[U-Boot] Patch to boot over USB cable on OMAP3EVM
by Brian Silverman 08 Jul '09

08 Jul '09

I have created a patch for the OMAP3EVM u-boot to create an image for download into OMAP internal RAM (64k). This allows a complete boot to Linux over USB only, without any RS-232 serial cables. The difference between this and Nishanth Menon's procedures (found here: http://nishanthmenon.blogspot.com/2008/12/towards-creating-beagleboard-n and.html) is simply that the RS232 serial port is not required. If anybody has any input into this, or finds this useful, please share... Here's an executive summary of the boot process: - Setup OMAP3EVM to boot via USB - Start Martin Mueller's omap3_usbload to download the u-boot.bin image - Run a kermit script to talk to the board over /dev/ttyACM0, and download uImage/ramdisk images. - bootm - Linux boots to the command line. Also note: this builds off of a u-boot USB dev branch, not mainline u-boot. The details: - Images: - omap3_usbload: - Download and build omap3_usbload (Nishanth Menon's pusb should work as well): http://groups.google.com/group/beagleboard/browse_thread/thread/2b9e9988 6bb7a747 - Note: requires the libusb package. - u-boot - Get Steve's Sakoman's u-boot usb dev branch: - See http://elinux.org/U-boot_musb_gadget_support - In short (from gitorious): git clone git://gitorious.org/u-boot-omap3/mainline.git cd mainline git checkout --track -b omap3-dev-usb origin/omap3-dev-usb - Current latest commit is commit 6c4dabfd6e32eed49624f773fc39140c4b1322b1 - Apply the attached patch (Note: I'm new to git, and I've just attached a "diff -urN" patch. With a little help, I'd be happy to upload a proper "git" patch). For example: - cd mainline - patch -p1 < ../u-boot-omap3evm-usb-boot.patch - Build u-boot: make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omap3_evm_config make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- - You now have a downloadable u-boot.bin. Copy it to u-boot2.bin to avoid confusion. I'll use that name in the script later. - Kermit - Download CKermit with your favorite package manager. - Also you'll need the attached kermrc script. It was created from: http://www.denx.de/wiki/DULG/SystemSetup, section 4.3, with the notable exception about send/recv buffers (see notes at end of this email). - uImage - You'll need the default OMAP3EVM Linux image, but you'll have to rebuild it and make one change: - Remove defines for the ethernet driver. If you include it, the driver will crash on boot because this u-boot does not initialize the Ethernet core. The applicable configs are: # CONFIG_MII is not set # CONFIG_SMSC911X_OMAP3EVM is not set - ramdisk: - For my example below, I convert the ramdisk to uboot format. To do this: mkimage -n 'uboot ext2 ramdisk rootfs' -A arm -O linux -T ramdisk -C gzip -d \ ~/OMAP35x_SDK_1.0.2/ramdisk-min.gz ramdisk.ext2.gz.uboot - OMAP3EVM Board setup: - The jumpers need to be set for USB boot. For my board, I've set it to boot USB boot first, MMC boot second, which is: SW4 (1-8): ON OFF OFF ON ON OFF OFF OFF - Connect the USB cable to your Linux host - Connect a serial cable to see the Linux console (not required, but recommened for first time at least). - On the host: - Given the attached scripts and the above built binaries, run: ./usbload - usbload/kermrc scripts currently have the image names embedded in them. They should all be in the current dir. - Output you should see on host: bri@bri-desktop:~/tmp/Beagle/omap3_usb/host$ ./usbload TI OMAP3 USB boot ROM tool, version 0.1 (c) 2008 Martin Mueller <martinmm(a)pfump.org> ....................... found device! download ok Loading Linux image... Done Loading Linux image. Loading RamDisk image... Done Loading RamDisk image. Booting Linux... Check serial console for more messages. In addition, you will see the kermit download manager in the terminal in full screen. - Notes: - The memory map on the target is: 0x40200000 Internal RAM start. Max top of stack 0x40201000 Top of stack, start of code/data/bss 0x4020F000 Reserved for ROM boot code. - The u-boot image created is VERY tight in memory. We have 60k to use, and the image is within 256 bytes of the max. Be aware of this if/when porting to the beagle board. Most of the changes in the patch were to reduce the code size. - kermit download over /dev/ttyACM0 will not work if the send/receive buffers are greater than 128 or so. They have been set to 128 in kermrc. - omap3_usbload must be run as root, as libusb seems to require it. The usbload script uses sudo to do this. Hope this is useful to someone. If I've missed anything, just ask... Thanks for all the community support! ---- Brian Silverman Principal Engineer iVeia ---- Brian Silverman Principal Engineer iVeia

[U-Boot] [RFC][PATCH] Update malloc to dlmalloc version 2.8.4
by Kumar Gala 08 Jul '09

08 Jul '09

Signed-off-by: Kumar Gala <galak(a)kernel.crashing.org> --- This is an attempt at using dlmalloc v2.8.4. Its a work in progress, but wanted to post to see what peoples feelings are on updating. This version resolves all the various warnings we see w/gcc4.4 and the older version of dlmalloc however the trade of is the code size has increased. I still need to see if we need to hand relocate the global structs or not. This diff is just of malloc.h to see how things are cfg, and of dmalloc.src vs dmalloc.c to see the changes to it. - k diff --git a/include/malloc.h b/include/malloc.h index 47154b0..2af6c8a 100644 --- a/include/malloc.h +++ b/include/malloc.h @@ -1,942 +1,784 @@ -/* - A version of malloc/free/realloc written by Doug Lea and released to the - public domain.

This - seems to suffice for all current machines and C compilers. - - Assumed pointer representation: 4 or 8 bytes - Code for 8-byte pointers is untested by me but has worked - reliably by Wolfram Gloger, who contributed most of the - changes supporting this. - - Assumed size_t representation: 4 or 8 bytes - Note that size_t is allowed to be 4 bytes even if pointers are 8. - - Minimum overhead per allocated chunk: 4 or 8 bytes - Each malloced chunk has a hidden overhead of 4 bytes holding size - and status information. - - Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead) - 8-byte ptrs: 24/32 bytes (including, 4/8 overhead) - - When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte - ptrs but 4 byte size) or 24 (for 8/8) additional bytes are - needed; 4 (8) for a trailing size field - and 8 (16) bytes for free list pointers. Thus, the minimum - allocatable size is 16/24/32 bytes. - - Even a request for zero bytes (i.e., malloc(0)) returns a - pointer to something of the minimum allocatable size. - - Maximum allocated size: 4-byte size_t: 2^31 - 8 bytes - 8-byte size_t: 2^63 - 16 bytes - - It is assumed that (possibly signed) size_t bit values suffice to - represent chunk sizes. `Possibly signed' is due to the fact - that `size_t' may be defined on a system as either a signed or - an unsigned type. To be conservative, values that would appear - as negative numbers are avoided. - Requests for sizes with a negative sign bit when the request - size is treaded as a long will return null. - - Maximum overhead wastage per allocated chunk: normally 15 bytes - - Alignnment demands, plus the minimum allocatable size restriction - make the normal worst-case wastage 15 bytes (i.e., up to 15 - more bytes will be allocated than were requested in malloc), with - two exceptions: - 1. Because requests for zero bytes allocate non-zero space, - the worst case wastage for a request of zero bytes is 24 bytes. - 2. For requests >= mmap_threshold that are serviced via - mmap(), the worst case wastage is 8 bytes plus the remainder - from a system page (the minimal mmap unit); typically 4096 bytes. - -* Limitations - - Here are some features that are NOT currently supported - - * No user-definable hooks for callbacks and the like. - * No automated mechanism for fully checking that all accesses - to malloced memory stay within their bounds. - * No support for compaction. - -* Synopsis of compile-time options: - - People have reported using previous versions of this malloc on all - versions of Unix, sometimes by tweaking some of the defines - below. It has been tested most extensively on Solaris and - Linux. It is also reported to work on WIN32 platforms. - People have also reported adapting this malloc for use in - stand-alone embedded systems. - - The implementation is in straight, hand-tuned ANSI C.

Adds fairly extensive assertion-based - checking to help track down memory errors, but noticeably slows down - execution. - REALLOC_ZERO_BYTES_FREES (default: NOT defined) - Define this if you think that realloc(p, 0) should be equivalent - to free(p). Otherwise, since malloc returns a unique pointer for - malloc(0), so does realloc(p, 0). - HAVE_MEMCPY (default: defined) - Define if you are not otherwise using ANSI STD C, but still - have memcpy and memset in your C library and want to use them. - Otherwise, simple internal versions are supplied. - USE_MEMCPY (default: 1 if HAVE_MEMCPY is defined, 0 otherwise) - Define as 1 if you want the C library versions of memset and - memcpy called in realloc and calloc (otherwise macro versions are used). - At least on some platforms, the simple macro versions usually - outperform libc versions. - HAVE_MMAP (default: defined as 1) - Define to non-zero to optionally make malloc() use mmap() to - allocate very large blocks. - HAVE_MREMAP (default: defined as 0 unless Linux libc set) - Define to non-zero to optionally make realloc() use mremap() to - reallocate very large blocks. - malloc_getpagesize (default: derived from system #includes) - Either a constant or routine call returning the system page size. - HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined) - Optionally define if you are on a system with a /usr/include/malloc.h - that declares struct mallinfo. It is not at all necessary to - define this even if you do, but will ensure consistency. - INTERNAL_SIZE_T (default: size_t) - Define to a 32-bit type (probably `unsigned int') if you are on a - 64-bit machine, yet do not want or need to allow malloc requests of - greater than 2^31 to be handled. This saves space, especially for - very small chunks. - INTERNAL_LINUX_C_LIB (default: NOT defined) - Defined only when compiled as part of Linux libc. - Also note that there is some odd internal name-mangling via defines - (for example, internally, `malloc' is named `mALLOc') needed - when compiling in this case. These look funny but don't otherwise - affect anything. - WIN32 (default: undefined) - Define this on MS win (95, nt) platforms to compile in sbrk emulation. - LACKS_UNISTD_H (default: undefined if not WIN32) - Define this if your system does not have a <unistd.h>. - LACKS_SYS_PARAM_H (default: undefined if not WIN32) - Define this if your system does not have a <sys/param.h>. - MORECORE (default: sbrk) - The name of the routine to call to obtain more memory from the system. - MORECORE_FAILURE (default: -1) - The value returned upon failure of MORECORE. - MORECORE_CLEARS (default 1) - True (1) if the routine mapped to MORECORE zeroes out memory (which - holds for sbrk). - DEFAULT_TRIM_THRESHOLD - DEFAULT_TOP_PAD - DEFAULT_MMAP_THRESHOLD - DEFAULT_MMAP_MAX - Default values of tunable parameters (described in detail below) - controlling interaction with host system routines (sbrk, mmap, etc). - These values may also be changed dynamically via mallopt(). The - preset defaults are those that give best performance for typical - programs/systems. - USE_DL_PREFIX (default: undefined) - Prefix all public routines with the string 'dl'.

[U-Boot] Can't get sprintf to work in standalone program
by Martin Hejnfelt 08 Jul '09

08 Jul '09

Hi, I'm trying to use the sprintf function in a C program written for U-boot. As far as I understand, to get the function I have to add it to the exports.h, _exports.h and exports.c file as per the README.Standalone file in /doc (the function is declared in common.h). Now if I do this, the program compiles fine, and all is dandy, until I actually start using the function. It generates garbage. printf and alike works fine, and the program runs like it should, except the places where sprintf is used, I get garbage (meaning some environment variables are looking pretty nasty since the result of the sprintf functions are used for these). When compiling I link to the examples/libstubs.a file and lib_generic/libgeneric.a where the code I'm using should be present. Can anyone give me a clue to what the problem could be or if I misunderstood the concept completely? I searched the lists and in my frustration I tried to use some code from an earlier post where some guy had problems with sprintf. Here Wolfgang Denk wrote a small piece of code that used the function, and this was what I then put in my own code, just to see if I could get *anything* working with sprintf. The code I used was this: ... unsigned char buf[128]; unsigned char a[6] = { 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, }; int i; ... printf ("Before: "); for (i=0; i<6; ++i) printf (" %02X",a[i]); putc ('\n'); sprintf (buf, "%02X:%02X:%02X:%02X:%02X:%02X", a[0], a[1], a[2], a[3], a[4], a[5]); printf ("After: "); for (i=0; i<6; ++i) printf (" %02X",a[i]); putc ('\n'); printf ("buf=\"%s\"\n", buf); ... When I do this, the line that defines the a[6] thing generates a compiler error stating an undefined reference to memcpy. Since this error is present every time I try to initialize a string (char*) or char array I'm guessing this might be the problem, but I'm not sure... The platform is ARM (AT91RM9200)... U-boot version is 2009.06. I'm new to standalone programming for U-boot so this might surely be the problem, so any help is appreciated :) Kind regards, Martin Hejnfelt
