[U-Boot] On simple standalone applications
by Alessio Sangalli 31 Aug '08

Hi, I have problems in writing an application for U-boot. I do not need U-boot functions (for now), I just have to write some registers and then fill some memory with a value. The HW will read that memory region for its usage. I work on a ARM9 board whose RAM is mapped from 0x000000 to 0x04000000 (64MB). I have been privided U-boot 1.2.0 for this board. First problem: I can compile U-boot with ELDK 4.1 but if I enter the "examples" directory and issue a make: uboot-1.2.0/examples# make Makefile:64: /config.mk: No such file or directory Makefile:174: /rules.mk: No such file or directory make: *** No rule to make target `/rules.mk'. Stop. So I am unable to compile the examples. What should I do? By the way, I noticed that: uboot-1.2.0/doc/README.standalone [...] 4. The default load and start addresses of the applications are as follows: [...] ARM 0x0c100000 0x0c100000 I do not have RAM at that location! Shall I modify the Makefile for this? Anyway, I wrote a small program that does what I described above: int test02() { volatile int* r; int i; *(volatile int*)(0xc0001200) = 0x00000000; *(volatile int*)(0xc0001220) = 0x0257031f; *(volatile int*)(0xc0001224) = 0x00162028; r = (int*)0x00800000; for(i=0; i<0x100; i++) *r = 0x00000000; return 0; } I know, it's ugly and I could do everything with a bunch of u-boot's 'mw' commands, but this is only supposed to be a quick test. I have compiled it with: arm-gcc -c test02.c && arm-objcopy -O binary test02.o test02.bin && cp test02.bin /tftpboot/ and then, on the target's u-boot prompt: > tftp 1000000 test02.bin TFTP from server 192.168.1.77; our IP address is 192.168.1.10 Filename 'test02.bin'. Load address: 0x1000000 Loading: # done Bytes transferred = 252 (fc hex) > go 1000000 ## Starting application at 0x01000000 ... The first part of the program, the register writing, works, I get my hardware enabled. But the 'for' loop is not well 'relocated' and points to undefined code in random memory areas, and the CPU gets stuck. Any advice? Thank you Alessio

I'd invert the sense of the > ifdef, and have it be something like CFG_BROKEN_ECC_COMPATIBILITY. The concern with this is people that use their own custom config files will need to add this #define when they upgrade. How about just changing the name to CFG_NEW_NAND_ECC_FORMAT then? > If the old way of doing small page ECC was valid, should we preserve > that (and change Linux back)? That's a little controversial. Basically, the old OOB layout didn't match any other layout used (except by the MV kernel), the actual ECC layout meant that the method for correction was overly complex (with 170 non-obvious lines of code), and allegedly broken: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/32035 The new code is about 30 lines, really simple, and I can even prove it's correctness (which I couldn't even begin to with the old code). Troy (cc'd) I believe was the original author. It could probably do with some comments though to make it dead obvious to the casual observer what's going on. I'll add them in. > We should probably default to doing it the right way, not the > broken-but-compatible way for large pages, though. It depends if you put backwards compatibility over reliability though. Many davinci users are still running the MontaVista-supplied 2.6.10 kernel which has the same broken ECC code and I've heard no word from MV on fixing it yet (and they're probably struggling to deal with the same backwards compatibility issue). How about this solution: in davinci/nand.c, we add something like this: #if defined(CFG_NAND_LARGEPAGE) && !defined(CFG_LINUX_COMPATIBLE_ECC) /* Comment this #error out only if you really really have to. */ #error "You are using old ECC code that is broken on large page devices. See doc/README.davinci" #endif This forces the user to make a choice - they'll probably curse while they're doing it, but they can't plead ignorance when they find their large page NAND isn't detecting ECC errors. > Perhaps we could use some currently unused OOB byte as a marker > for new/old ECC layout? Could do, but any filesystems which use the OOB bytes might step on these. It also complicates the code even moreso and creates a lot more scenarios to test and that could go wrong. I really do believe it should be a clean switch from one format to the other, for both small and large page NAND, with no run-time backwards compatibility. But that's just my POV. Cheers, Bernard.

[U-Boot] [PATCH] ppc44x: Unification of virtex5 pp440 boards v3
by Ricardo Ribalda Delgado 30 Aug '08

30 Aug '08

This patch provides an unificated way of handling xilinx v5 ppc440 boards. It unificates 3 different things: 1) Source code A new board called ppc440-generic has been created. This board includes a generic tlb initialization (Maps the whole memory into virtual) and defines board_pre_init, checkboard, initdram and get_sys_info weakly, so, they can be replaced by specific functions. If a new board needs to redefine any of the previous functions (specific initialization) it can create a new directory with the specific initializations needed. (see the example ml507 board). 2) Configuration file Common configurations are located under configs/xilinx-ppc440.h, this header file interpretes the xparameters file generated by EDK and configurates u-boot in correspondence. Example: if there is a Temac, allows CMD_CONFIG_NET Specific configuration are located under specific configuration file. (see the example ml507 board) 3) Makefile Some work has been done in order to not duplicate work in the Main Makefile. Please see the attached code. In order to support new boards they can be implemented in the next way: a) Simple Generic Board (90% of the time) Using EDK generates a new xparameters.h file, replace ppc440-generic/xparameters.h and run make xilinx-ppc440-generic_config && make b) Simple Boards with special u-boot parameters (9 % of the time) Create a new file under configs for it (use ml507.h as example) and change your paramaters. Create a new Makefile paragraph and compile c) Complex boards (1% of the time) Create a new folder for the board, like the ml507 Finally, it adds support for the Avnet FX30T Evaluation board, following the new generic structure: Cheap board by Avnet for evaluating the Virtex5 FX technology. This patch adds support for: - UartLite - 16MB Flash - 64MB RAM Prior using U-boot in this board, read carefully the ERRATA by Avnet to solve some memory initialization issues. v2 diff: - Code Styling (Michal Simek) -

[U-Boot] [PATCH] mpc83xx: set gpio level before direction
by Peter Korsgaard 29 Aug '08

29 Aug '08

Set gpio level register before direction register to inhibit glitches on high level output pins. Dir and data gets cleared at powerup, so high level output lines see a short low pulse between setting the direction and level registers. Issue was seen on a new board with the nReset line of the NOR flash connected to a GPIO. Setting the direction register puts the NOR flash in reset so the next instruction to set the level cannot get executed.
