[U-Boot] [PATCH] ARMV7: Fix build for non-OMAP3 boards
by Steve Sakoman 26 Oct '10

26 Oct '10

Commit c3d3a54 uses CONFIG_ARMV7 to determine whether to call the v7_flush_cache_all function. This breaks the build for all non-OMAP3 boards (like Panda and OMAP4430SDP) since there is only a v7_flush_cache_all implementation for OMAP3. This patch uses CONFIG_OMAP3XXX instead of CONFIG_ARMV7 so that only boards with a v7_flush_cache_all will make the call. Tested on Beagle, Overo, Panda, and OMAP4430SDP Signed-off-by: Steve Sakoman <steve.sakoman(a)linaro.org> --- diff --git a/arch/arm/lib/cache.c b/arch/arm/lib/cache.c index 5715168..30686fe 100644 --- a/arch/arm/lib/cache.c +++ b/arch/arm/lib/cache.c @@ -38,7 +38,7 @@ void flush_cache (unsigned long dummy1, unsigned long dummy2) /* disable write buffer as well (page 2-22) */ asm("mcr p15, 0, %0, c7, c10, 4" : : "r" (0)); #endif -#ifdef CONFIG_ARMV7 +#ifdef CONFIG_OMAP34XX void v7_flush_cache_all(void); v7_flush_cache_all();

[U-Boot] Not getting any prompt on hyper terminal
by Srinivas Ganji 26 Oct '10

26 Oct '10

Dear All, I am new to this U-Boot boot loader environment. We have a AMCC PPC 440EP processor board which is derived from AMCC Yosemite board. I meant, we have prepared (customised) our own board which is equivalent to AMCC Yosemite board. For this board, I build the U-Boot boot loader with the help of ELDK on Ubuntu x86 host system. However, I have modified the following file contents as per my board and processor attributes. file name located directory ------------- ------------------------ 1) yosemite.h u-boot/include/configs 2) board.c u-boot/arch/powerpc/lib 3) init.S and yosemite.c u-boot/board/amcc/yosemite 4) start.S u-boot/arch/powerpc/cpu/ppc4xx After above four file modifications, the u-boot.bin file is created and able to load into our board. However, we are NOT getting any prompt on the hyper terminal. When we debug the sources through our laterbach debugger, we found that the control entered into the relocate_code() function which is called from board_init_f () function. The board_init_f () function is available in board.c file. However, the relocate_code() is implemented in the start.S file. As this is a assembly file, I am not able to understand it completely. The memories that we are using in our board are DDR SDRAM (64MB - Bank0), Boot flash (32MB - CS0), Application flash (32MB - CS1). We modified these parameters in the yosemite.h file and after loading the u-boot.bin file, we are able to see all the memories configured correctly. However, we are not getting the U-Boot prompt on the hyper terminal. Please let me know, If I am missing any thing here. Any help would be greatly appreciated. Thanks and Regards, Srinivas G

[U-Boot] NAND support on AVR32
by David Collier 26 Oct '10

26 Oct '10

If you've seen this before, my apologies - this is my 3rd attempt to post this - it doesn't appear in anything I've downloaded, so I assume it's not getting posted. -------------------------------------------------------------- I thought the whole point of using this linux and u-boot stuff was that whatever you did, someone else had done it first and you just had to copy them. Well I've been caught out :-) I want to ditch using the uSD card at all on our AVR32 board , and use NAND where we have been using uSD. I have a Linux JFFS2 disk working out of NAND - quite easy as Linux pretty much knew how, once you told it you had a chip. But the u-boot seems to have no clue about NAND on the AVR32 - it doesn't set up the hardware to get to it at all, and there's no code set up in the target board header and code files for any AVR32-based board, as far as I can see!!! I did pull the latest files, but I couldn't spot any relevant additions. I have found some stuff in support for other Atmel devices, which seems relevant. I'm totally in the dark about what u-boot can or should do with ecc ..... ------------ So far I've worked out that I've got to 1. in cpu.c add set up MODE3, CYCLE3, SETUP3, PULSE3 registers for cs3 timing. 2. in <target>.c/board_early_init_f add hmatrix_slave_write call to enable nand in ebi 3. in <target>.c/board_early_init_f set up chip select(s) and busy(s) in the GPIO setup to point the right way, and initially turn everything off 4 in <target>.h #undef CONFIG_NAND_LEGACY #define CONFIG_CMD_NAND #define CONFIG_JFFS2_NAND #define CFG_MAX_NAND_DEVICE #define NAND_MAX_CHIPS #define CFG_NAND_BASE 0x0c000000 I'm still pretty woolly about these though CONFIG_MTD_NAND_VERIFY_WRITE CONFIG_MTD_PARTITIONS And I may have missed other compulsory settings 5. create a file called nand.c in the same directory as my <target>.c - I've based mine on the one for the at91sam9261ek. This needs to implement board_nand_init which must set up service routines cmd_ctrl to alter ALE,CLE etc dev_ready to read the "chip ready" status chip_delay - no idea! I note that there are a couple of other entries in the nand_chip that are marked "BOARDSPECIFIC" which I don't set up myself... but I can't see anyone else doing it either! So far I've no clue how the nand.c file gets included in the make of u-boot - is it automatic, or do I need to edit a makefile?

[U-Boot] maybe a priority mistake in mpc85xx_cpu\init.c

26 Oct '10

hi, I notice that in "arch\powerpc\cpu\mpc85xx\cpu_init.c" line 193, version 2010.06: if (! memctl->br1 & 1) The original intention is to check if V bit of BR1 is set or not, but the operator "!" has higher priority than "&" ,I think it should be changed to: if (! (memctl->br1 & 1)) please check this question, thanks!
