hi, all: I am try to build u-boot image for board "ep7312", and process pause with error: ---------------------------------------------------------------------------- ---------- $make ....... m7tdmi -Wall -Wstrict-prototypes -c -o cmd_scsi.o cmd_scsi.c In file included from cmd_scsi.c:33: /u-boot-1.0.0/include/asm/processor.h:52: parse error before `1' /u-boot-1.0.0/include/asm/processor.h:52: warning: no semicolon at end of struct or union /u-boot-1.0.0/include/asm/processor.h:54: parse error before `}' /u-boot-1.0.0/include/asm/processor.h:58: field `insn' has incomplete type make[1]: *** [cmd_scsi.o] Error 1 make[1]: Leaving directory `/44b0ii/u-boot-1.0.0/common' make: *** [subdirs] Error 1 $ ---------------------------------------------------------------------------- ---------------- (My build enviroment is cygwin) By way, I post line 52 of processor.h ... union debug_insn { u32 arm; <---- line 52 u16 thumb; }; ....

[U-Boot-Users] OMAP1510 Innovator kit booting questions
by Grigory A. 27 Dec '03

27 Dec '03

Hi! I am using U-Boot 1.0 on my OMAP 1510 Innovator kit. Could someone give me answer on my 2 questions? 1. My platform is ARM9 and I am using separate Linux kernel and RAMdisk images. I am booting from RAW flash. In file ./lib_arm/armlinux.c there is function do_bootm_linux() that works with initrd. But at least for separate images initrd is not copied anywhere. Why? And this means that for any ARM platform initrd won't be copied if user will use separate images? So I solved this by putting memory copying call - and it now is working well. 2. Next - I am using autoboot mode with 3-5 seconds of bootdelay. But 1 u-boot seconds is approximately 15-20 of real seconds. Yes - this is board specific - maybe some clock setup missed - (by me?) or PLL settings - so could someone help me with it? Only that I have changed - I've switched to use UART2 for serial communication - it is working well - I don't think that it has got any influence to board speed. Thanks for answers. -- Best regards, Grigory mailto:Ryhor@tut.by

Welcome... Read the DULG manual (ignore the 8xx references, most of it applies to any target) http://www.denx.de/twiki/bin/view/DULG/Manual * Cygwin is a painful way to build u-boot. You are much better off using linux. People have worked at supporting building u-boot under cygwin, but it is not a well supported option and I'm not sure if it even works. * Yes, you need an ARM cross compiler before you will get anywhere. * Everything you need except the OS is available from the www.denx.de web site. Your best approach is to set up an environment that closely mimics Wolfgang's, which means using ELDK (provides your cross compilers). Supported operating systems (note Cygwin is not listed): http://www.denx.de/twiki/bin/view/DULG/ELDKSupportedHostSystems * If your environment is set up correctly and all the proper support software is loaded and running, you won't have to worry about what is in arm_config.mk. Chasing changes in the makefiles is going to eat up much more time than setting up a compatible environment. gvb > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net]On Behalf Of liang a > lei > Sent: Wednesday, December 24, 2003 1:05 PM > To: u-boot-users(a)lists.sourceforge.net > Cc: liangalei(a)sjtu.edu.cn > Subject: [U-Boot-Users] Hi, I am a new > > > hi, all: > > Happy Christmas.

hi, all: Happy Christmas. On this I start my step to U-Boot, -- it's very lucky ?:-), :-S I have installed Cygwin on Win2000, and U-Boot source, and have a overlook to README, then I type my first command to U-Boot ---- just for a test $ make ep7312_config rm -f include/config.h include/config.mk Configuring for ep7312 board... $ (No more information to be displayed anymore?) Is it wrong? And I don't understand ".mk" file exists at top-level "eg. arm_config.mk", what it be used? Do I need to download cross-compiler for arm7? Any good paper of "Compiling U-Boot" dedicated for arm CPU (like ep7312, lurk, etc.) (I am trying to port U-Boot for s3c44b0II chip)? thanks Liang Alei

by ganapathi 24 Dec '03

[U-Boot-Users] flash configs
by labblelabble 22 Dec '03

hello : I now transport the u-boot to my own system ,and i take the rpxlite as an example. when it is to config the flash memory system ,i see the following items in the rpxlite.h: #define CFG_MAX_FLASH_BANKS 1 /* max number of memory banks */ #define CFG_MAX_FLASH_SECT 19 /* max number of sectors on one chip */ and i can.t understand it .how can i get the two args of my own flash memory systems .and if the number of SECT is just the number of flash memory blocks >?????? wish someone could give my some hint about it ...thanks a lot!!!
