[U-Boot-Users] LCD on OMAP2430
by Goswami Jigisha-ejg014 29 Mar '06

29 Mar '06

Hello, Please disregard my previous message with html. I apologize for that. I am working on getting my target LCD up with U-Boot. My board is OMAP2430 and the display controller is that of OMAP2430. The LCD is an 18 bit QVGA TFT. Here is what is changed in U-Boot: 1) I added a new file called omap2430fb.c, which is my Display Driver, and put with my board specific files. I took pxafb.c as reference. 2) I declared my panel structure in lcd.h file 2) I defined CONFIG_LCD in my board config file. 3) I wanted to use the cmd_bmp command so I added CFG_CMD_BMP to my board config file as well. After I built my changes with U-Boot and flashed the image, I turn on the board and get the following message: U-Boot 1.1.3 (Mar 28 2006 - 17:48:08) U-Boot code: 80E80000 -> 80EA1450 BSS: -> 80ECC518 OMAP2430C-GP revision 0, PRCM #5A TI 2430SDP Base Board + 0.1 Version + mDDR RAM Configuration: Bank #0: 80000000 128 MB Bank #1: 88000000 0 kB Flash: 64 MB NAND:64 MB *** Warning - bad CRC, using default environment This message is coming from common/env_common.c file. Can anyone help me identify the mistake? Is that all I have to do to enable my target LCD within U-Boot? My goal is to be able to write images on the LCD verify if it is OK. Thanks, Jigisha

[U-Boot-Users] VCMA9 compile error with nand support
by Joe Culler 29 Mar '06

29 Mar '06

Hi there, Since vcma9 board supports booting from NAND. I enabled CFG_CMD_NAND for CONFIG_COMMANDS, then I tried to compile it, I got: board/mpl/vcma9/libvcma9.a(vcma9.o): In function `nand_init': /home/joe/u-boot/board/mpl/vcma9/vcma9.c:182: undefined reference to `nand_probe' common/libcommon.a(cmd_nand.o): In function `nand_dump': /home/joe/u-boot/common/cmd_nand.c:57: undefined reference to `nand_read_raw' common/libcommon.a(cmd_nand.o): In function `do_nand': /home/joe/u-boot/common/cmd_nand.c:225: undefined reference to `nand_info' /home/joe/u-boot/common/cmd_nand.c:225: undefined reference to `nand_curr_device' /home/joe/u-boot/common/cmd_nand.c:260: undefined reference to `nand_curr_device' common/libcommon.a(cmd_nand.o): In function `do_nandboot': /home/joe/u-boot/common/cmd_nand.c:376: undefined reference to `nand_info' make: *** [u-boot] Error 1 Looks like vcma9 with nand support is broken. Does anyone know how to fix it? Thanks. Regards, Joe.

[U-Boot-Users] Flash Erase Problem...
by Kiran Jammula 29 Mar '06

29 Mar '06

Hi, We are using U-boot-1.0.0, When we use erase command it is showing all the sectors earsed successfully. But when we try to copy images in that area it is showing that one particular are is not erased. This kind of behaviour is very rare in occarance. When we erase the same flash with JTAG adapter it is not giving any problem. Plase help us in this regard... Thanks in advance.

[U-Boot-Users] arm920t memcpy
by claudio123 29 Mar '06

29 Mar '06

arm920t The same code base builds and correctly executes when compiled with the 2.95.3 compiler. When the same code base compiles with 3.1.1 compiles fine, but crashes on memcpy instructions. Note that makefiles are identicals. Any idea? -- View this message in context: http://www.nabble.com/arm920t-memcpy-t1359736.html#a3642944 Sent from the Uboot - Users forum at Nabble.com.

[U-Boot-Users] Linux Hangs
by Ganesh Ramachandran 29 Mar '06

29 Mar '06

My Name is Ganesh Ramachandran. I have a Problem in U-Boot Loaders. As Follows, I am using ARM Integrator CP Configuration for U-Boot Loader. I am using ARM Real View Simulator and Real View Debugger. My kernel Version is 2.6.16 and U-Boot Loader Version is 1.1.4. I am attaching my Configuration Header File with this mail. Just have a look. I am using ARM Cross Compiler for creating U-Boot Loader files( u-boot.Bin, u-boot). That was getting created successfully. I am using AFU.axf utility to dump the root file system and kernel. I am getting the following messages in Telnet while executing.. U-Boot 1.1.4 (Mar 28 2006 - 19:02:25) U-Boot code: 01000000 -> 010134B0 BSS: -> 01016F98 RAM Configuration: Bank #0: 00000000 16 MB Flash: 16 MB *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 Integrator-CP # bootm 0x24040000 ## Booting image at 24040000 ...

Uncompressing Linux....................................................................... done, booting the kernel. After that Linux Gets hanged. I read the FAQs from several websites, They said me to do following changes, * Check the IMAP_ADDR, CFG_IMMR for same. But I don't find any IMAP_ADDR or CFG_IMMR variables in my ARM configuration files. Since, Both are not for ARM that I read in another website. * Check the Kernel Command Line. I gave root=/dev/mtdblock0 console=ttyAMA0 mem=128M for both Kernel and Configuration files. And Root File system also has those two files. No other Comments gave any good information than above one. More They above comment is also for PPC Version with Kernel 2.4.X and U-Boot 0.4.X. But I am using latest versions. Please let me know where I am doing mistakes, Where will be the problem persists. Sorry for the inconvenience. Thanks & Regards, P. Ganesh Ramachandran

[U-Boot-Users] help understanding bd_t passing
by Martin Hicks 29 Mar '06

29 Mar '06

Hi, I've got a ppc405gp board that has been running U-boot/Linux for a while, but using a silly hack in cmd_go to pass in our arguments. I haven't quite figured out how the kernel gets the bd_t pointer. I"m also confused by the seemingly inconsistent bd_t structures between the kernel and u-boot. So what the hacked version of u-boot (hacked by someone else) currently does is declare a simple bd_t in cmd_go and pass the address of that as the only parameter when we jump to addr. ((void (*)(void *))addr)(&bd_struct); Obviously, I'd rather just use the normal method. It looks to me like the parameters to addr() ends up being the load address of the kernel, but when we get to ppc4xx_init() in the kernel it looks like it *should* be a pointer to bd_t. Any hints as to how this all works? I've looked at walnut as an example, but the bd_t defined in the kernel looks like it starts with bi_s_version[4] and bi_r_version[30], which look to be at some offset inside the bd_t defined in u-boot.h Confused, mh -- Martin Hicks || mort(a)bork.org || PGP/GnuPG: 0x4C7F2BEE

So, I tried reverting to the virgin U-Boot-1.1.4 source, and only made the changes that I need to make my memory work, and I am still getting the same output from the kernel. What could be causing this? Could it be my memory configuration? Please help!!!!! Oh, also, I can boot the same kernel using PIBS, and everything boots fine. It's only under U-Boot that I get this issue. Thanks, Jeff Stevens __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Hello all, I'm developing a boot loader application for an Embedded Planet Power PC 5200 based development board ep5200 and wanted to use U-Boot to do the booting portion. I was wondering if anyone out there has invented this wheel first however and had the necessary cpu and necessary board information for the U-Boot. Thanks, Mike
