[U-Boot-Users] porting to new board: what to do next?
by Benjamin Collar 01 Sep '04

01 Sep '04

Greetings We're porting U-Boot to a new board. We've followed the plan given in the README and have written board.c, flash.c, configs/board.h. We've flashed it and ... well, nothing happens. Nothing at all. Now, I know you'll need more information from me, but I'm not sure exactly what you'll want to know, so for the moment, we'll leave it like that. What I need to know is, how do I find out what U-Boot is up to? Is there a way to debug it from the beginning? I've got it connected serially (unfortunately, our debugger works under windows, so we've got to use HyperTerminal) but nothing shows up at all. Thanks for any help Ben -- Benjamin Collar Siemens AG CT SE 2 Embedded Linux 089-636-53711

[U-Boot-Users] Booting kernel with initrd
by Rainer Brestan (VI/SEA) 31 Aug '04

31 Aug '04

I want to create the linux root partition as image on a fat filesystem and therefore create an initrd which mount this image via the loopback device. Is uboot capable of loading an initrd image and passing it to the kernel ? How to configure uboot for this configuration and which kernel parameters must be used in this case to tell the kernel where to find the initrd im ram ? Regards, Rainer

[U-Boot-Users] serial does not work
by 刘勇 31 Aug '04

31 Aug '04

my card use powerpc 440gx, i use u-boot OCOTEA board. when i arrive the prompt "=>", i can input no char. at last i find that cpu always loops in the function of serial_getc() whatever i press any button. i have no error. cpu-->ppc4xx-->serial.c status = in8 (ACTING_UART0_BASE + UART_LSR); if ((status & asyncLSRDataReady1) != 0x0) { break; } the result of (status & asyncLSRDataReady1) always is zero. i do not know why.

Well if your board has JTAG debug ability, you can step the entire thing. The start up code isn't really all that much. There are many things which could be wrong. What CPU are you using....what board is it close to...variations on a theme tend to be quite easy to port and diagnose errors for...

[U-Boot-Users] New to u-boot: Using M5282EVB
by Riaan van Boom 31 Aug '04

31 Aug '04

Hello everyone, I would like to introduce myself to all u-boot users. I am currently doing development on the Motorola M5282EVB and will ultimately build a custom board (should have been done yesterday already of course:-). It has taken me two weeks now to realize that the M5282EVB port for u-boot is not in fact complete (please correct me if I am wrong). It seems you still need a pre-loader like colilo to initialize the CPU, as the code for initialization was left out. This will not do for me, so I have decided to finish the port (unless someone else has already done that). I will of course make the port available if and when it is finished. I am very new at this, so if anybody has any advice, I would be glad. Regards, Riaan van Boom Siemens Building Technologies Siemens SA Ltd.

Hi all: Could someone tell me if flash is supported by u-boot on the Versatile/PB926EJ-S? If not, how many codes I have to port? Could someone give me a hint or give me some reference document? thx!

RE: [U-Boot-Users] U-Boot DHCP request does not time out.

I've seen the same problem on the TI OMAP 1510 Innovator and a custom board I've worked with that is similar in architecture. >From the Innovator... OMAP1510 Innovator # dhcp Using MAC Address 00:0B:36:00:03:FB BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4 BOOTP broadcast 5 Retry count exceeded; starting again BOOTP broadcast 6 ... Retry count exceeded; starting again BOOTP broadcast 13 ... This lasts for at least a minute for sure. This becomes a problem if 'dhcp' never exits when it is used in bootcmd. -Michael Bendzick

[U-Boot-Users] Multi-file image comment in image.h is misleading
by Jason Milley 31 Aug '04

31 Aug '04

I tried using the "How to Add Files to a SELF Ramdisk" (http://www.denx.de/twiki/bin/view/DULG/HowToAddFiles) instructions to extract a ramdisk from an image until I realized that I am dealing with a multi-file image. # mkimage -l pImage Image Name: Linux-2.4.22 Created: Mon Aug 30 15:56:07 2004 Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 5406339 Bytes = 5279.63 kB = 5.16 MB Load Address: 0x00000000 Entry Point: 0x00000000 Contents: Image 0: 1147513 Bytes = 1120 kB = 1 MB Image 1: 4258811 Bytes = 4158 kB = 4 MB My image file is 5406403 bytes but the total size of the files inside the image is 5406324 (1147513+4258811) which is a difference of 79 bytes. Given that the header is 64 bytes, I am left with 15 that must be related to the multi-file image type. When looking at include/image.h I read the following: * "Multi-File Images" start with a list of image sizes, each * image size (in bytes) specified by an "uint32_t" in network * byte order. This list is terminated by an "(uint32_t)0". * Immediately after the terminating 0 follow the images, one by * one, all aligned on "uint32_t" boundaries (size rounded up to * a multiple of 4 bytes). So my 15 extra bytes were explained as 4 bytes for the size of the first file 4 bytes for the size of the second file 4 bytes for the terminating 0 3 bytes for the padding on the first file (4 - (1147513 % 4)) = 3 Now for the confusion... The second file should also be padded given the image.h comment above and the fact that (4 - (4258811 % 4)) = 1 So why was there no padding? As it turns out, the code in mkimage.c responsible for copying the data files does not add the padding to the last file in the multi-file image. The code I am referring to is in main() and is as follows: for (;;) { char *sep = strchr(file, ':'); if (sep) { *sep = '\0'; copy_file (ifd, file, 1); *sep++ = ':'; file = sep; } else { copy_file (ifd, file, 0); break; } With copy_file defined as copy_file (int ifd, const char *datafile, int pad) Clearly the pad flag is only set when there are more files to copy. My suggestion is a simple update to the comment in image.h to state that the last file will not have any padding applied. BTW: Anyone know if a tool for extracting files from a multi-file image exists or do I have to write one myself? ;) Jason
