[U-Boot-Users] Tqm850 + u-boot-1.1.6 + 2.6 kernel
by Grubmair, Peter 24 Nov '06

24 Nov '06

Without success I tried to use Kernel 2.6.18 on a tqm850. The kernel compiles cleanly to uImage, Uboot loads the image, but then there is no Output at console and after some seconds the board reboots. Are there any known bugs in the kernel which have to be patched, Any special configurations for tqm , any 2.6 kernel versions proved to work in tqm ? Best regards Peter

[U-Boot-Users] 'gd' is getting corrupted.
by Joe Steeve 24 Nov '06

24 Nov '06

I'm porting u-boot to a Sigma Designs em8620L based board. The em8620L is an SOC with an ARMv4t core (pT-110). U-boot gets to the prompt now. Commands in cmd_mem.c, and loads are working fine. However., 'printenv' never worked. My environment is in the 'eeprom'. I did some printfs and found that., the 'gd' is getting changed in between the 'for loop calling main_loop()' in lib_arm/board.c to the 'do_printenv' command that is called from the main_loop(). The commands that I've configured to use are (CFG_CMD_MEMORY | CFG_CMD_EEPROM | CFG_CMD_LOADB | CFG_CMD_LOADS | CFG_CMD_REGINFO). Any pointers to common mistakes could be very helpful. Thanks. -- Joe Steeve Sliceware Private Limited

Networking didn't work on my MPC8555CDS with U-Boot 1.1.6. Comparing to code for the pre-installed U-Boot 1.1.3, I found the PHY init to be different. I've moved the reset to be the first command durint init and that fixed my problem.

[U-Boot-Users] [PATCH] RealView EB support
by Peter Pearse 23 Nov '06

23 Nov '06

Hi The attached gzipped patch adds support for the ARM supplied RealView Emulation Baseboard (EB). Generic cpu code is supplied for Core Tiles (CTs) attached to the board. The cpu code allows U-Boot to be used with any ARM supplied CT e.g. 7TDMI, 1136JF-S, ARM11 MPCore etc. Users wishing to take advantage of the functionality of particular ARM cores will have to add core specific code. Patch made against GIT head - commit 4ef6251403f637841000e0fef9e832aa01339822 on Thu Nov 23 2006 CHANGELOG Added RealView EB board. - Makefile, MAKEALL, include/asm-arm/mach-types.h changes - Add include/configs/realview_eb.h - Add board/realview_eb directory and code files - Add cpu/rvebct cpu directory and code files Signed-off-by: Peter Pearse <ppearse(a)arm.com> --- Regards Peter Pearse

[U-Boot-Users] Toradex Colibri PXA270
by Jason Sachs 22 Nov '06

22 Nov '06

I have been attempting -- unsuccessfully >:( -- to get my Toradex Colibri PXA270 to run the QNX operating system at the PXA270's full rated speed of 520MHz. Please don't ask me to go into the history of this (or ask why I'm posting here rather than asking the manufacturer/vendor in question) unless you can be sympathetic. The HW/OS choice was driven because of a few key features of QNX and of the PXA270; I am not a Linux user nor am I particularly proficient in UNIX in general, and I have my hands full working on my application program without having to worry about the OS or the bootloader functioning correctly. I just want to write my program and run the processor at full speed. Delving into OS/bootloader source code is rather daunting, let alone the possibility of having to get under the hood and make changes. I finally got impatient enough to start poking around the source code of the Colibri port of U-boot. When I reboot my processor, it complains "Missing Colibri config block" -- when I look at the source code, it reaches this point because it's expecting to find a MAC address other than all 0's or all F's, and it quits a setup step which would otherwise set the PXA270 core frequency. Has anyone else here run into this problem and figured out a way to properly set the Colibri config block? --Jason ---- This e-mail and the information, including any attachments, it contains are intended to be a confidential communication only to the person or entity to whom it is addressed and may contain information that is privileged.

[U-Boot-Users] of-tree relocation needed?
by Demke Torsten-atd012 22 Nov '06

22 Nov '06

Hi all, to boot our Linux were using an embedded of-tree (compiled into the u-boot image). The kernel wants to access this tree very early, but fails, because the tree is not within the first 8(16?) Mbytes of the address space. I think, the of-tree should be moved below the CFG_BOOTMAPSZ limit, so that the kernel can access theof- tree at start-up. Is there any other possibility to relocate the of-tree? Best regards, Torsten

[U-Boot-Users] Reading out version_string from a binary
by Fredrik Roubert 22 Nov '06

22 Nov '06

Hi! I use U-Boot (1.1.4) on a custom PowerPC (MPC8347) based board, and from my application I need to read out the value of version_string from the U-Boot binary, for logging. I've written some code that does this (see attached sample program), but would like some comments if someone has suggestions on how to do it more robust. On MPC83XX, version_string is stored at the beginning of .rodata, so if only the offset for .rodata is found, reading out version_string is quite straightforward. The offset of .rodata changes, however, when code is added or removed from U-Boot. I've found that an offset is being written at the end of start.o, from which it is possible to calculate the offset of .rodata, and even though this works for my current needs, it's hardly what one would call a robust solutions. Does anyone have ideas about a better way to do this?

[U-Boot-Users] 834x UPM Read access RAM Array (stuck?).
by Marc Leeman 21 Nov '06

21 Nov '06

I'm trying to program the UPM A on the 8347E processor. Next to having bus errors while writing from Linux (RAM words for HPI are not correct yet, but that's something I have to figure out), I'm having problems with reading the RAM words back out for testing/debugging/verification. As the upm_config of for the 83xx processors is not yet implemented, I am using the following code as described on 10-63 to program the UPM [1]: This is a write cycle (working): inline void upm_write32(u32 data) { volatile immap_t *im = (immap_t *)CFG_IMMRBAR; u32 mdr; u32 mad; /* read the current MAD */ mad = (im->lbus.mamr & MnMR_MAD_MSK); /* set MDR */ im->lbus.mdr = data; /* Read the MDR back to ensure the data has been saved */ mdr = im->lbus.mdr; /* dummy write */ *((u32*)im->sysconf.lblaw[1].bar) = 0xffffffff; putc('.'); while((im->lbus.mamr & MnMR_MAD_MSK) == mad){ /* dummy write */ *((u32*)im->sysconf.lblaw[1].bar) = 0xffffffff; putc('#'); } } From all the tests I've done, the MAD is incremented what should mean that the write to the UPM RAM array was successful. Filling out the array itself is done with the following code: void init_upma(void) { volatile immap_t *im = (immap_t *)CFG_IMMRBAR; u32 mad; u32 i; /* 1. Set up BRn and ORn registers, done during cpu_init and * set in the platform header file. */ /* 2.

[U-Boot-Users] PXA27x USB support?
by David Snowdon 21 Nov '06

21 Nov '06

G'Day, Has anyone given PXA27X USB support a go? If not, I'm probably going to need to have a crack. Anyone else have a need for it? Any sage words of advice from someone who's looked at USB for another platform? Cheers, Dave.

[U-Boot-Users] u-boot hanging
by Ram 21 Nov '06

21 Nov '06

Hi, I had posted a query regarding hanging of u-boot when a return is made from a standalone application. Does this have anything to do with the size of the standalone application?. Should i specify that somewhere?. Is there a maximum size of an App. hello_world example works fine for me. However when i do the return from my custom standalone application, u-boot hangs. This behaviour happens 7 out of 10 times. (Sometimes, it works well, most times it doesnt). Do we need to do something "Special" before returning back?. Please do advice. All im doing is while (!tstc()) ; ch = getc ( ); printf ("Returning\n") ; return (0) ; Regards, sriram
