[U-Boot-Users] how can I boot u-boot from 0x40000 in flash instead of 0x0000
by Ray Zhao 14 Jul '05

14 Jul '05

My board need keep the first 0x40000 flash for special purpose. Is it easy to modify the u-boot to load itself from 0x40000 instead from the 0x0000? Any help is appreciated. Ray -- --------------------------------------------------------------- Everything that has a beginning has an end.

[U-Boot-Users] Activating hush shell
by Andreas Engel 14 Jul '05

14 Jul '05

Hi, I'm trying to switch from the old shell to hush on a custom ARM board with u-boot 1.1.2 by just defining CFG_HUSH_PARSER and CFG_PROMPT_HUSH_PS2 in the config file. However, u-boot now doesn't really wait for user input, but endlessly prints its console prompt. Before digging deeper into the problem with a debugger: do I need to do anything else beyond just enabling hush? Andreas

Hi,I have some question on gdb-debugger with BDI2000.My board is like MPC8260ADS,ppcboot version is 2.0.0. I have programed ppcboot.bin into flash with BDI2000.

[U-Boot-Users] PCI PNP
by C.Gillan＠ecit.qub.ac.uk 14 Jul '05

14 Jul '05

I am trying to understand the role of the the hash define CONFIG_PCI_PNP in the context of building a card (8540 based) with a PCI interface such that it will sit inside an Intel PCI runing Linux. I see several examples of PCI usage in the U-Boot source code but its not clear whether any of these correspond to my situation. Recently the PN62 was mentioned on this list - it is such a card ? Where can I find more documentation on it ? My guess is that the PNP code is only used when the 8540 is acting as a "master" and configuring devices that are an "extension" to it on the PCI bus. In my case, I am expecting the Intel PC's motherboard BIOS to configure the PCI controller on my 8540. So, all I need to do, I think, is configure the ATMUs to map PCI addresses into 8540 Ocean addresses ? Thanks in advance, Charles Gillan Inst. for Elect. Comms and Info.

[U-Boot-Users] 2.6.12 with u-boot-1.1.2 on versatile
by Shakthi Kannan 14 Jul '05

14 Jul '05

Greetings! System details: Board: Versatile-ARM926Ej-S Cross-toolchain: 3.4.3 Linux kernel: 2.6.12 u-boot: 1.1.2 I have been able to successfully cross-compile u-boot, program it to NOR flash, and run it from the SDRAM. I have also cross-compiled the kernel to create the vmlinux file. I have used the config file provided in arm.com site for this board: http://www.arm.com/linux/linux_download.html I then created uImage using: # arm-linux-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin # gzip linux.bin # ./mkimage -A arm -O linux -T kernel -C gzip -a 0xc0008000 -e 0xc0008000 -n "Linux Kernel Image" -d linux.bin.gz uImage The uImage is programmed at 0x36000000 in NOR flash. But, When I try to run the kernel from u-boot it hangs at the following: ## Booting image at 36000000 ... Image Name: Linux kernel image Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 1112206 Bytes = 1.1 MB Load Address: c0008000 Entry Point: c0008000 Uncompressing Kernel Image ... OK Starting kernel ... When I looked through the debugger (Lauterbach), it hung at a virtual address inside panic.c. If anyone can tell me as to what I am doing wrong, and how I can get the kernel up and running on this board, it will be really helpful.

[U-Boot-Users] [PATCH] sinclude board specific make fragment
by Murray.Jensen＠csiro.au 14 Jul '05

14 Jul '05

This patch "sinclude"s (i.e. it is allowed not to exist) a make fragment from the board specific subdirectory, to allow a port to have board or platform specific targets (which may or may not be added to ALL var - see previous patch). for example - install, or in the case of my 8560 based board, I build a separate file image of the "boot page".

[U-Boot-Users] CF 5282 fec.c
by Jens Scharsig 13 Jul '05

13 Jul '05

Hello I'm new on U-Boot and work on a MCF5282 port. I have modify the cvs source and U-Boot runs on my own MCF5282 board (I get a promt on serial line). But i get "Tx not ready" and "Tx Timeout" messages for each ethernet access. I discover the fec.c, and find out that only 10MBit haft duplex is use. Is there in implementation for full 100MBit use? regards Jens Scharsig Internet: http://www.bus-elektronik.de

[U-Boot-Users] Problem about sdram initialization！
by junping feng 13 Jul '05

13 Jul '05

Hi,I have a little problem with the ppcboot startup,the BDI2000 can program ppcboot.bin into FLASH .Board information can print through serial interface after the first initialization of board now. But when it run to the function relocate_code(in the /cpu/mpc8260/start.s),it don't run continually. Through LED on the board ,I find that it stops at the code below: addi r0, r10, in_ram - _start + EXC_OFF_SYS_RESET mtlr r0 blr in_ram: The size of SDRAM size is 16MB,flash is 8MB,CPU is MPC8250,and my costum board is like the board MPC8260ADS.Othe infomation with my board is below: CLKIN:33M MPTPR:0x10 PSRT:0x1900 BR2(control SDRAM): 0x0000 0041 OR2:0xFF80 3080 PSDMR: 0x2869 A452 0x0869 A452 0x1869 A452 0x4069 A452 SIUMCR：0x0A20 0000 Please give me a hand.

[U-Boot-Users] Side-effects when adding debug output
by "Häpe, Sebastian, HRD/AB" 13 Jul '05

13 Jul '05

Hi everybody! I have a little problem with u-boot and I don't know if I am the reason for it. It's the following: I want to add some extra output to the functions do_bootm and do_bootm_linux because I have problems with the kernel parameters. So i added a few printf's to the functions mentioned above. The things that happen now, I do not understand: Parameters of called functions (e.g. like the "int argc" parameter) suddenly change to random values. How could that be caused? Has it something to do with the stack (overflow or undefined behaviour when using "printf")? Or should I use any other function for creating output? (instead of using the BDI2k) Greetings, Sebastian
