I was trying to load linux-2.4.4 in FADS860T board using u-boot-1.0.0. I have settted environment variables like ipaddr,serverip,ethaddr,bootargs bootfile and saved the environment. Then,i typed tftpboot to download image from server. Then,i typed bootm to start the booting process. System is stucked by showing "Uncompressing Kernel Image ... OK" sequence of these events r given below.can u please suggest, what i need to do to come out from this. Thank you.

That does not make any difference, or does it? fro example, use DDD as GUI frontend with GDB - but it's still GDB that will actually perform the debugging, so why shoud it behave differently?

[U-Boot-Users] Need Help w/ PPC Boot
by Jerry Walden 31 Dec '02

Greetings: I apologize in advance if this is a stupid question, or a question with an obvious answer. The fact is that I have place linux on and ARM, and an X86 board, however never on a PPC platform. In fact I have very little experience with the PPC, and RISC processors in general. I am trying to trace my way through the u-boot code - since I do not have access to an in circuit emulator, I am somewhat hindered. However I do have the capability to turn on a LED via a GPIO register. So I am tracing through the code in a "burn an learn" fashion. I have a routine called "led" that turns on an led. The code below is from start.S from the u-boot distro from the cpu/ppc4xx, my processor is a ppc 405GPr. The below code turns the LED on. Note the branch instruction that branches to some code to turn the led on. If I put the branch instruction AFTER the "mtmsr r4" instruction the LED does not turn on. I cannot figure out what is going on. If anyone has any recommendations on documentation to read (I have the 600 page "green book") or if there is something I am obviously missing (i.e. not being familiar enough with how a risc processor works) any advice is welcome. . = EXC_OFF_SYS_RESET .globl _start _start: /* Clear and set up some registers. */ addi r4,r0,0x0000 mtspr sgr,r4 mtspr dcwr,r4 mtesr r4 /* clear Exception Syndrome Reg */ mttcr r4 /* clear Timer Control Reg */ mtxer r4 /* clear Fixed-Point Exception Reg */ mtevpr r4 /* clear Exception Vector Prefix Reg */ addi r4,r0,0x1000 /* set ME bit (Machine Exceptions) */ oris r4,r4,0x0002 /* set CE bit (Critical Exceptions) */ /* the LED will turn on if I branch here */ b LED mtmsr r4 /* change MSR */ /* the LED will NOT turn on if I branch here */ /*b LED */ addi r4,r0,(0xFFFF-0x10000) /* set r4 to 0xFFFFFFFF */ /* dbsr is cleared by setting bits to 1) */ mtdbsr r4 /* clear/reset the dbsr */

[U-Boot-Users] How to start
by Martin Winistörfer 31 Dec '02

31 Dec '02

Hi, I'm working on a MPC5xx microcontroller and intend to add some features for the MPC5xx to this project. But before I can start I have some questions about the project: - Have there been any effort to implement a MPC5xx port already? I've seen the MPC8xx seems to be well supported. Unfortunatly I don't know this uC well, but it seems that both don't have a lot in common. - I've read the recommended documentation (README, some source...) but what I'm missing is something which discribes the minimal interface between the board and cpu specific part of the code and the actual u-boot code. Something like an API documentation. Is such a document available? The README.console file lists some interface functions. But what's with the other features? What function do I have to provide to get a running system? What I would like to set up is a minimal configuration like this. Essential parts -> A serial interface (for the console) -> r/w memory (memory functions like mm, md...) -> Selecting load adress and go Advanced features -> Download image -> Test, burn, erase flash* -> Test RAM Best regards, Martin * Currently we have a customer board with Flash, RAM and other periphery. -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet.

> Minicom is broken. It cannot be used for s-record download, except by > inserting unacceptable delays. If you have to use something over the serial cable, consider C-Kermit. I compiled for my Linux and it works great. Because it is scriptable (althought in a strange way), I can even automate things. My C-Kermit for example connects to my BDI2000 (over TCP/IP, not serial, it can do both), erases the flash and loads the new bootloader automatically: #!/usr/bin/kermit + .bdihost = bdi .prompt = bdi> .image = /bdi/armboot .image_start = 0x000000 define failquit { input 1 xxxxxxxxxxxxxxx close echo echo \%1 exit 1 } set input echo off set exit on-disconnect on ; Automatic exit on connection loss. set telopt start-tls refuse ; Do not use START_TLS option set telopt authentication refuse ; Do not use AUTH option set telopt encrypt refuse refuse ; Do not use ENCRYPT option echo "Connecting to \m(bdihost) ..." set host \m(bdihost) 23 /telnet ; Force Telnet protocol negotiations if fail exit 1 input 1 \m(prompt) if fail failquit {No prompt from bdi} define erase_flash { xecho "Erasing block \%1 ..." lineout "erase \%1" minput 4 {Erasing flash passed} \# if fail failquit {No answer to 'erase' command.} if ( = \v(minput) 2 ) failquit {Could not erase block \%1.} echo " done!" } erase_flash 0x000000 xecho "Burning image \m(image) ..." lineout "prog \m(image_start) \m(image)" minput 30 {Programming flash passed} \# if fail 1 failquit {No answer to 'prog' command.} if ( = \v(minput) 2 ) failquit {Could not burn image \m(image).} lineout "reset" echo " done!" close quit I'm using similar scripts to update my kernel and my jffs2. Basically I just change the .image, .image_start and the erase_flash lines.
