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.

This patch provides port I/O commands for architectures that support them. AFAIK, the only current architecture using a separate IO space is IA32 (aka x86).

[U-Boot-Users] RE: Why S-Records?
by Wells, Charles 30 May '03

30 May '03

Rupesh, I always view the choice of S-records (or Intel hex or whatever) vs. binary records as being a matter of line bandwidth. The problem is, of course, that the ASCII hex characters take a bit more than twice as long to send. Note that even in the ancient minicomputer days (say 1969), the DEC paper tape loader was a binary loader. The problem here was that the terminal of choice was an ASR33 and loaded programs at 10 bytes per second. Even short programs took a very long time to load. A PDP11 might have 16k bytes of memory, so a 6k program was not unreasonable. This would take over 10 minutes to load. ASCII-based download formats became popular with the advent of microprocessors which originally had very limited memory but faster serial ports. The micro may have only 1k of program RAM and the serial port would run at 960 characters per second. So, the entire RAM could be loaded in just over 1 second. The problem was that the serial port used to download a program was also used as the console device and therefore had an ASCII terminal monitoring the line as well. If you sent binary over the line, it was echoed you would get unsightly garbage printed on the console. You also had to put up with the irritating noise of the bell. Worse yet, the binary characters would put VT100-style consoles into strange modes that you couldn't recover from. So, if you split one binary character into two ASCII hex characters, you never had to deal with a messy or noisy display. You could also just look at it and read it. Some of us got quiet good at this. Error detection and control is a totally different matter. If you're downloading a program, you always need to know that it got down there correctly, so you always need error detection (and possibly control). My preference is to add the extra error detection characters in the definition of the loader records, regardless of whether these loader records are ASCII or binary. This way you can move between physical transport methods (e.g., raw serial ports or TCP/IP/Ethernet) and simply not worry about whether the line discipline has error checking or not. With the speed of modern communications lines, the few percent of overhead for the checksums just doesn't matter. Just my $0.02. Regards, Charlie

[U-Boot-Users] Why S-Records?
by Rupesh S 30 May '03

30 May '03

Hi, Pardon me if this is out of scope in this groups.. The discussion is about usage of S-Record files for Downloads instead of Binary file. Generally S-Record Downloads are used when the medium of communication is Serial Port , which has no Error Checking mechanism inbuilt in hardware. Whereas when we consider the Network download throgh Ethernet, most bootloaders (u-boot as well) does a binary download. Is this because the Ethernet hardware has a Error Checking mechanism inbuilt ? If yes, even using a USB hardware for download also can use Binary instead of S-Records?? Please comment on my arguments? Rupesh

[U-Boot-Users] timers
by Gupta, Kshitij 30 May '03

30 May '03

hi, If you don't use the interrupts (i.e #undef CONFIG_USE_IRQ) and the timers which we have on board downcount timers which generate interrupts when they reach count of 0, then is it possible to maintain timers ?? If the interrupts are disabled then when the timer wraps around (auto reload) then there is no one to increment the wrap count, thus we loose the time. The only time I can see this working is when we are sure that we will get a get_timer() call every time before the timer wraps. I saw the code for smdk2410(Arm920t based) board and for this board the interrupts are disabled. If anyone can please guide me on this problem. regards -kshitij

RE: [U-Boot-Users] interrupts.s/udelay accuracy.
by Woodruff, Richard 29 May '03

29 May '03

Perhaps its not worth worrying about in this context. Several of the ports use a simple split /1000 /1000 along with CFG_HZ to convert microseconds to ticks. When I grepped the config files I saw a pretty wide range of raw frequency's including some below the megahertz range which the /1000's are normalizing for. A simple grep of the sources also shows many functions use udelay with input ranges from 1 to 100,000,000. I called out ethernet, but I was more wondering about protocols which might like to delay. In fairness most if not all which use this correction are in the mhz range. In my case I can set the tick rate for the free running decrementer in the KHz range or in the Mhz range. To allow for a variable CFG_HZ setting it would be nice if the normalization did not assume megahertz, and nice to allow for a wide udelay input, such that tmo *= CFG_HZ, would not overflow a 32 bit number. I had used some code in the past which did use long long's to normalize from various input levels, sec/milli/micro/nano, and converted it to clock ticks with out dropping bits. When I reached the point of wondering if I should use a bit more code, I started to wonder if it was worth my time to even do it...thus I asked if anything really needed it.

[U-Boot-Users] interrupts.s/udelay accuracy.
by Woodruff, Richard 29 May '03

Hello, About how accurate in practice does the udelay() & other time base functions have to be? especially for ethernet/networking devices? I've currently got enough of the basics ported for my arm925/omap based board such that it comes to a u-boot shell, and things like sleep x work....I was thinking about moving on to getting my ethernet device working, and am a little uneasy about the way I (and it appears several others) have hacked the time conversions. Does gcc provide some nice 64 bit integer manipulation libraries which aren't huge? If so I'd be tempted to bring in some code which does the right thing and doesn't have to worry about integer over/under flows. Regards/Thanks, Richard W.

[U-Boot-Users] mpc824x/start.S
by Matthew McClintock 28 May '03

28 May '03

I have a question for everyone on the list. I am booting u-boot on a custom mpc824x board (utx8245) and I have run into a minor annoyance. In start.S you have the following code in relocate_code: relocate_code: mr r1, r3 /* Set new stack pointer */ mr r9, r4 /* Save copy of Global Data pointer */ mr r10, r5 /* Save copy of Destination Address */ mr r3, r5 /* Destination Address */ #ifdef DEBUG lis r4, CFG_SDRAM_BASE@h /* Source Address */ ori r4, r4, CFG_SDRAM_BASE@l #else lis r4, CFG_MONITOR_BASE@h /* Source Address */ ori r4, r4, CFG_MONITOR_BASE@l #endif lis r5, CFG_MONITOR_LEN@h /* Length in Bytes */ ori r5, r5, CFG_MONITOR_LEN@l li r6, CFG_CACHELINE_SIZE /* Cache Line Size */ /* * Fix GOT pointer: * * New GOT-PTR = (old GOT-PTR - CFG_MONITOR_BASE) + Destination Address * * Offset: Now I am curious why when you are running in debug mode you choose to copy everything from CFG_SDRAM_BASE, while working normally you copy it from CFG_MONITOR_BASE. For us there is nothing to be copied at CFG_SDRAM_BASE and u-boot crashes right after it relocates the code and jumps to the copied point. We get around this obviously by doing the following: relocate_code: mr r1, r3 /* Set new stack pointer */ mr r9, r4 /* Save copy of Global Data pointer */ mr r10, r5 /* Save copy of Destination Address */ mr r3, r5 /* Destination Address */ #ifdef DEBUG lis r4, CFG_MONITOR_BASE@h /* Source Address */ ori r4, r4, CFG_MONITOR_BASE@l #else lis r4, CFG_MONITOR_BASE@h /* Source Address */ ori r4, r4, CFG_MONITOR_BASE@l #endif lis r5, CFG_MONITOR_LEN@h /* Length in Bytes */ ori r5, r5, CFG_MONITOR_LEN@l li r6, CFG_CACHELINE_SIZE /* Cache Line Size */ /* * Fix GOT pointer: * * New GOT-PTR = (old GOT-PTR - CFG_MONITOR_BASE) + Destination Address * * Offset: This is a hack, and it cannot be merged back into u-boot so I was wondering if there was a more eloquent way to do this, something else I am missing that will make my program work while in debug mode with an unmodified start.S. Thanks for your time, Matthew

[U-Boot-Users] New x86 board booted...now the hard part
by Marc Singer 27 May '03

27 May '03

Yipee! It boots. I have a few questions. 1) Daniel, do you think that the 'fs' overrides in mem_init are necessary when ds == fs? 2) How would you expect to override mem_init on another x86 board? It seems to me that we'd be better off with a BSP entry point for RAM initialization that calls the appropriate library function(s). 3) We ought to be able to share serial driver code between x86 and the risc processors as long as we abstract port accesses the way that the Linux kernel does. Has this been discussed?

[U-Boot-Users] linux doesn't boot when CS for initial cache disabled
by Thomas Schäfer 27 May '03

27 May '03

Hi all, I'm testing with an IBM Walnut board (PPC405GP) with u-boot 0.3.0 and 2.4.17 kernel from Montavista. After booting u-boot and loading the kernel via tftp, I submit the following commands on the console: => setdcr 12 0012: 00000004 ? 7 0012: 00000007 ? . => setdcr 13 0013: 400da000 ? 0 0013: 00000000 ? . This disables CS7, which is used for the temporary stack in my configuration. After that, I can still load a linux kernel via tftp, but it hangs in the early bootup sequence when turning the MMU on. I found that the data cache for the temporary stack has to be flushed and disabled before the CS for the temporary stack is disabled. I changed the u-boot code at this point and everything worked fine. Here the changes in the code are summarized: /board/walnut405/walnut405.c: - The function board_pre_init was divided and a new function board_pre_init_r was created, which contains the EBC programming /include/common.h: - The prototype for board_pre_init_r was added /cpu/ppc4xx/cpu_init.c - In the cpu_init_r function, data cache is flushed and disabled first. After that the CS for the temporary stack is disabled and board_pre_init is called to program the EBC. This means that the EBC is programmed later in the boot process than before, but EBC programming seems not to be necessary that early (with the exception of the CS for the NVRAM, where the programming was left in board_pre_init). - In the cpu_init_f function, the EBC programming code was moved into cpu_init_r. I had to do those changes, because all available CS lines are used on one of our custom boards. Now I have the possibility to use a CS for the temporary stack in early boot stage and for hardware devices after relocation. If the changes are of some use for the project, I can provide a patch.

[U-Boot-Users] U-BOOT+GDB+BDI
by Karoliya, Abhishek 27 May '03

27 May '03

Hi , I have working U-boot for my 8245 board ,the porting of which required the BDI. Now with this working image , I am trying to use GDB + BDI for source level debugging to add other components in U-boot. The problem is when i start GDB {ppc_82XX-gdb u-boot -s u-boot.map} and I single step in start.S file , it works fine until the sync instruction under boot_warm label but as soon i single step it , the gdb goes blank{as in it returns to new line without printing } although the u-boot comes up to prompt as seen at serial console. where I am going wrong ...... Thanks Abhi

Hi. I have just installed the great rpm uucp to use cu. so I make cu -s 9600 -l ttyS1 --nostop. Unfortunately, it seems that what I type isn't sent to my board !! It works fine with minicom. It seems that it is because of the flow control. In minicom I choose no software and no hardware flow control to make it work. How can I do the same with cu ? My serial cable is only RX TX & GND.

[U-Boot-Users] Shared serial driver
by Marc Singer 27 May '03

27 May '03

I now remember why there is an x86 specific serial driver. Unlike every other chip, the x86 has a separately mapped I/O port address space. Sharing the driver will require some inline functions or macros to bridge the gap. If continue to take from the Linux kernel model, there are CPU specific macros to read and write in the IO space. I also seem to recall that the spacing of IO addresses is different on each CPU. Some are forced to be 32 bit aligned while others may be word aligned. There is a little bit of work to fit all of the pieces together. Fortunately, the 16550 driver is simple enough to be a reliable test bed. Are you good with this path? Cheers.
