Linux/dumpe2fs showed that the bootable [Fedora-2.6.15] 2GB SD cards had inode_size = 128, whereas the delinquent [Ubuntu-2.6.27] SD cards had inode_size = 256. Adding a -I 128 switch to mkfs.ext3 in the script that prepares and loads the SD cards solved the problem. That is, our SBCs can now boot from Ubuntu prepared SD cards. However, this brings up the point that, somewhere along the line, the default inode_size for SD cards is no longer 128 bytes. It could be double, quadruple or more. There is some suspicious code in the U-Boot ext2fs.c/ext2fs_read_inode(): inodes_per_block = EXT2_BLOCK_SIZE (data) / 128; However, when this was replaced by inodes_per_block = EXT2_BLOCK_SIZE (data) / INODE_SIZE(data); ..the 2GB/128 byte inode SD cards booted and the 2GB/256 byte inode SD cards didn't. Obviously there is something else at play which eludes me. I have posted on the http://www.denx.de/wiki/U-Boot mailing list, in the hopes they can shed some light on the subject.

Re: [uClinux-dev] SD card corruption upon reboot and de-power
Tom, My SD card is getting corrupted after issuing the reboot command and de-powering the board. And I must de-power the board to save power. Here is the sequence: 1) From uClinux, issue reboot command 2) Exits uClinux and enters to DEBUG prompt 3) De-power entire board. Not every time, but sometimes the SD card is getting corrupted from this. Does anyone have any advice or know of a better method? Would it be better just to 'umount' the drive, and then de-power, skipping the reboot step? Steve Bennett implemented a uClinux 'poweroff' command that turns the power off on a WildFire board with the RTC option (and no short across the Wakeup pads). It appears to do quite a bit of background work before turning off the power. Perhaps it closes any open files, etc..?

Re: [uClinux-dev] uCLinux and RTAI
Brendon, I am looking at various realtime linux solutions for use in a personal embedded application. I understand that uCLinux is not a RTOS, but I have read posts on the Internet talking about using RATI with uCLinux. In particular I am looking at the Microblaze and Blackfin architectures. I have not found any concrete answers. Is it possible to use RTAI and/or LXRT with uCLinux on these architectures (or any other architectures for that matter)? My understanding is that there are some licensing problems that halted RTAI use. These and other RTAI problems have been addressed by Xenomai (www.*xenomai*.org). There is also Xenomai support for the Blackfin (http://osdir.com/ml/linux.real-time.xenomai.devel/2007-10/msg00114.html).

Re: [uClinux-dev] uCLinux and RTAI
Brendon, Is there any stable realtime support for Microblaze at all using the uClinux-microblaze port (It does not seem like there is for Xenomai, but maybe for RTAI)? A post to the Xenomai list would clarify this. They are very familiar with their RTAI predecessor. I have considered adding a BF DSP to my project which is why I was asking about it, but I currently have an FPGA on the board and would like to try using a Microblaze soft-core first to see if it will achieve what I need before looking at adding the extra chip to the board (BF DSP). As a ball-park figure, allow about 20 to 30K$ to port Xenomai to a new platform. It was estimated at a couple of man-months to port Xenomai to Coldfire/uClinux platforms. The fly in the ointment is that it takes a very smart developer with considerable Xenomai and target platform expertise ..all under the same hat ..and you pay for this.

After going through all of these options carefully (using the existing boards as a template) you can exit this part of the configuration by selecting File?Quit and then saying Yes to save changes. After this dialog disappears another dialog with a bunch of buttons appears for selecting the user applications to include by default in the final image ..such as BusyBox, Network Applications, etc.. Each of these buttons contains lists of applications that can be included by default. Same as before, use the existing Intec board as a template for selecting these applications. You can see the existing configurations for other boards by performing a make xconfig on an existing directory. The trick here is knowing which options to enable and what dependencies there might be. Here is where this uClinux list can be very helpful. There are comments in uClinux.../Vendors/Intec/WildFireMod/Makefile which help you configure this makefile to either build a SD-card image or a flash image. I recommend the flash image because this leaves your SD card exclusively for datalogging and data storage. Once you think the kernel is configured the way you want, enter make and your PC will grind away for a long time as it builds the updated linux and romfs images. Forgive me for this very brief summary. If you need more support in the mechanics of configuring and building your kernel, please contact me directly.

Re: [uClinux-dev] ( subshell ) | telnet --not workingon WildFireucLinux
Hi Tom, No telneting isn't a problem if I do it manually. And I can run other multi-line scripts just fine. How about sleep? Is the problem as Jamie mentioned that busybox-msh telnet cannot be used with input from a pipe? To list at large: Is there a way around this? The board I was using before that could run the telnet subshell script was the Atmel NGW100. I have a few of them here and it seems all have failed one way or another. I was able to get one to boot long enough to get the following info about the kernel used: Board: Atmel NGW100 Image Name: Linux-2.6.18-atngw Image Type: AVR32 Linux Kernel Image (gzip compressed) Data Size:912607 Bytes = 891.2 kB Regrettably, this not tell us how its Linux was configured. It does not tell us what services were enabled/disabled. However.. If you have the source tree, you should be able to run make xconfig to get a blow by blow description of your Linux-2.6.18-atngw's configuration. To be on the safe side, run make xconfig on a copy of your source tree.

In fact, I know little about scripting. And I do not have access to a uClinux board right now. However, I do know that the uClinux loaded on the WildFireMod happily executes scripts. On startup it executes /etc/rc. If you have uClinux loaded in flash, try running prep-sdcard.sh which will partition a SD card and echo its progress. And I need the last line to tell where to telnet to. When I telnet in manually, I can do it successfully with or without the port number (23) at the end. So, telnetting is NOT a problem? To answer you question, it seems nothing works in the subshell. I tried putting sleep 1000; in there and it still took about a half second to return the prompt, with no error reported. So, sleep may be the problem? Also thought it may just be telneting in really fast, so I put in a command to cp a file that exits on the remote server to a new filename, but it didn't work, so I don't think it's telneting or sleeping. I don't see anything printed to the console, so I don't think echo is working in the subshell either. ..yet etc/rc merrily echos every time you boot uClinux... For example, say I call my scrip t-net, here's what my session looks like: # ./t-net # only after about 1/2 second or so after entering 't-net' Forgive my ignorance, but, could the bracketed script be part of the problem? Can you test a couple of conventional multi-line scripts? On a different uClinux system I could watch the whole telnet session in real time on the console as the script ran. What shell was it running? Do you have access to its uClinux configuration? What shell does it use? What services are enabled/disabled?

The key concept here is if in doubt leave out ..or leave it as it is. After going through all of these options carefully (using the existing boards as a template) you can exit this part of the configuration by selecting File?Quit and then saying Yes to save changes. After this dialog disappears another dialog with a bunch of buttons appears for selecting the user applications to include by default in the final image ..such as BusyBox, Network Applications, etc.. Each of these buttons contains lists of applications that can be included by default. Same as before, use the existing Intec board as a template for selecting these applications. You can see the existing configurations for other boards by performing a make xconfig on an existing directory. The trick here is knowing which options to enable and what dependencies there might be. Here is where this uClinux list can be very helpful. There are comments in uClinux.../Vendors/Intec/WildFireMod/Makefile which help you configure this makefile to either build a SD-card image or a flash image. I recommend the flash image because this leaves your SD card exclusively for datalogging and data storage. Once you think the kernel is configured the way you want, enter make and your PC will grind away for a long time as it builds the updated linux and romfs images. Forgive me for this very brief summary. If you need more support in the mechanics of configuring and building your kernel, please contact me directly. But, if you need support figuring out what services to include and how to configure them, this list could be very helpful.

May I ask what kind of storage and bandwidth we are talking about? Would it help to have a couple of mirror sites? If so, any thoughts as to the capabilities required of these sites? When you mention the desire for additional bandwidth, can I ask what exactly are you referring to? Dreaming in Technicolor, what would you like to see?

Howdy Claude, For some months ago I have noticed that there are periods of time in which accessing to uClinux web site is slow and often impossible. Is there any problem with the uClinux site server? Well, maybe the reason is that, since uClinux is a fantastic creation, there are more and more developers that are discovering it and, thus, overloading the website to download the code. In that case, if there is any developer that has taken profit of uClinux and owns a web hosting business, please donate some servers to uClinux.org!!! :-) Donation to increase bandwidth for the project are always welcome. We have paid for additional bandwidth with iPower in the past to off load some uClinux-dist traffic but iPower shut down all large file transfers as our bandwidth use was being reported as impacting other users of there webservers. That was a sad day! Turns out several users in China and in Europe had been using aggressive transfer methods and resulted in a denial of service for iPower perhaps? I am not sure as iPower was not helpful in resolving the issue. Their solution was to just disable our account. Again .. very sad. To those who are already donating time, servers and band width: our thanks goes to Analog Devices, Arcturus Networks Inc. and Secure Computing (SnapGear). So if anyone knows of others who are willing to provide addition bandwidth for the large file transfers please drop me an email [EMAIL PROTECTED] or give me a call at (416) 621 0125 Cheers, Michael [EMAIL PROTECTED] Cheers.

Re: [uClinux-dev] Coldfire 5282 - suitable?
Hi Allon, You might want to consider posting on the WildRice user list which is the unofficial Coldfire list: [EMAIL PROTECTED] Join the list. [EMAIL PROTECTED]Join the list in digest mode. [EMAIL PROTECTED] Send a post to the list. [EMAIL PROTECTED] Leave the list. We're planning a new design for what amounts to a data bridge between ethernet and a 32 bit memory mapped device. This is in a battery-powered device, so low power consumption is critical. The 5282 seems like a reasonable choice; it's pretty mature, though, and I was wondering if anyone might be in the know, or have opinions on its suitability for a new design, and maybe what alternatives might be good to consider. May I suggest the MCF5208 with 1.8v DDR and Flash. It does not do very much, but it does it very quickly and it draws a fraction of the power consumed by the MCF5282. You can get a M5208EVBe evaluation board for little more than the cost of the USB-BDM pod included in the kit. I believe it is available through major distributors and even DigiKey. Just make sure you get the M5208EVBe and not the M5208EVB (sans 'e') which is older and consumes more power. If you could talk to your 32bit mm device with only 16 bits, you could just copy and paste the M5208EVBe into your product.

[uClinux-dev] Real-Time uClinux/ColdFire
Is anyone interested? There are dozens of ways to add real-time capabilities to Linux based systems (http://www.linuxdevices.com/articles/AT8073314981.html). Xenomai (http://en.wikipedia.org/wiki/Xenomai) is, arguably, the most appropriate. Xenomai has been successfully ported to the Blackfin/uClinux. There is no doubt this this could be done for the ColdFire. But, first, we must find out if there is any interest in such an initiative. Can we have a straw poll? 1. Would a Xenomai/ColdFire/uClinux port be of any use to you? 2. How many hours per month would you consider contributing to maintaining such a port? 3. How much money would you consider contibuting to the initiative? 4. Would you consider contibuting to the initiative in any other way? Time? Expertise?

RE: [uClinux-dev] Calling all M5208EVB Kit owners.
Hi Shantur, Great initiative! Count me in. I am not very helpful when it comes to uClinux, so I would have no idea how to catch and handle interrupts triggered by the MC13192 under uClinux. But I can certainly help with the low level s/w that talks to the h/w, having done it. As a start, aside from handling interrupts, it should be very simple to port put the DemoSMAC_host and DemoSMAC_remote dBUG demo programs to run under uClinux. We could also throw in the library functions that support these [dBUG] demos. Of course, receiveing and transmitting messages is a long way from ZibBee ..but it is a start.

RE: [uClinux-dev] RE: page_offset.h incorrect for M5208EVB
While I'm not familiar with the 5208, isn't dBUG in Flash, not SDRAM? Once it stops running (by passing control to Linux) then any RAM it was using should be fair game, provided that all its hooks (interrupt vectors etc) are removed (which they should be). My first reaction was Duh! Why didn't I ever question this. I believe that amongst other things, the dBUG stack is near the bottom of SDRAM. So, it becomes a bit of a philosophical question: What do we want to happen when uClinux is shut down? Return to the dBUG prompt? Perhaps if uClinux could trigger a soft reset on exit, this would result in dBUG booting without the need of values/context stored in SDRAM from prior to booting uClinux.
