I guess I'll need to read over all of the list entries as it's probably mentioned before. But is it possible to boot a kernel that is placed only on the MMC in place of or replacing the one in the MMC itself? I haven't seen this mentioned before, just instructions for loading a new kernel into flash. Unless I missed it. I'm basically trying to avoid doing anything with flash at all in order to minimize the risk of loosing a gumstix (I don't have a working jtag cable yet). Admittedly, I'm guilty of not having done much experimenting in this area yet as I've been busy with hardware issues. - Kim |

Kim, I tested the following for you. I changed the bootcmd via set bootcmd fatload mmc 0 a2000000 uimage\;bootm a2000000 save This appears to me to boot the image on the mmc card. This does erase the flash sector 1 to save the enviorment so I am not sure if it is as safe as you think. Of course you don't have to save the enviorment but typing in the set bootcmd.. every time can be tedious. The image copied to fat always seems to be lowercase filename. David.

Hi david, that's the point to start building a new kernel with samba support. Has anyone already invested time in doing this?

Ok, this is great! I don't mind risking it once, but every time is a bit of a worry. I'll still building a new chassis for my stick so I can't try it yet. But this looks good. Well... I may even be tempted to typing the above command every time until I've verified my new home made jtag cable :) Brilliant! - Kim |

I have had a little bit of time to play with my waysmall computer now. Well boot it up and log in via Hyperterm. So now it's time to start coding stuff. The only problem is that the recommended toolchain looks to be Linux only (not completely unreasonable for a Linux based device). Anyway for reasons that I won't go into here I would prefer to develop for the Gumstix using win2k. Does anyone else on the list develop under Windows. Or does anyone know of any links to websites with any windows based Gumstix development info. Or should I just forget it and dust of that other partition and start upgrading my old red hat 8 installation : ) Thanks in advance, Dan |

I personally would recommend downloading and burning some iso images of Fedora II (http://fedora.redhat.com/download/ or images here for example http://ftp.esat.net/pub/linux/fedora/2/i386/iso/) and go for that. Who knows what problems you could drag up by using such an old linux. Maybe others know whether this is even feasable, but I think it's likely to cause more work than taking the effort to get a more up2date Fedora installed. Just my 2c worth. - Kim |

Hi Dan, haven't looked at the cygwin stuff yet. You have to build the crosscompiler yourself under windows. Currently I'm looking getting usb gadget driver running under windows xp.

I would recommend Fedora II as well. The buildroot package gumstix has put together works great! It will build all the tools and all software.

Thanks for all the feedback. It looks like it going to be much easier doing any Gumstix development under Linux. The 4 Fedora core 2 iso's are whizzing there way to me over the information super highway as I type. In what is probably the first step of my seemingly inevitable migration from Windows to Linux. Apologies for all the questions at the moment, I'll shut up soon. But could anyone recommend a good community Gumstix site. Is there anywhere that shows some of the projects people are working on with their gumstix for example. It'd be really interested in seeing what everyone is getting up to with this handy little piece of kit. I'm supposed to be using mine to develop a kind of interactive bluetooth sign for an Arts project. Initially it will just allow people to request information over bluetooth using their phones or PDA's. The plan is then to expand it to allow people to request film and audio content. I'm sure I'll find other interesting uses for it as well though. Thanks again for the advice, Cheers, Dan P.S. One last question. Does the waysmall case just pop open? I haven't been able to find any references to it on the support site and I don't want to force it or break the case as I might need it later.

Cygwin is merely a wrapper around windows routines. The include files are all different. Unless someone else has gone to the trouble of porting the arm developmental compiler to cygwin so it's available as a package, it's likely to be major work to do that yourself. gcc is of course running on cygwin, but whether or not it has support for arm etc. I doubt it. Somethings compile surprisingly easy on cygwin, but other things would require require more work that it would be worth in this case. There are a lot of dependancies to getting a complete system working for this task I think. - Kim |

Gordon used to build the gumstix images on his windows machine under Cygwin, but I was singularly unable to reproduce his environment in a working way on any machine that I tried. Actually, I couldn't even reproduce it logged in as a 2nd user on the same machine.... So the answer is: it might be possible, but... good luck!

Using "save" in u-boot is really pretty safe. It only unprotects and writes to sector 1, which is where u-boot stores its env vars -- it doesn't overwrite u-boot code at all. Worst case if it were to corrupt sector 1, u-boot will detect this when it CRC's sector 1 before loading the env vars, and it'll just fallback to its compiled-in default vars. At which point a new "save" will just write those out to sector 1 again. I regularly load kernels from MMC w/out writing them to flash by using more or less the process described already in this thread. I also regularly use "loadb" to achieve a similar thing but loading the kernel over serial instead of from an MMC card (a lot slower, but more flexible when I'm working remotely and don't have physical access to the MMC card).
