Hi everybody!
I have a Simpad SL4 and I installed the Ångström Distribution with opie on it. I want to install more software like a webbrowser, but there is not much space left on the flash memory. I found on opensimpad.org that it is possible to upgrade the flash. Is there anybody who has upgraded the simpad to 64 MB flash? Does it work? Where can I get a compatible flash chip for my simpad to upgrade it? burn |

Update:
Conrad could not make me an offer for the chips, but I found them at digikey [1] for 23,79 € for one chip and I ordered and got them! :-) Next step is to remove the old flash chips. This could be very difficult for me, but I will try it! I'll report when it's done. burn [1] http://de.digikey.com |

Hey everybody,
I did it!!  This weekend I upgraded my Simpad to 32 MB flash. You will find a (german) report and pictures on my blog. But now, after installing the Siemens Bootloader with the JTAG tool, I've a problem with upgrading the bootloader. After powering on the simpad, the serial console shows that: CODE PBL V2.4 20.07.2001 Booting internal PBL image... ================================================ Siemens Switzerland Bootloader V2.4 20.07.2001 Running @206Mhz Processor ID 0x6901b118 Press ESC for monitor Occupied Memory: [0x00004000-0x00008000],[0x01f00014-0x01f74b9c] No 16Bit Flash detected No 32Bit Flash detected 0x00000000 FlashImage Checksum 0x05040014-0x05061ab0=0xffff7959 Image Update, Old Image unc hecked Fabdata Flash @0x05040014 Ram @0x01f21ab4 Init Fabdata... Done [/ ] The slash is turning round, but nothing else happens. I can't upgrade the bootloader with serload. Has anybody an idea what I've to do? burn |

Hey,
I think I was a little confused. I would upgrade the flash to 64 MB not to 32 MB. So something other must be wrong  At this time: Upgrade failed. But I don't give up! So long, burn |

Hi, you can flash this [1] hh.org bootldr. You are right in your blog the jtag tools are only capable to recognize one chip. urjtag [2] can use both chips. the hh.org loader has hardcoded addresses to use the second chip. so you may not be able to use bootldr to flash an image but you shuld be able to boot a kernel from an cf card. or flash the image with urjtag. but it may be neccessary to update the adresses in bootldr an kernel.
best regards nice btw. because of university stuff i am not able to read the forum frequently. but i can try to help a bit but cannot promise 1 http://opensimpad.org/images/b/b7/Test_bootldr.img 2 http://urjtag.org/ |
