Summary of change:
Peugeot 106 S16 (1,6 16V) Rotrex c30 84 conversion. VemsTune 1.3.1 / 1.4.9 Vems V3.3 PnP for Peugeot 106 GTI (dp-engineering) Serial Number 1869 Vems Firmware 1.1.97 / updated last year from 1.1.64 VemsTune runs in VMware Fusion /Parallels on MacbookPro ---- Planned: VEMS Upgrade EGT, removable SD-Card, Knock-Sensor ---- 2014 My Firmware AND Bootloader Problems are solved. I build a bsd cable and rent an old laptop with parallel port. Then I've tried to flash with avrdude and got the failure message "Device signature = 0xffffff" ... "Invalid device signature". But with the parameter -F it was possible to overwrite the check and the upload and validate worked well! The vems now knows the serialnumber (yeah!) again and I was able upload the firmware i used at last by serial connection. AND most important: All settings and so on stay there after powering off! Thanks to Marcell for Support! http://www.s16.de/vems/parallel.jpg ---- 2013 At the moment I have a serious problem with my Vems. The car ran fine but recently after a short trip (note: NOT after an attempted firmware upgrade) I could not start it anymore. After connecting the Vems to the laptop i got the following error message: "Boot mode detected." (Choose Stay for firmware upload ....) *1) In 'stay'-Mode I uploaded the firmware 1.1.97 (and lateron other version) again. The upload process seems to be normal. (He's copying 4xx Pages) but the following validation fails. *2) The Vems do not show the real SerialNumber which is n001869 *3) I found some other hints from Jorgen in the Vems Support Forum which I've tried using megatune / megaloader http://www.vemssupport.com/forum/index.php?topic=1421.0 Again I got validation problems error at page: 0 too many errors, bailing out *4) Directly after the failed validation the connection to the Vems is normal. '''It's possible to upload configs and even the engine starts (in some kind of security mode)'''. * But after switching the power off and on the boot mode error appears again. * from this it seems that the bootloader part is partially damaged ** although capacitive coupling can also cause "loopback" situation resulting in the bootloader getting stuck waiting for fw-upload instructions ** together with the damaged serialnumber and the failed verification the symptoms suggest bootloader area was somehow damaged... ** possible solutions. Just ISP, or replace microcontroller and ISP, or mainboard replacement. These guys seem to have had a similar problem (but they experienced it after attempted fw upgrade) http://www.vemssupport.com/forum//index.php?topic=1639.0 http://www.vems.hu/wiki/index.php?page=MembersPage%2FCocorToyota Both changed the atmega128 to solve the problem. Is it possible to change the atmega128 in Vems PnP from dp? Do I need to upload a special bootloader by using spi afterward and is there other stuff I need to do after the change? (never used spi before) Any other Idea? Thanks in advance!
