Problem flashing BETA-Firmware <solved>

Hi,

i was just trying to update current FW to be able to use the closed-loop PWM Idle control.

Followed the MS2-Extra Manual but run into problems with the Timed out reading response - Error. Tried another laptop with WIN95 and REAL Com-Port, no joy.

Found a hint to proceed as follows:
First use FW-Downloader or command-line to load bootstrap.s19, e.g.
C:\Program Files\MegaSquirt\MS2_Extra_Firmware\ms2extra_beta20071104>ms2dl.exe -
r 115200 -c 4 -j bootstrap.s19 (-c Parameter to set correct Com-Port, for this was COM4 due to USB->RS232 Adapter)

Bootjumper must be set!

Thereafter Remove Bootjumper and upload Firmware:
C:\Program Files\MegaSquirt\MS2_Extra_Firmware\ms2extra_beta20071104>ms2dl.exe -
r 115200 -c 4 -j ms2_extra.s19

This did the trick!

Hope this explicit hint will help others. Im pretty shure this was mentioned somewhere "officially", but i was not able to find it in the MS2-Extra-Manuals...

best regards
Carsten

If you just use the downloader batch file that comes with the firmware, and follow the instructions on the screen, it should just install no problem.

just looked into the mentioned .bat-file. ok, obviously this one should have worked as well, but im not shure if i had used the option "coming from MS2-standard" (maybe during the runs after the first unsuccessful one.. ) as i had 1.0.2 on my MS and thought this would be a non-standard-version as well.

best regards
