<div>Thanks Mark,</div>
<div> </div>
<div>my first build was using the original sdkconfig.default.hw31, where my ovms3.bin build had I size of 3036096 bytes, quite different to the "reference" ovms3.bin (3.2.002-151-g56116fe) with 2594192 bytes. Then I figured out that the Default setting in the original sdkconfig for 'Compiler Optimization' was 'Default', and I modifed it to 'Release'. Afterwards, I got an ovms3.bin build with 2592512 bytes. This may be more similar to the "reference" ovms3.bin (3.2.002-151-g56116fe) with 2594192 bytes, however, the .bin are not the same.</div>
<div> </div>
<div>I'm used to check builds for equality using md5sum or sha256sum which can't work here due to the different size. Therefore I was asking if there are any more used modifications known from support/sdkconfig.default.hw31, to build exaclty the same "reference" ovms3.bin.</div>
<div> </div>
<div>I'm not sure if this would solve my issue, as there could be some other issue with my toolchain (curently one can't follow the Developer's Guide instructions to get a working toolchain, plz see <a href="https://www.openvehicles.com/node/2263" target="_blank">https://www.openvehicles.com/node/2263</a></div>
<div> </div>
<div>As a start, could you please tell my if you are setting 'Compiler Optimization' also to 'Release' instead of 'Debug' for the automatic builds? If not, there must by some other issue with my toolchain installation.</div>
<div> </div>
<div>Regards, Matthias</div>

<div name="quoted-content">If you copy from support/sdkconfig.default.hw31 to sdkconfig, you should have something pretty close to what we use to build the productions releases.<br/>
<br/>
You may have to accept some default values the next time you build.<br/>
