Downloading app takes 30-60 seconds at 115200 baud.  Why so slow?

Is debug info (symbols, etc.) include, which can be disabled?

Is the compilation code-space optimized?

Thanks.

As a rule of thumb today, we have found that a 15K application typically takes about 12s to erase the EEPROM and download then verify that it was downloaded successfully. Roughly 80% of this time scales linearly with app size while the rest of the time is used for preparing the chip for download.

Note that we have found a method to improve the download speed and we are working on a solution which will be implemented in the next revision of the SDK (hopefully before the end of the year).

Once this new method is in place, a 28K download will probably take around 12-15 seconds.
