When I tried to download hex file into aduc845 using Windows Serial Downloader(WSD) version 7.05, an error occur "Download failed with error code 4". I would like to know what kind of error is it and how can I fix it? Is it the port connection problem? I had tried aduc847 as well and the sme problem occur.
I am using windows XP sp2 and I use bluetooth module HC-05 to connect the MCU and computer. Please give me guidelines on how to solve the problem.
