I’ve been wrestling with my SL6087 for some time now in terms of getting reliable connections. Regardless of what interface I use (USB->Serial or straight USB) I get sporadic disconnects while trying to program it in Target Management as well as periods when I can’t seem to speak to the module at all. I’m using the dev studio 2.3 and I’m applying the timeout workaround (which involves just unchecking a single box in preferences). Nothing seems to work. It is gotten to the point where I need to do nearly constant hardware resets just to get it to communicate with target management at all. Most of the time I just get a timeout error in developer studio when trying to connect to the module. I’m using the 2.51 version of the firmware and bootloader, but that doesn’t seem to help at all. Is anyone else having these problems? I thought it maybe just a windows connectivity issue so I tried linux and found that I was unable to setup openAT in eclipse there (separate issue and a separate thread). The USB connection used to work better than the serial connection (ie more reliable and consistent connections to download programs and send naked AT commands to), but now the USB connection doesn’t work at all and the serial port barely works.
I can send more information to anyone who thinks they might be able to help me out here - thanks.
