Unstable OpenOCD #166

Open dvcirilo opened 4 years ago

dvcirilo commented 4 years ago

I've been using my Gapuino (first version) with the plpbridge and the v3.1 release without many communication problems. The system runs on a virtual machine, Ubuntu 18.04. Having recently updated to the last release v3.7.1, and finally using OpenOCD, it's kinda unstable, a lot of "Warn: Burst read timed out" and sometimes it hangs on "Loading binary through JTAG".

Any ideas or debug steps to solve this?

I recently got two GAPuino V2 boards and I have the same issues with the "Warn: Burst read timed out". I get this message multiple times every time I start a program on the board over JTAG. I am using release 3.7.1 with OpenOCD of the SDK as well. But aside from the waring messages it seems to work. At least the programs seem to run on the GAP8 chip.
