TI-15.4-STACK-GATEWAY-LINUX-SDK: UART for co-processor, reset issue

Rushabh Shah52

Part Number: TI-15.4-STACK-GATEWAY-LINUX-SDK

I am using cc1310 launchpad as co-processor with raspberry pi connected via UART. Sometimes I get an error "no reset response received after device reset" while running the collector example. Manual reset and restarting program resolves the issue. My guess is soft reset attempt is failing over UART. Request help is resolving this issue.

Hello Rushabh,

I think this has to do with the way linux handles the device port.

Try unounting and remounting.

I am not connecting via USB. I have connected Rx, Tx & Gnd pins between coprocessor & host linux board. Hard reset resolves the issue. I am looking for solution via software for production deployment.

In this case you will need to add the RST pin to the host also and use this to reset the device.
