I believe this can be fixed by removing making sure the server look does not read the data from the semihosting redirection socket.
--- **[tickets:#414] Semihosting message redirection TCP server gets the input data flushed before it can be used** **Status:** new **Milestone:** 0.11.0 **Labels:** semihosting **Created:** Wed Sep 06, 2023 03:38 PM UTC by Marek Vrbka **Last Updated:** Wed Sep 06, 2023 03:38 PM UTC **Owner:** nobody Consider that the debugged target is repeatedly making READC semihosting call after `arm semihosting_redirect tcp 7777 all` has been run. Target stops on the semihosting call while OpenOCD is waiting for data. We send for 10 bytes at once to the TCP socket. Expected behavior: Data is buffered until target makes 10 READC semihosting calls to read all of it. Actual behavior: Target gets one byte, rest of the data is flushed by `semihosting_service_input_handler()` before it can be used. I suspect the regular READ semihosting call has the same issue. --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
