From 2ec33f9e6a303a729ceb164d34a85563b6e2c1b0 Mon Sep 17 00:00:00 2001 From: Michael Zhilin Date: Fri, 2 Dec 2016 14:41:26 +0000 Subject: Fix serprog on FreeBSD Using serprog on FreeBSD to read an SPI flash (MX25L6406) via an Arduino Nano V3 with flashrom hangs after 5 seconds while reading. The problem is that kernel method "ttydisc_rint" ignores some bytes. It happens due to enabled IEXTEN local flag of termios. TTY cuts a few bytes, Arduino reads 11264 bytes, but flashrom gets only 11244 bytes and waits for the remaining 20 bytes. The fix is simple: turn off the IEXTEN local flag. Tested on Arduino Nano V3 + FreeBSD 12-CURRENT.
