Hi There, I have an application that constantly reads/writes to serial. It is written in QT, using QExtSerialPort POSIX library. I send a command and the response ends around 250ms later. But since all commands are different, I don't want to sleep for the worst case (bout 300ms) and then read. Instead I want to keep reading until I hit a '>' character that is always the end of a response. This works fine, I get my responses in about 230ms. However the problem is, when I am using the app on my TS7390, I randomly miss the '>' character. This could happen in 1 minute after starting my app, or it could keep going for say 10 minutes. This results in a loop to infinity waiting for the > character that was supposed to come but never did. My theory is that since I am running of SD, I may be getting those random SD writes that hang the system. Would this cause a character to be dropped and not even get into the serial buffer? I am currently in development stages, so can't move onto NAND just yet. Alternatively I can implement a timeout feature, but my main question here is, with a SD write operation, is it possible for the serial in buffer to reject or drop a character. It's a bit of an annoying problem! Oh yeah, memory, CPU usage of this application isn't a problem. A healty 8% CPU use, with about 14% mem usage. Thanks, Regards, Donal __._,_.___
