Hi, Am using UART in EVMDM642. It has dual UART. I tried out the example, uarttest.pjt given along with DDK version 1.20. It works fine for UART port A which is a 9-pin port. But when I configure the example for UART port B which is a 10-pin port, the example does not work. Serial communication is not taking place if I use UART port B. Has anyone encou

Hi! I'm using DM6437, and finally I can use uart0 with interrupt, but sometimes if I send many messages on com port in short time, uart stops to work completely. I don't see to start interrupt anymore! I assume that it's possible to lost some message on uart, but in this contidion when uart stops to work I have to reset the board to see my application working again.. What can be wrong...

Hello, I am a final year student in the UK trying to get the TMS320C6713 DSP to interface with a touchscreen via a UART connection. I am using the DSK from Spectrum Digital and CCS 3.1. I am using SPRA633C document to get the serial port on the DSK to act like a UART. I have connected pin 36, 42 and 44 and DX1, DR1 and GND respectively on the J3 serial port. These pins connect to a MAX232 chip whi...

First of all thanks for the suggestions. Here are few more observations about the problem. When SDRAM is enabled and refresh is happening, there is no problem with UART until i would't write onto SDRAM. If i read SDRAM. it has no effect. UART works normally. Once I write onto SDRAM, UART gets currupted. If i write less no of bytes, say 10, it
