Hi all, I've tried to implement a simple host-target communication using RTDX based on some examples/tutorials: From the host, I send an integer value to the target. The target reads it and sends it back to the host. The host should then display the value that has been sent back. I've checked my trace LOG and apparently, the target receives the messages that are sent to it and therefore it a...

hello How can I exchange image data between host (MATLAB 7) and target program on C6711 dsk? My hoost and target codes for RTDX are as below this text. When the amount of data to be transfered is more than 1010 Byte, the MATLAB sends timeout error for reading data from 'ochan';although I set the timeout=1000s. Do you know Why? Is it because of para

I am using a C6455 DSK board in a university project in which a DSP application needs to communicate with C/C++ software on a PC in Linux. I have tried RTDX but am having difficulties. I also haven't been able to load the application to the board's Flash memory in order for it to operate independently. 1. Is there an efficient way to load the application to non-volatile memory so that it w...

Andrew- > I don't know about CCS 4, but CCS2.2 in my directory > \ti2\tutorial\evm6201\hostio1 > has what looks like a RTDX interface for communicating with the host. EVM 6201 was back in the day when EVM boards allowed host access to HPI, so my guess is the "hostio1" folder is not RTDX. After DSK 6711, TI starting bring HPI access out to a daughtercard header but not visible to the host

As soon as I switch over to DSP/BIOS, things don't work. If I take the DSP/BIOS application and switch over to regular RT
