Hardware 2.0
The new electronics is based on the new TMS320C6657 DSP from TI. Communication between the PC and the electronics is based on a Gigabit Ethernet connection.
It is expected that the PC is running the 64bit Version of Windows 7.
In the standard configuation the software running on the DSP board is loaded from the PC after startup of the electronics. It is therefore necessary to install a TFTP Server on the PC.
In more detail:
Install an Ethernet adapter in the host PC, which is dedicated to communication with the Electronics.
The address of this adapter has to be 192.168.1.2. Subnet Mask: 255.255.255.0 Gateway 192.168.1.1
A suitable TFTP Server is TFTPD64. A suitable *.ini file will be supplied as below:
The name of the downloaded file is C6657le.bin
Start the TFTP server first, then start the electronics. There should be an Gigabit ethernet switch between the electronics and the PC.
After loading the *.bin file a message is displayed in the TFTP server window. The download and startup can take up to 1min.
After booting successfully the new electronics appears with address 192.168.1.102. It should respond to the "ping" command. Now you may start the PSTMAFM program on the PC. Please select HW_platform 5: C6657 in the Initialization form, save and restart the program.
To change the IP address from the default value of 192.168.1.102:
- In Initialization change the IP address and press Save to Flash button.
- Afterwards quit the STM Program.
- Change the IP Adress of the network card.
- If you changed the subnet, please change the corresponding parameters in the TFTP Server.
- Reboot the DSP (turn off, wait 5s, turn on).
- Upon software restart the DSP will appear under the new address.
