Other Parts Discussed in Thread: AFE032
Hello,
We are designing a PLC system based on SOMPLC-F28M35. We have used the schematics provided by TI regarding the PLC Modem, but we haven't used the docking station board and, instead, we have used just the coupling circuit (no FT2232HL). We made the programming of the MCU using a JTAG emulator and CCS. After that, we use a host MCU in order to check the functioning of the system sending a message through UART (with the format described in the documentation provided by TI), but we don't see anything at the SPI that connects MCU and AFE032, so it seems the system is not working. Any suggestions to solve the problem? What could be wrong?
Any help would be appreciated.
Best regards,
Joaquin
