TMDSDC3359: Flashing PLC SOM through Serial Communication

Part Number: TMDSDC3359
Other Parts Discussed in Thread: UNIFLASH

Hello,

We've bought a TMDSDC3359 (revD) and we are trying to flash the G3 DC firmware using PLC_setup.sh tool but without sucess.

We have connected the PLC SOM to it's P2 connector and powered the board with the 12VDC source.

Here is the command output:

.#####################################################
# Flashing Data Concentrator with G3 standard

# Script will run the following command:
#   /home/root/PLC/util/dspFu -c /dev/ttyO3 -f /home/root/PLC/G3_DC/sysbios_g3_plc_dc_F2806x_AFE031_CRC16_MSB.sbin

| Suggestions to fix issue:                                 |
| - Verify PLC SOM is securely attached to EVM              |
| - Make sure PLC SOM was pre-flashed with hex image        |

We tried to detect the Zero Configuration GUI using the rs232 on top but still no serial communication.

Please what are the proper steps to flash G3 DC firmware in the PLC SOM ?

BR,

    hi BOUHARA Kamel,

    Which serial port or rs232 port are you using to connect to the PC from the DC ?

    Please try to flash the PLC SOM with the hex image provided in the G3 SDK package using CCS or uniflash.
    www.ti.com/.../ti-plc-g3-dc

    This issue could occur if the device is not preflashed correctly .

    Once the SOM is flashed please try using the Zero config gui to detect the SOM . If this comes up correctly without an error the flashing is done correctly.

    Once done the flash through the serial port should go through.

    Regards.

    We have finally fixed the issue using external SCI-A port with C2Prog.
    The manual delivered in the package is not complete, we don't know if the SOM is already flashed or not...

    Thanks for the short reply anyway.
