CC3235MODSF: Need help in programming the custom board

Part Number: CC3235MODSF
Other Parts Discussed in Thread: UNIFLASH

Hi,

I have removed the all the jumpers from CC3235MODSF LaunchPad and then I programmed the cc3235 module by connecting the FTDI programmer.

FTDI RX -> CC3235MODSF TX

FTDI TX -> CC3235MODSF RX

SOP2 -> Pull up

I have programmed successfully using the uniflash. while programming I have selected CC3235MODSF Serial.

Then I have design the custom board. I have attached the schematic file below. I have connected the FTDI (USB to Serial converter). but this time uniflash throws the error. I am not able to program. It seems like the the module did not send any ACK signal to uniflash.

Is there anything I missed? I bought the Module from DigiKey. Does the chip loaded with serial boot loader?

Please help me to resolve this issue.

Regards,

Sundar

Sundaresan,

On your schematic, GPIO1 (UART_TX) is connected to FTDI_TX and GPIO2 (UART_RX) is connected to FTDI_RX. Is this correct?

Hi Seong,

Thanks for the help. I am able to upload the program successfully in the custom board.

I have fetched the out of box code into the module and power up the module.

Now the module continuously restarts and after few minutes it says the error below.

[ota report task] Error openning socket, -2017

I have attached the video. Please advice me what went wrong.

Launchpad is working fine with the same code. Only custom board restarts.
