FXTH870911 module programmed successfully but it is not transmiting any signal.

Hi there,

             I have a FXTH870911 TPMS dev board. Also i have a code provided by NXP. 

The dev board was flashed with the same code earlier by NXP. Later, i just changed one SFR to change my output power from 5dBm to 8dBm. But now TPMS Evaluation board is not transmitting at all.

Steps followed:

• Changed SFR value in Sources>>main.c
• Build all
• here, new S19 file was generated.
• Clicked on flash file to target
• selected programmer as PE Multilink universal.
• Selected proper S19 file
• last step "Erase and program".

here i got following message on console.

After this i checked my TPMS module with signal analyzer, but it is not giving any output. (Earlier it was showing output on signal analyzer).

Please help me out & let me know if there is any step which i missed.

Thanks...

Pritam.

Hi Pritam,

After reprogramming the dev board, have you removed the BDM connector and done a hardware reset (OFF then ON of power supply)?

Best regards,

Tomas

Tomas,

            Thanks for replying. There was some hardware issue. I replaced the microcontroller now it is working fine..

Thanks.
