Hi,
I am getting errors while programing the otp via otp programmer tool from smart snippets. Following are the error logs. I am using JTAG for programming don't understand what this error suggests. Please guide me through the otp Programming for PAN1740 module.

Thanks and Regards
Thought this might help wit the issue.While using CLI tool i get the following error on the Command prompt
Timeout while waiting to receive the most significant byte of packet length(1000 msecs)
Successfully disconnected from port COM6
OTP Memory burning failed
Thanks and Regards,
Do you attach 6.8V to the VPP pin before you burn OTP ?
Hi Krutarth,
Have you tried burning a daughter board using the pro-kit and Smart Snippets? Also what is the length of your jtag cable connection ?
Thanks MT_dialog
Hi,
Yes I do provide 6.8 volt Vpp before i start burning the OTP and length of my JTAG cable is about 15 cm. I have designed custom interface board and not using any kits for now for the panasonic module.
Hi Krutarth,
Can you try and reduce your jtag cable length to less than 5cm and let us know ? According to panasonic issues for this reason my occur when working with jtag.
Thanks MT_dialog
Alright will try and post the results if problem persists.
Thanks and Regards,
Same problem persists even with 4cm cable . I cannot burn the OTP memory tried CLI tool as well as via smartsnippets. Can read the contents of the memory via smartsnippets.
Thanks and Regards,
Hi, I found the solution to my problem.
Please consider the SWD-JTAG connection recommendations for connecting pull down resistor on SWCLK and pull up resistor on SWDIO lines or it won't work. Panasonic does not mention these anywhere in their design guide nor it is shown in example interface board schematic. It cost me a new interface board design but was finally able to Burn the OTP and OTP-Header. Sharing the link where i found these answer: -

Please close this ticket.
Thanks and Regards,
Hi Krutarth,
Thanks for sharing your foundings.
