Hi ,
We have designed the custom board using DA14531 SOC and observed some issues while programming the board. I can able to detect the SOC but failing when i try to program it with smart snipet tool box. Please find the below screenshot for your reference.
Device is detecting.
please suggest.
Thanks in advance

Hi Pavan,Thank you for posting your question on our Online Engineering Community.From the Schematic you have shared I can see that you are using the correct (default) SPI pins for the Flash and the correct (P0_2 and P0_10) pins for the SWD interface. Since it is a custom board, I suppose that you are working with J-link probes?Could you try to hook your custom board SWD pins with the SWD pins on the Dev Kit?Please refer here: 19. Serial Wire Debug Probe — DA145XX Tutorial SDK Getting started (renesas.com)Try to connect and program your board via the J-Link available on the Dev Kit and share your feedback.Kind Regards,OV_Renesas
Thanks for your answer , I tried with the Devkit Jlink but issue still the same, not able to detect the device.
Please suggest.
Hi Pavan,Thank you for the reply.From the Log Window I can see that the DevKit J-link is able to connect to the device. Please go on the Flash Code tab and try to press the Connect button. Have you burned anything in the OTP header?You could also try with the Dialog SmartBond Flash Programmer since you are able to see the JTAG ID and try to burn the Flash from there.Kind Regards,OV_Renesas
I have not burned anything on OTP header , I tried with smart bond flash programmer also but its not flashing and also same is on smartsnippet tool,. Please find the below screenshot.
Hi Pavan,Thank you for the reply.Were you able to program this board in the past? Is there any active firmware inside the board?Kind Regards,OV_Renesas
Its completely new board , Programming it for first time. Attached design files, We had connected vbat_low pin to 3.3V source previously, now we have cut that track.
Please suggest

Hi,
Waiting for your reply.

Hi Pavan,Thank you for the reply.So, you are not able to access the custom board by SWD or 1-Wire UART ?Are you able to download any FW into the RAM via Keil IDE?Also on P0_10 and P0_2 which are the SWD interface you have added the R5 and R3 resistors, which is their value and why did you add them?Another approach, would be to remove all the peripherals (not the SPI Flash) and try to see if you are able to access the board.Also where is TP1 which P0_5 is connected to?Kind Regards,OV_Renesas
- Yes i can be able to download the firmware via Keil into the RAM, cannot debug.
- R5 and R3 are 0E resistors just shorted.
- TP1 is unused we are not using.
