Programming error

[Stanley]

Hi, dear support team, I program the softdevice(S110,v7.1.0) to the nRF51822 devices(our product) by nRFgo Studio v1.21.1.3.

The nRFgo Studio shows a error message as below.

Only one piece 100% failed and others are normal.

What it means?

Thank you so much.

Hi Stanley,

Could you confirm, you have several custom boards (same layout) and on only one board you see the issue ? Could you check if you have the same error with nrfjprog and try "nrfjprog --recover" and then try to flash the softdevice with "nrfjprog --program" .

If you simply flash an application without softdevice such as the blinky example, do you have the same issue ?

Hi Hung Bui,

Thank you for the information.

Yes, I have several custom boards and I see the issue on only one board.

I have tried the command "nrfjprog --recover" and "nrfjprog --program", it seems normal.

I have the same issue if I just flash the application with softdevice. The nRFgo Studio still popup the error dialog.

There are some messages for your reference. Thank you so much.

So what you are telling is that the board was programmed and worked well if you use nrfjprog to program but it's not possible to program if you use nRFGo Studio ? Does the application work after you flash with nrfjprog ?

Have you tried to call nrfjprog --verify to check if the hex is match ?

Hi Hung Bui,

Actually, My board was programmed well but it doesn't work.

I guess the ROM of nRF51822 was broken, right?

I have tried to call nrfjprog --verify, It shows "verify failed".

Let me show you the log below.

Thanks!!

Has the board worked before ? Seems like an issue with the internal flash on the chip.

[Stanley]

Yes, the board has worked before. If it's possible, may I ship the board to Nordic for analysis?
