Hello, I'm working on a custom board, and I use JLink OB as programmer. Whenever I try to connect to nRF52811 on the board, this happens:

I check the connections, everything looks fine, Could It be because of the firmware of my Jlink OB?

Hi,
Whenever I try to connect to nRF52811 on the board
Looking at the screenshot attached, you seem to be using a project that is configured to be used for the nRF52840.
Please try the pca10056e project instead. For the ble_app_blinky project, see the project in the folder SDK_folder\examples\ble_peripheral\ble_app_blinky\pca10056e\s112\ses
You might find the Developing for nRF52811 user guide useful. See this link: infocenter.nordicsemi.com/.../nrf52811_user_guide.html

Unfortunately it is the same as before.
bardia3000 said:Unfortunately it is the same as before.
Are you able to recover the device using nrfjprog ?
nrfjprog --recover
What voltage are you powering the nRF52811 with?

No I can't recover the device.
nRF52811 is powering with 1v8, by the way I checked the programmer, It can program a nrf52832 (powered with 1v8) on another board correctly!
I also tried Segger J-Flash (and I change the programmer device): Here is the result of Log:
Connecting ...

- VTarget = 1.790V
- InitTarget() start
- InitTarget() end
- InitTarget() start
- InitTarget() end
- ERROR: Failed to connect.
Could not establish a connection to target.
and after I changed the speed to auto mode:

I also run "it as administrator" with J-link OB:

By the way, I checked voltage on all pins, It is a bit strange that P0.21/nRST is Low( while I used pull up resistor on it) and also I've never program it, So this GPIO shouldn't be configured as an active-low Reset!
Is it normal for the P0.21/nRST to be Low in this situation?

Sorry Sigurd, Is it possible to answer me?
Hi,
Is it normal for the P0.21/nRST to be Low in this situation?
No, in this situation the pin should not be low.
Do you see this issue on several custom boards, or is it only one board ?
There was a problem about this pin, I solved It, It was connected to another chip, but It can be unsoldered, now the NRST is high, but still the same problem happens, It cannot find the nrf52811.
bardia3000 said:but still the same problem happens, It cannot find the nrf52811.
1) Do you see this issue on several custom boards, or is it only one board ?
2) Could you try to power it at 3V, and see if you are able to program it then ?
3) Also make sure that you have not accidentally switched SWDCLK and SWDIO when connecting the debugger.
1) Yes all borads are the same.
2) No there are some other chips which must be powered with 1v8.
3) I double-checked it, It is okay
