Running nRF52811 on nRF52832 Development Kit via Soldering nRF52811 chip onto Development Kit

[Ameer Usman]

So I want to run the nRF52811 chip so I removed the nRF52832 chip from its development kit and soldered the nRF52811 chip but I cannot seem to program it. What are the required settings I would be needing to change to make it work, for starters, a simple 'ble_app_beacon' example.

I am using Segger Embedded Studio (SES).

Hi!

The nRF52811 and nRF52832 are pin-to-pin compatible with a slight schematic difference (the 832 has two capacitors extra for P0.25 and P0.26), and programming the nRF52811 on the 832 development kit should work with no changes to the code. 

I suggest you use a multimeter to make sure none of the pins have been shorted during the soldering.

Then measure the voltage from the DEC1 to DEC4 pins. Use the product specification for the chip for voltage reference, chapter 7, but really you're just checking that they're not at zero.

Also, could you switch to programming with nrfjprog and make sure to program with the --log flag. This way, it's easier to see what's going wrong. 

Best regards,

Heidi

I think there are some changes to be done in the preprocessor or linker to make the PCA10040 softwares to work on the nRF52811 as the program is with the make settings of the nRF52832. But I am not sure which settings need to be altered.
