[sivaguru]

how to compile openthread library files for nrf52833, 

i followed the procedure as below

1. start with a fresh copy of the SDK, and make sure you place it as close to the ROOT of the hard drive as possible.
2. Open a command line and go to [nRF5 SDK for Thread and Zigbee v4.1.0 ROOT]\external\openthread\project.
3. Enter the following commands:
4. git clone github.com/.../openthread.git

b.cdopenthread

c.git checkout c6a258e3a5bd90aa26d8245c435c0ae5797027f4

4. Modify the UART pin config in [nRF5 SDK for Thread and Zigbee v4.1.0 ROOT]\external\openthread\project\openthread\examples\platforms\nrf528xx\nrf52833\transport-config.h per your requirements.
5. Go back to [nRF5 SDK for Thread and Zigbee v4.1.0 ROOT]\external\openthread\project and run "py -3 build_gcc_libs.py" from the command line.
6. When that is done, run "py -3 import_libs.py gcc" from the command line.

for nrf52833 , but found only nrf52840 get compiled
