Not able to allocate UART receive buffer

[zhouhaifang]

  I use our designed board with control chip nrf5340  to test ncs1.5.0 sample peripheral_uart , I not changed a word of sample .but when debug program, show :Not able to allocate UART receive buffer.   this buffer is only 20 bytes length!!!! .our board can load /debug ,but when debug ncs1.5.0 example peripheral_uart ,alway error . is our board supply voltage error or design error???, or soft may have some configure i do not configure??? using nrf5340dk debug will not produce these error.

Have you followed the guide her for testing; https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/peripheral_uart/README.html#testing 


What terminal are you using?

It works for me, i have tested on a nrf5340 DK v0.11.0


Could you try to du a update of the NCS repository?

Using the "west update" command?
