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.

neither using ncs1.5.0 nor using ncs1.5.1 ,peripheral_uart sample uart code is the same .i use nrf5340dk and ncs1.5.1 ,encount this situation and spending several days to resolve,but have no result . you show three same code,do not understand what's your meaning.

I have re-unzip my ncs1.5.0(former run well), sample peripheral_uart code i do not change a char, but when debug ,log information pop out "Not able to allocate UART receive buffer". maybe i should re-mount may computer operating system???

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?
