Thread CLI not working in BC840DK

[Sunil vignesh]

Hi I am testing the Thread examples

I worked on SIMPLE_COAP_EXAMPLE in nrf52840 DK there it works fine while opening UART and enter to CLI commands and its working

but i have implement same code to the board BC840DK where the uart pins are P1.01,P1.02 (RX,TX)

I can doubt that due to uart pin change the cli doesn't work for bc840dk but i don't know where to config the cli uart lines

Hi,

The UART pins are hardcoded in the OpenThread libraries. To change the UART pins, you need to rebuild the libraries according to the instructions in Building the latest OpenThread libraries.

The pins must be configured in transport-config.h.

Best regards,

Hi,

For nRF5 SDK for T&Z v4.0.0, the UART pin config is located in the file platform-config.h.

The libraries needs to be recompiled for each board unfortunately, it is not possible to configure UART pins in the board headers in nRF5 SDK. For nRF Connect SDK, the OpenThread source files are (if configured) built for each project, which means that it can get the UART pin config directly from the build/configuration system.

Best regards,
Jørgen

Openthread stores some persistant data in memory, see OpenThread memory layout and requirements, Like Thread commissioning data etc.

Ok but every power rest it doesn't over write on same address it extend memory

I need to add some data in flash storage so i have tried to implement flash fstorage here.

i receive error like

You need to define a section to use for fstorage. Try looking at the example in the SDK. i.e. nRF5_SDK_17.0.2_d674dde\examples\peripheral\flash_fstorage

/* Create the section "fs_data". */
NRF_SECTION_DEF(fs_data, nrf_fstorage_t);

This also have to be added to the section placement file.
