custom board for nrf5340

[RHeine]

Hi,

I want to do a custom developpement (custom board) for my project.

I have copied  to a folder on drive D/: the peripherial_uart sample, as well as the folder Board/arm/nrf5340dk...

I modified the CMakeList.txt file by adding "list(APPEND BOARD_ROOT${CMAKE_CURRENT_SOURCE_DIR})"

as described in the webinar "Getting start with custom development in nRF Connect SDK".

But during the build, west will look for the board folder on the drive C:/.

How do I get it to take the file from drive D:/ ?

I try also , as described in zephyr 2.6.99, : " west build -b nrf5340boardv3_cpuapp -- -DBOARD_ROOT=D:\COMMUN\Firmware\accesscontrolsoftware\firmware\trunk\nRF5340DK_Test3\peripheral_uart\boards",

but same result, west go to zephyr_base on C:/.

Best Regards,

Rob.

Hi,

I have some other questions.

I tested the consommation of peripheral_uart, I measured 0.87mA.

What are the ways to reduce this consommation ?

I try to change the interval between the advertising but it do not reduce the consommation.

Now, I will try to use only netcore, I try to modify hci_rpmsg with the peripheral_uart code, but I have some error that I can not resolve for the moment.

I juste include:

#include <bluetooth/gatt.h> in the main.c of hci_rpmsg project.

west gives me this error:

"error: 'CONFIG_BT_MAX_PAIRED' undeclared here"

I try to write CONFIG_BT_MAX_PAIRED=1 in the prj.conf but it do not change nothing.

Is it possible to reduce the consommation if we just use one core ?

Best Regards,

Rob.

That sounds like it should be possible.

Since this is significantly different from the original question, could you open a new ticket for this? It helps with searchability.

Ok, I will make a new ticket.
