Hi,
I am trying to us one more SWI with nrf_drv_swi_alloc , but returns NO_MEM => means there is not any free.
I looked to source code, and I find SD_SWI_USED is defined to 0x0000003CuL, that means SWI 2 to 5 are all used.
But looking in the SD specification, for example SWI3 is : "Unused by the SoftDevice and available to the
application."
is it an error ?
Regards,
