hal_lld_init()

void hal_lld_init

(

void

)

Low level HAL driver initialization.

Todo:

Use a macro to define the system clock frequency.

@notapi

Definition at line 97 of file hal_lld.c.

                        {
    // Enable DMA
    dmaInit();
}

Here is the call graph for this function:

ke1xf_init()

void ke1xf_init

(

void

)

KE1xF initialization.

Note

All the involved constants come from the file board.h.

This function is meant to be invoked early during the system initialization, it is usually invoked from the file board.c.

Todo:

This function needs to be more generic.
