The lowlevel applet initializes the device clock tree: PLLA, CPU clock, Master clock (MCK), ... The targetted frequencies are specific to each device. This applet should be executed only once afer reset, prior to the extram applet.
The lowlevel applet doesn't accept any parameter to be initialized. The only exception is for SAM9X60 devices. In this later case, the list of supported parameters to initialize the applet can be displayed with the following command:
$ sam-ba -p serial -d sam9x60 -a lowlevel:help Syntax: lowlevel:[<preset>] Parameters: preset System clock configuration Examples: lowlevel use default board settings if defined, preset 0 otherwise lowlevel:0 use preset 0 for system clock configuration
Device | Preset | CPU clock (MHz) | Master clock (MHz) |
---|---|---|---|
SAMV71 | N/A | 300 | 150 |
SAM9xx5 | N/A | 399 | 133 |
SAM9X60 | 0 | 600 | 200 |
SAM9X60 | 1 | 500 | 166 |
SAMA5D2 | N/A | 498 | 166 |
SAMA5D3 | N/A | 528 | 133 |
SAMA5D4 | N/A | 600 | 200 |
