Switch Setting for Boot Mode
|
||||
----------------------------
|
||||
|
||||
Boot Mode pins provide means to select the boot mode and options before the
|
||||
device is powered up. After every POR, they are the main source to populate
|
||||
the Boot Parameter Tables.
|
||||
|
||||
The following table shows some common boot modes used on AM62 platform. More
|
||||
details can be found in the Technical Reference Manual:
|
||||
https://www.ti.com/lit/pdf/spruiv7 under the `Boot Mode Pins` section.
