This is the normal configuration for building METRO M4 code.

---help---
|
|
During early bring-up, it is safer to execute entirely from
|
|
SRAM until you are confident in the initialization logic.
|
|
Then you can safely switch to FLASH.
|
|
|
|
REVISIT: This auto-selects CONFIG_BOOT_RUNFROMISRAM but I have
|
|
found, with some difficulty, that that choice still defaults to
|
|
CONFIG_BOOT_RUNFROMFLASH, causing link-time failures when running
|
|
from SRAM.

---help---
|
|
According to the schematic, a 32.768 KHz crystal is installed on
|
|
board. However, I have been unable to use this crystal and thought
|
|
perhaps it is missing or defective on my board (there is a metal
|
|
package that could be a crystal on board, but I am not certain).
|
|
Another, more likely option is that there is a coding error on my
|
|
part that prevents the 32.768 KHz crystal from usable(?)
|
|
|
|
The configuration defaults to using the always-on OSCULP32 as the
|
|
slow clock source. This option will select instead XOSC32 as the
|
|
slow clock source.
