Set this option to route lp_core_printf to the console HP-UART.
|
||||
This allows you to easily view print outputs from the LP core, without
|
||||
having to connect to the LP-UART. This option comes with the following
|
||||
limitations:
|
||||
|
||||
1. There is no mutual exclusion between the HP-Core and the LP-Core accessing
|
||||
the HP-UART, which means that if both cores are logging heavily the output
|
||||
strings might get mangled together.
|
||||
2. The HP-UART can only work while the HP-Core is running, which means that
|
||||
if the HP-Core is in deep sleep, the LP-Core will not be able to print to the
|
||||
console HP-UART.
|
||||
|
||||
Due to these limitations it is only recommended to use this option for easy debugging.
|
||||
For more serious use-cases you should use the LP-UART.
