* @brief Configuration of default stack sizes
|

|

|
|
* printf takes a pretty tortured route through the C lib
|
||
|
|
* then via UHI syscall exception to end up at the UART
|
||
|
|
* driver.
|
||
|
|
*
|
||
|
|
* When debugging timer code we get printfs on the idle threads
|
||
|
|
* stack which can easily blow its limits.
|
||
|
|
*
|
||
|
|
* Note code must be compiled at -Os with these values, using -O0
|
||
|
|
* you'll overflow these stacks.
|
||
|
|
*
|
||
|
|
* NO ISR stack is in use yet, interrupt use the current running stack
|
||
|
|
* hence the big-ish default stack size.
