◆ esp_xtensa_semihosting()
| int esp_xtensa_semihosting | ( | struct target * | target, |
| int * | retval | ||
| ) |
Checks and processes an ESP Xtensa semihosting request.
This is meant to be called when the target is stopped due to a debug mode entry. If the value 0 is returned then there was nothing to process. A non-zero return value signifies that a request was processed and the target resumed, or an error was encountered, in which case the caller must return immediately.
- Parameters
-
target Pointer to the ESP Xtensa target to process. retval Pointer to a location where the return code will be stored
- Returns
- SEMIHOSTING_HANDLED if a request was processed or SEMIHOSTING_NONE with the proper retval
