Function Documentation
◆ semihosting_common()
| int semihosting_common | ( | struct target * | target | ) |
Portable implementation of ARM semihosting calls.
Performs the currently pending semihosting operation encoded in target->semihosting.
This is a user defined operation (while user cmds 0x100-0x1ff are possible, only 0x100-0x107 are currently implemented).
Reads the user operation parameters from target, then fires the corresponding target event. When the target callbacks returned, cleans up the command parameter buffer.
Entry On entry, the PARAMETER REGISTER contains a pointer to a two-field data block:
- field 1 Contains a pointer to the bound command parameter string
- field 2 Contains the command parameter string length
Return On exit, the RETURN REGISTER contains the return status.
