Lock Firmware Flash ROMs: IOCTL_EKF960SI1_FLASH_LOCK
This I/O control request locks the firmware flash ROMs on an I/O controller for exclusive use.
Call:
DeviceIoControl(
handle,
// handle returned by CreateFile
IOCTL_EKF960SI1_FLASH_LOCK,
NULL,
0,
NULL,
0,
&unused,
// pointer to a DWORD variable
pOverlapped
// optional pointer to overlapped buffer (may be NULL)
);
The application may open any port that resides on the corresponding board when calling the
flash ROM lock request. A call of this request should be done before calling any other of the
flash worker routines like erasure or writing to avoid confusion, if several threads try to
update the same board firmware. After the complete firmware update is done a call to
IOCTL_EKF960SI1_FLASH_UNLOCK is necessary.
Unlock Firmware Flash ROMs: IOCTL_EKF960SI1_FLASH_UNLOCK
This I/O control request unlocks the firmware flash ROMs on an I/O controller previously
locked by IOCTL_EKF960SI1_FLASH_LOCK.
Call:
DeviceIoControl(
handle,
// handle returned by CreateFile
IOCTL_EKF960SI1_FLASH_UNLOCK,
NULL,
0,
NULL,
0,
&unused,
// pointer to a DWORD variable
pOverlapped
// optional pointer to overlapped buffer (may be NULL)
);
Write Firmware Flash ROMs: IOCTL_EKF960SI1_FLASH_WRITE
