Arguments

name_dev

Device name (see Note #1).

p_src

Pointer to source buffer.

...

Pointer to variable that will the receive return error code from this function:

FS_ERR_NONE

Octets written successfully.

FS_ERR_NAME_NULL

Argument name_dev passed a NULL pointer.

FS_ERR_NULL_PTR

Argument p_src passed a NULL pointer.

FS_ERR_DEV_INVALID

Argument name_dev specifies an invalid device.

FS_ERR_DEV_NOT_OPEN

Device is not open.

FS_ERR_DEV_NOT_PRESENT

Device is not present.

FS_ERR_DEV_INVALID_LOW_FMT

Device needs to be low-level formatted.

FS_ERR_DEV_IO

Device I/O error.

FS_ERR_DEV_TIMEOUT

Device timeout.

Returned Value

None.

Notes/Warnings

  1. The device must be a NOR device (e.g., “nor:0:”).
  2. Care should be taken if this function is used while a file system exists on the device, or if the device is low-level formatted. The octet location(s) modified are not validated as being outside any existing file system or low-level format information.
  3. During a program operation, only 1 bits can be changed; a 0 bit cannot be changed to a 1. The application must know that the octets being programmed have not already been programmed.
