Middleware utilities enumerated types¶

group group_utils_enums

Cypress middleware APIs return results of type cy_rslt_t and comprise of three parts:

module base
type
error code

           Module base             Type    Library specific error code
   +------------------------------+------+------------------------------+
   |CY_RSLT_MODULE_MIDDLEWARE_BASE| 0x2  |           Error Code         |
   +------------------------------+------+------------------------------+
             14-bits               2-bits            16-bits

Refer to the macro section of this document for library specific error codes.

Result Format

The data structure cy_rslt_t is part of cy_result.h located in <core_lib/include>

Module base: This base is derived from CY_RSLT_MODULE_MIDDLEWARE_BASE (defined in cy_result.h) and is an offset of the CY_RSLT_MODULE_MIDDLEWARE_BASE The details of the offset and the middleware base are defined below

Type: This type is defined in cy_result.h and can be one of CY_RSLT_TYPE_FATAL, CY_RSLT_TYPE_ERROR, CY_RSLT_TYPE_WARNING or CY_RSLT_TYPE_INFO. AWS library error codes are of type CY_RSLT_TYPE_ERROR

Library specific error code: These error codes are library specific and defined in macro section of the respetcive libraries

Helper macros used for creating the library specific result are provided as part of cy_result.h

Each middleware module has been reserved with 128 error codes
