This file defines the Silicon Labs specific mbedtls error code layout and values.
Error code layout.
The standard mbedtls error code layout use the negative space of 16 bits signed integers in order to support all architectures. However the standard mbedtls error code layout is fixed by ARM and does not define a sub-space for additional vendor specific error codes. Additionally the 16 bit requirement is not relevant for the Silicon Labs 32bit MCUs. Therefore Silicon Labs defines a 32 bit signed integer error code layout which does not use the values of the standard mbedtls error code layout given that the 16 most significant bits of standard mbedtls error codes are all ones (which should be the case when running on 32-bit architectures and the application does not strip off the 16 most significant bits):
bit 31: Sign bit. 1 to signify that the value is part of the error code space. 0 for non error codes, in which case all 32 bits are 0 which means OK (i.e. operation succeded). bits 24-30: sub-system id, for example mbedtls, emdrv, etc bits 16-23: module id, for example UART, LCD,... bits 0-15: error code, specific error code
The sub-system id and module id are not allowed to be all ones.
Below is the list of module ids for the mbedtls sub-system. Module specific error codes are defined in the header file of each respective module.Base value for all error codes.
