NATIVE-DECLARATION generated by embedded coder wrong

Created example matlab model to generate code with embeded code and Autosar

i see there is problem in generated arxml

<SW-BASE-TYPE UUID="8033285f-ff92-5e61-6ff2-b4aad944c02c">
    <SHORT-NAME>uint8</SHORT-NAME>
    <CATEGORY>FIXED_LENGTH</CATEGORY>
    <BASE-TYPE-SIZE>8</BASE-TYPE-SIZE>
    <BASE-TYPE-ENCODING>NONE</BASE-TYPE-ENCODING>
    <NATIVE-DECLARATION>uint8</NATIVE-DECLARATION>
</SW-BASE-TYPE>

The <NATIVE-DECLARATION> suppose to be 'unsigned char' but it's generated as uint8

Is there a solution to generate the actula native type ?

Hi,

I would like to follow-up on this question, in case someone else stumbles upon the same issue.

For the <NATIVE-DECLARATION> Simulink uses the AUTOSAR platform types, as they are defined in the AUTOSAR standard. This is mentioned in the following documentation page,

https://de.mathworks.com/help/autosar/ug/automatic-autosar-data-type-generation.html

Please note that these types are used in the generated code and are in turn defined in the header-file Platform_Types.h.

In case you wish to customize the <NATIVE-DECLARATION> data types, then the RTE generator that is used should provide its own header-file Platform_Types.h with the necessary type definitions based on the specific target, since the header-file Platform_Types.h file that is by default provided in Simulink is a stub file intended only for SIL testing.

I hope that this information helps.

Kind regards,

Andreas

You can change the native declaration under the XML options in the AUTOSAR dictionary:
