[QUESTION] Is eRPC just support 256 functions?

[thewon86]

Hi All,

I create a interface with more than 300 functions , a request id with 342(0x156) become 86(0x86) in server side. I find the code uint32_t header = (kBasicCodecVersion << 24u) | ((service & 0xffu) << 16u) | ((request & 0xffu) << 8u) | ((uint32_t)type & 0xffu); , that make the request value (0-255)

So, how could i add more than 256 functions? Adding more interfaces(services)? or modify the code upside?

Thanks.

Hi @thewon86 , yes currently it is 256 function types per interface. https://github.com/EmbeddedRPC/erpc/blob/d8f6a20d7ca4379d1f0ea437714a96b135a7057b/erpc_c/infra/erpc_basic_codec.cpp#L32 You would have to split functions into more interfaces, or write own basic codec with supporting more functions. Anyway we should add some asserts to catch this type of errors in debug mode.

I see . Thank you.
