I have a model that I am attempting to Run in External mode on a F28379D Launch pad. However the mdel contains a look up table that is Row Major so I recieve the following error:

Model 'Exro_Motor_Control' is configured for external mode and row-major code generation, which is not supported.

is there any reasonable work around to this without having to change all my data? I would prefer to have it Row major as that is how the C language is.

Hi Jake,

You can refer the section 'Code Generation by Using Row-Major Algorithm and Array Layout' of the following documentation which talks about Conversion of Layouts from Column-Major to Row-Major for Models with Lookup Table Blocks:

Hope it helps!
