CCS/IWR6843: Why I can't init the CBUFF on dss?

Tool/software: Code Composer Studio

Hi Ti,

I recently is working on migrating my PPL project（base to lab0020_pplcount_Overhead） to ES2.0 from ES1.0. I can output adc raw data through lvds on es1.0,and all the initiate code about lvds（eg. CBUFF, EDMA,ADCBUF）is on dss project.But when I migrated the same code to ES2.0, the adc raw data can't output through lvds. I checked the CBUFF registers, found that all of the cbuff registers value is zero.Then I checked the return value of invoking CBUFF_init, it is not null, it is success .Why I can success invoke CBUFF_init function, but the cbuff registers wasn't setted?

Hi User,

I've asked an expert to look into this and we should have an answer for you sometime next week.

Hi user,

Does device initialization complete successfully besides the CBUFF initialization? Have you checked to ensure that you are using the function calls correctly with the latest SDK?

Hi Justin,

Thanks for your reply.I can normally use all functions of the board except cbuff, and the same code is OK on es1.0.The SDK version is mmwave_sdk_03_03_00_03.

thanks.

Hi Luomh,

Please see the updated documentation for SDK 3.3.0.3 and ensure that you are correctly following the initialization procedure on the latest SDK.
