TDA4VM: Bus error

Hafiz Muhammad Owais

Part Number: TDA4VM

Hi TI,

I have recently tried to run the custom kernel on the A72_0 as I have previously tested my custom kernel on the DSP1 and DSP2 successfully.

While running my custom kernel, I receive the following error : Bus error , as my application crashes immediately. What does this error represents and how to resolve it?

With best regards,

Hi Owais,

Please check your code, it might be accessing some invalid memory.

Hi Brijesh,

How to check this issue? Moreover, why at the target kernel tivxGetSelfCpuId(); is DSP2? where it receives the value? Although I have set the value to the node is A72_0 at vxSetNodeTarget.

Well you could connect via CCS and step in the algorithm code and check which exactly statement causing this issue.
