DMA transfer failure

Postby Lucas_Deutschmann » Thu Oct 12, 2017 9:48 am

Hello everyone,

we are currently trying to implement our depth-estimation algorithm. For now we are using two pre-stored sequences, which we need to access simultaneously.
Running it on solely the ARM processor produces the desired result, but trying to accelerate the function in HW results in an error when executing:

Code: Select all

ERROR: Simple DMA transfer failure accessing address 0x3d400000 : {Decode }


I have confirmed, that the address itself is valid by trying different locations. The error always displays the second address given to the accelerated function. Therefore we assume that the simultaneous access might cause the issue.

The project is based on the "EMC2 Camera Link Demo".

We appreciate any ideas.

Regards,
Lucas
