Hi,
When EVE tries to perform the simple 1-D DMA transfer from external memory to IBUFA after executing TIDL library, the simple 1-D DMA transfer does not work. .
In our case EVE first runs our simple 1-D DMA transfer and it performs well, then EVE runs TIDL and later EVE run our simple 1-D DMA transfer again and it does not work. (the data in external memory is not actually copied to IBUFA on the completion of the simple 1-D DMA transfer)
Our module implemented the simple 1-D DMA transfer by following the source code in eve_sw_01_12_00_00\starterware\examples\edma_simple_eve\src\main.c, which uses register level CSL for edma to setup single 1D -> 1D transfer.
However, the TIDL uses DMA_UTILS to perform auto-increment DMA and somehow it nullifies the later our simple 1-D DMA transfer.
Even we change our 1-D DMA transfer by not using register level CSL APIs but using DMA_UTILS APIs. our 1-D DMA still did not work after running TIDL.
We wonder if there is a universal method to implement our 1-D DMA (moreover, 1D -> 2D, 2D -> 1D DMA) and work well with other coexistent module using DMA such as TIDL?
Mark.
