Hi, I have integrated the Ethos U55 driver unit tests for 128MAC configuration as provided under ethos-u-core-platform-24.11\ethos-u-core-platform-24.11\applications\driver_unit_testsWhen I run the tests, I see that the IRQ tests are passing, whereas the conv test gets stuck. I have checked the NPU status and it seems to be busy/stuck. Below are the debug logs

I figured out that the problem lies with the NPU_OP_DMA_START command. It could mean that the DMA configuration commands executed prior to this are incorrect, specifically
