Hi all,
I modified i.MX6 platformSDK sample code to playback with I2S audio codec.
sdma\test\spi_lpb.c ecspi_app_test()
sdma\test\uart_loopback.c uart_app_test()
In case of NOT using SDMA, there was no problem to play.
But in case of using SDMA, nothing played(no sound).
It seems SSI asserted DMA request signal and SDMA took exact time to suit data size.
Can anybody help me...?
(Q1) Is there any tips or special settings to use SDMA/mem_2_ssiapp?
(Q2) I set destination address as "SSI Transmit Data Register ： SSIn_STXn". Is it correct?
Thanks.
