Hardware: am3352 2.1Rev
Description:
Spi slave dma can not been trigger by hardware event(EDMA3EnableTransfer(SOC_EDMA30CC_0_REGS, chNum, EDMA3_TRIG_MODE_EVENT);).
But I use manual trigger, I can start dma and send and receive one word data; and then the dma stoped; At this time, I go on set event by manual trigger, Spi slave will send and receive another word.
You know， what I need is transmit data continuously without any interruption by spi slave dma。
But When I use spi master dma, I never find this problem. I have tried several ways to test spi slave dma, I think maybe there is something wrong with TI SPI slave dma.
I sincerely hope you could help me as soon as possible.
