example i2s_dma:
num = bflb_dma_channel_lli_reload(dma0_ch0, tx_llipool, 1, tx_transfers, 1);
bflb_dma_channel_lli_link_head(dma0_ch0, tx_llipool, num);
num = bflb_dma_channel_lli_reload(dma0_ch1, rx_llipool, 1, rx_transfers, 1);
bflb_dma_channel_lli_link_head(dma0_ch1, tx_llipool, num);
也有这个问题,rx也用tx_llipool,你们肯定没测试过!这个sdk问题太多! |
