Part Number: TMS320F28335
Hi experts,
My customer using MCBSP as SPI salve. When they use interrupt to transfer/receive data, it works fine.
(green:clk red: master out, blue, slave out)
However, when they use DMA, only the first few data is received and no data is transferred.
They take Example_2833xMcBSP_DLB_DMA as reference to add dma. also, the project works normally using loopback. This issue only happens when using a external master.
Any idea what might be the issue here?
Regards,
Hang.
