I had trouble on using SPI2 DMA27 . The SPI2 is slave configure connect with Ti AM3358.
I configure the SPI2 working well no DMA .
But I enable DMA27 for receiving, the pREG_DMA27_ADDRSTART register is not the address I wrote.
My buffer address is 0x002427d0. But the REG_DMA27_ADDRSTART is 200BE810.
However the DMA27 could get DMA interrupt and receive data correctly when I watch the data start on 200BE810.
A new discovery， when I click the button "Restart" on CCES, the pREG_DMA27_ADDRSTART register got 0x002427d0.
But DMA27 not working or only recive one byte, and got error stat.
Thanks everyone who helps me !
