Linux: AM335X :Does the EDMA can transfer data from SDRAM to internal SRAM(0x402F0400)

Tool/software: Linux

Hi All,

   I find the EDMA can not transfer SDRAM to internal SRAM.The data in the  internal SRAM can't be updated after the EDMA transfer complete.

  However,the EDMA can update the data in the L3 OCMC0 SRAM successfully.
