AM335x GPMC to DSP interface

Other Parts Discussed in Thread: AM3352

Hi all,

- I need to Configure the interface GPMC to DSP is possible in AM3352 or not.

- If possible, Please specify the steps, how to configure, i read the document of all configuration GPMC and  external memory peripherals present in the AM3352 datasheet.

- in the CS configuration time must mentioned the CS size and Base address, i give the Base address 0x2F and how to give CS size of external device ,i interfacing the GPMC to DSP processor (this is a processor not a NAND and NOR flash), How to give the size of CS to connected on external peripheral for DSP.


IN Code,

GPMC_CS_SIZE_256MB -- For Chip-select size of 256 MB.\n
* GPMC_CS_SIZE_128MB -- For Chip-select size of 128 MB.\n
* GPMC_CS_SIZE_64MB -- For Chip-select size of 64 MB.\n
* GPMC_CS_SIZE_32MB -- For Chip-select size of 32 MB.\n

* GPMC_CS_SIZE_16MB -- For Chip-select size of 16 MB.\n

- The GPMC  support up to 256MB size of external peripheral, i read from AM3352 datasheet, here, my interface DSP how to mentioned the size of DSP, Please specify the how to configure the CS.

 

Thanks in advance,

Vamsi.
