Other Parts Discussed in Thread: OMAP-L137

Hi,

I know that OMAP-L137 supports SDRAM and NAND flash.

There are 512Mbit SDRAM data space and 128Mbit async data sapce in memory map of OMAP-L137.

Does OMAP-L137 support 64Mbytes SDRAM and 16Mbytes NAND flash?

64Mbytes and 16Mbytes is max capacity?

    Actually it is 512M bytes and 128Mbytes of memory mapped space, not bits. But the addressable space for SDRAM is 128Mbytes for EMIFA and 256Mbytes for EMIFB . You can see that on page 1 of the datasheet.

    Yes and Yes. For the NAND memories supported by the bootloader, please see page 24 of the document:

    No. Again, the addressable space for SDRAM is 128Mbytes for EMIFA and 256Mbytes for EMIFB. For NAND, the bootloader supports up to 2GB.
