DO any one faced some problem in updating the
SDRAM interfaced to your target, In the CCS whenever
it comes up. The SDRAM memory area is shown as oxffff.

Or a larger SDRAM? The largest one readily available that fits standard JEDEC site
is 8M x 32, or 256 Mbit.

TI documentation for the 5501/5502 EMIF (SPRU621D) suggests that it is
compatable with 64Mbit SDRAM. That would be 2Mx32-bit or 8MB of data.
The maximum CE spa...
