- Subject: [ECOS] External SRAM on EB40a
I have an AT91EB40A evaluation board equipped with external SRAM (SAMSUNG
k6r4008v1c, (512Kx8bits)x2).
Redboot is loaded to upper half of flash at address 0x01100000. (Redboot can
also run from on-chip SRAM.)
Can anybody tell me what kind of modification that are required to access
the external RAM? When I try to load the hello-world application to external
RAM, Redboot keeeps telling me that there is no RAM at address 0x2000000 and
refuses to load.
I have used "configtool" to generate the ecos application.
