Look at the bus width, number of banks, rows and columns the SDRAMC is programmed to access to determine the RAM size for the board, rather than hard-wiring it to be 32MB. My company's board with 64MB now probes correctly, as does the KB9202 with only 32MB. This means that to detect the right memory size, our boot loader must correctly initialize these values. This is a fairly safe assumption because the boot loader has to initialize SDRAM already, and it isn't really possible to change this register after we've accessed SDRAM. |
