Hello, we have designed a board with 32 MB (32x)of SDRAM (2 IC of 16x in parallel) and MCF5272. We have problem when VxWorks is booting and shows an access error or freezes. We have this problem in almost 50 % of the boards.The SDRAM IC's are Micron and we use recommended configuration in MCF5272 datasheet. We have designed another board with the same micro and operating system but SDRAM in x16 configuration without problems.
Anybody has the same problem ?
Thanks in advance.
