I designed a custom board based on i.MX25 PDK, which is working fine. The silicon version of this processor is 1.1. For my new design (similar to the previous), I am going to use a i.MX253 processor with silicon version 1.2. I have found no information on what this could mean for my new design. Is there any hardware or software issue I should consider over the previous silicon version?
Otherwise, the last version of ATK tool has only two options for i.MX25 processors: i.MX25_TO1.0 or i.MX25_TO1.1. Can I still use ATK for flashing Nand Flash with the silicon version 1.2?
