Hi ,
I am working over IMX solo and need to decide the boot option. Here , I am considering the case of sdcard as boot option. As reading from SDcard is slow , so the booting time will increase certainly. Also , as the secondary storage which is SDcard in our case would be mapped as Virtual memory in the operating system. So during execution ,when page faults occurs ( when page entry is not available in the page table) , operating system will swap-in the page from the secondary storage (Sdcard) to the main memory i.e. DRAM. So , As per my understanding , this Swap-in and Swap out time will be greater in the case of SDCard and it will impact the performance of the system. If we use NAND Flash , probably we can minimize the Swap-in and Swap out time . Please confirm.
