Please note that flash parts used on ON-board flash and on the internal-sip have minor difference. so it is expected to have difference in cfg file. 2. So it depends on both controller and Flash, for OSPI COntroller you can use 133Mhz max clock frequency, please check if flash supports the same. 3. It depends on the boot mode that you will select 4. It depends on the boot mode that you will use and also you need to select corresponding clock setting, please refer to SBL examples in SDK for better reference 5. For faster configuration/clk is recommended to enabled phy.
