Hi,
I am using MPC5777C with system clock 192MHz and platform clock for flash is 96MHz. I want to configure the flash optimization to make MPC5777C run faster. Can you suggest me in details how to do it?
thanks and Regards,
Sourabh
Hi, pay attention to chapter 4.1 in AN5191 describing process of flash optimization. RWSC and APC value for flatp=96MHz you may find in device's datasheet, section 3.12.6.

Can you please tell me what is Flash memory read latency on mini-cache hit or miss value signify?
i am using MPC5777C with platform clock 96MHz so for this Flash memory read latency on mini-cache hit or miss value is 5 and 1. so does this meaning and how to calculate read latency in terms of time?
Flash controller on this device contain mini-cache memory (instead of simple preftech buffer) where every cache line (i.e. set) consists of 32 bytes.
If read data are already pre-fetched (for instance they are accessed second time) then access time is 1 platform clock, it is cache hit.
If read data are not pre-fetched (for instance accessed first time) then access time 5 platfrom clocks, it is cache miss.
Hi,
Do you have any flash optimization code?
Hi David,
How to measure the performance after doing flash optimization? Is there any particular code for this where i can check the performance of code?
