How to reduce init time for EEPROM Emulation Software of MPC5744

[liujinhang]

Hello all，

  I found that the initialization time was very unstable of  EEPROM Emulation Software Driver。Sometimes the 25ms are sometimes 38ms。Even when the power supply is fast up and down, it can reach more than 400 ms。

In fact, we just read the eeprom in power up。We hope that the shorter the initialization  time, the better

So，I have two questions。

1、I want to shorten the initialization time to ensure that our product is stable。How to do it？

2、If just readding EEPROM in power up，can be simply initialized EEPROM？And it is time can be very brief？How to do simply initialized？

Hello,

About which EEPROM driver are you talking?

One from NXP web site?

https://www.nxp.com/downloads/en/device-drivers/MPC5xxx_EEE_DRIVER.exe 

or AUTOSAR one?

or Third party driver?

I can address your question to expert if this is related to NXP product, but you must be more specific.

That should be the driver from the NXP. I also have discovered this problem when using the driver. Can you help me to address this problem?
