What is the flash erase and write operation time of mpc5744p? I can't find the parameters in the user manual.

In addition, when I do a project of Program bootloader , the upper computer can send 1.5MB files within 80s, but it takes more than 3 minutes to complete the whole Program / download process. What is the reason?

Hello,

What is the flash erase and write operation time of mpc5744p?

Please have a look at datasheet for it: 3.16.1.1 Flash memory program and erase specifications

This depends on how do you program the device. For some serial communication it depends on settings and HW limits or for JTAG / NEXUS it depends on programmer spec, etc... there can be lot of delays.

Best regards,

Peter

Programming is an extremely exciting world of creativity and logic, but it can be challenging at times. It's cool that there are services like https://programmingdoer.com/do-my-python-homework that can help you out by walking you through the tasks you may encounter. This can be a real support when you need help with programming assignments, allowing you to better understand the material and go through the difficult parts with more confidence.

I can't find the programming characteristics in Document Number: MPC5744PRM  Rev. 6.1, 10/2017.

Hello,

It is because you are referring to reference manual.

the device characteristics are described in data sheet:

https://www.nxp.com/docs/en/data-sheet/MPC5744P.pdf

Peter
