TMS570LS1224: FEE addressable driver

Hello,

The data in bank 7 written using FEE driver can not be read using the address directly. It has to be read by block number using the FEE driver.

How often do you update your calibration data? If the calibration data is constant, you can program the data to a dedicated address using F021 API.

If you keep changing the calibration data during your application, you need to use the FEE driver to write the data to bank 7.

Hi QJ Wang,

Many thanks for your reply. I don't need to update it regularly, only when XCP requested to change the data.

Do you have an example using F021 API for bank 7? I was trying to use F021 API, but I found an issue that I don't know how to do it properly.

For example I wanna change a calibration data type uint32 at 0xF0200008, how can I do that? Do I have to delete the whole sector first? If so, it will affect the other calibration data. What is the correct way to use it?

Many thanks

Phil

Hi Phil,

Please use the attached files example of using F021 flash API library:
