CCS/TMS570LS3137: TMS570LS3137 - can not read value of EEPROM

Hello Krunal,

Many applications require storing small quantities of system related data (e.g., calibration values, device configuration) in a non-volatile memory, so that it can be used, modified or reused even after power cycling the system. EEPROMs are primarily used for this purpose. EEPROMs have the ability to erase and write individual bytes of memory many times over and the programmed locations retain the data over a long period even when the system is powered down.

We provide the FEE (EEPROM) driver in HALCoGen. The FEE driver provides the following functions (API) services:

Initialization:

• TI_Fee_Init  

Operations:

• TI_Fee_WriteAsync
• TI_Fee_WriteSync
• TI_Fee_Read
• TI_Fee_EraseImmediateBlock
• TI_Fee_InvalidateBlock
• TI_Fee_Shutdown  
• TI_Fee_Cancel
• TI_Fee_Format

etc

The address in flash API is 32-word aligned (0x00, 0x04, 0x08, ...), otherwise you will get an error.

 

I have enable FEE driver in CCS In Reference to the above code shared in link, Which address location has been erased. Which API is used for writing data into particular location?

7331.example_TI_Fee_Write_Read.c

I have question regarding example code you have given in Halcogen. In TI_Fee_WriteAsync() API, There is no writing Adrress location specified. Than How can we read from address location. So can you just Help me out from problem? or If you have any code snippet, than Share with us.

Thank you and Regards

Dear sir,
you are right. but in previous link code I can read and write at particular address. But in example code from block number wise we have to check read and writing process. for my application , I want Write data at EEPROM location and than Read that from the location. which is working in previous code. I am asking you that Previous document code is not for EEPRPOM? Thank you
