Hi,

I need to apply the virtual EEPROM on a RA2E1. In principle, this mechanism works, and I can write and read the record IDs. During the production of the board, I need to program the original content of this rec id. Is there any documentation or example on how to make the memory address’s binary file starting from 0x40100000?

Thanks, Nidhi

    Hi Nidhi,

    Thanks for reaching out to Volt.Tech Engineering Community.

    If I understand right you need to program the data flash of the device just right?
    The data flash can be written in both ways, by Renesas Flash Programmer, or by self-programming (by the software running on the device).

    To program only the data flash with Renesas Flash Programmer, the file used to program the device would require to hold only data for the data flash address range. A. srec,. hex, or. bin file can be used with RFP to give the data to be programmed into the flash.

    Regards

Hello, Dear Volt Tech support team, I’m using the TLE987X chip. I already read the Application note” Infineon-TLE987x_Data_Flash_Handling- AN-v01_01- EN” I want a C programming samples code for 1. Pushing data to EEPROM 2. Fetching data from EEPROM 3. Clearing the EEPROM Thank You

    Hi @nidhi, As the sample code is for TLE9879QXA40 and you're applying TLE9872QTW40 so please make the following changes- Please go to Options for Target in Keil also- 1) Go to the Device menu and add your device TLE9872QTW40 also uncheck the BF stepping to make the code compatible with your device.Read more

    Hi nidhi singh,

    As the sample code is for TLE9879QXA40 and you’re applying TLE9872QTW40 so please make the following changes-

    Please go to Options for Target in Keil also-

    1) Go to the Device menu and add your device TLE9872QTW40 also uncheck the BF stepping to make the code compatible with your device.

    Go to Debug menu-> Settings-> Flash Download and confirm if TLE9872QTW40 with 252k size is selected.

    2) Now open the config wizard, go to PMU-> Power Saving Modes, select Sleep mode, and save it.

    3) Rebuild your project and check page 0 with address 0x1103F000.

    Best Regards
    Alex Thomas

In one of our product, I want to write a bit/byte in EEPROM and after reset I will going to read & write a flag. Can you suggest how I can do this?

    Yes you can use WDT in this case. When power failure detected, WDT will trigger interrupt, in interrupt routine store required bit/byte in EEPROM. Once power retains read EEPROM and based on retrieved bit/byte update flag. Hope this will answer your question.
