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

    Hi Nidhi,

    Thanks for posting your question online.

    In setup to perform floating point operations with library calls, you should add-mfloat-abi = soft. Please refer to-mfloat-abi = name on https//gcc.gnu.org/onlinedocs/gcc-4.4.7/gcc/ARM-Options.html

    In setup to apply functions printf and scanf functions, you should add these 2 linker options

    Hope it helps

    Regards

    The RA2E1 - 32 pin part support total 11 cap touch pin  , if used then one for shiled & other 10 can be used as CAP touch buttons
