I set an EEPROM section at 0x4E00 in Bootloader.And I want to read and write EEPROM at same address(0x4E00)in bootloaderable.The start address of bootloaderable is 0x6000.If I define the same address ,it shows that wrong image overlaps section .
Please note that the Emulated EEPROM will take double the size of what you set because it will use the extra space to keep the copy of data. Once you use Emulated EEPROM you do not have to use the flash write APIs. You can use the Emulated EEPROM APIs only. Please note that you have to uncheck the "Verify Application Checksum column" in the Bootloader component as mentioned in the following link.
Another method is you can use checksum exclude region as shown in the below link. In this method you do not have to use the Emulated EEPROM component. You have to use Flash write APIs directly.
Please note that the flashwrite API will write complete row only. You have to read the flash row first, modify the bytes and then write the complete row. This is the hardware limitation.
The size of EEPROM is 256.The flash write APIs CySysFlashwrite api changes 128 byte.sometime I only want to change four bytes and other bytes reserved.
