[Anonymous]

Hi,I have added two emulated eeprom component fixed at address 0xF000 and 0xF800. In map file assigned addresses are showing correctly.

Read and write operation executing perfectly. But when i reprogram device eeprom data gets erased.

Please help me resolve this issue.

I am using cy8c4246axi controller.

Emulated eeprom is not eeprom but FLASH, it will be erased when silicon re-program.

!

CY8C4246 seems a PSoC4200M device, this family part have "4 row* 128 bytes "  user sflash space can be used to store user data. This 4 rows SFLASH won't be erased when silicon re-program. You can refer cyboot-->CyFlash.c/CyFlash.h to know how to program these rows.

I  successfully stored data in sflash and its working fine.
